All FAQs
Ask directly, and ask what would cause it to. Our quoted figure is what you pay unless you request a change, which is why we spend longer at the first visit reading the ground, tracing drains and checking access than a quick measure up would take.
Modest in a well-insulated, airtight building, because a small heater warms it quickly and it holds temperature. An uninsulated garden building with a fan heater running all day is the version that shows on a bill.
It can, though anyone quoting a percentage is guessing. What is reliable is that a properly built, insulated room reads as usable space to a buyer. If it contains sleeping accommodation, the completion certificate is what a buyer’s solicitor will ask to see.
Glazing proportion, internal finishes and sometimes the footprint, though going too small is the change people most often regret. Avoid economising on the base, insulation, roof detailing or ventilation, since all four are buried and none can be improved later without taking something apart.
If the contract was signed in your home rather than at a trader’s premises, you generally have fourteen days to cancel under consumer contract rules. If you asked for work to start inside that period, you may owe for what has already been done.
A reasonable deposit before work begins is normal practice. A large sum handed over before you have a detailed written specification is not. Ask for the payment schedule in writing before agreeing to anything.
Materials come through the house or over a boundary, which takes longer and adds labour. It rarely rules a project out and should be reflected in the quote rather than raised as a variation later.
Generally yes, because the base has to be stepped or built up on one side. It is worth having measured properly at the quote stage rather than discovered when work starts, since it is a groundworks cost rather than a building one.
They add design work, an application fee and inspection stages. Whether you need approval depends on floor area, boundary distance and whether anyone will sleep in the room, so a small change in position can move you either side of the threshold.
Where it is needed, yes, through the application fee and any drawings required. Most garden rooms fall under permitted development and avoid this. Where a Lawful Development Certificate is worth having for certainty, that carries a lower fee than a full application.
Almost always scope rather than margin. Compare what each includes for the base, groundworks, spoil removal, the electrical supply, certification and internal finishes. A shell delivered to a prepared base and a finished room are two different products.
Yes, at the standard rate, because construction of an outbuilding for an existing home is standard rated. If a quote looks unusually low, check whether the company is VAT registered, since businesses below the £90,000 threshold do not charge it and the comparison is therefore not like for like.
Usually, on a cost per square metre basis, and it avoids the disruption of building work inside the house. An extension makes more sense where the space has to connect directly to the rest of the home, such as a kitchen. A garden room suits anything better for being separate.
Less than you would think. Doubling the floor area does not double the price, because the base preparation, the services run and the setup costs are largely fixed. Going slightly larger is often better value per square metre than trimming down.
Groundworks and the base surprise most people, particularly on shrinkable clay or a sloping plot. After that it tends to be glazing and, where relevant, drainage. The building itself is rarely the line people expect it to be.
Because the base is often the largest single variable and it cannot be assessed remotely. A figure given blind would either be padded to cover the worst case or too low and revised later, and neither helps you compare quotes properly.
No. They are entirely separate systems, and one says nothing about the other. Planning governs whether the building may exist there. Building regulations govern how it is constructed and whether it is safe to use.
Not where the building is permitted development, since no application is being made. Where planning permission is required, neighbours are consulted as part of the process. A conversation beforehand is still sensible if the building will sit near a shared boundary.
Ten years in England for work substantially completed on or after 25 April 2024. The previous four-year period for building work was abolished by the Levelling-up and Regeneration Act 2023. Work finished before that date keeps the old four-year limit under transitional provisions.
A formal ruling from your council that what you propose does not require planning permission. It is not permission itself but a legal confirmation you did not need it, and it is the only way to get certainty in writing before building.
Often, depending on scale. A single person working quietly is usually fine. Clients arriving throughout the day, staff, deliveries or signage can amount to a material change of use requiring permission, and may attract business rates on the part of the property used exclusively for work.
Not under permitted development, because sleeping accommodation is not treated as incidental to the house. It also removes the building regulations exemption entirely, whatever the size. Both positions have to be dealt with properly if overnight use is the intention.
Any outbuilding within the curtilage of a listed building needs planning permission. There is no exemption. Depending on what is proposed, listed building consent may be needed too, and the effect on the setting will be considered.
Not for a typical garden room. Green Belt is not classed as designated land for the outbuilding rules, so the extra restrictions that apply in conservation areas and AONBs do not apply to it. Normal permitted development rights remain available.
Generally yes, though additional restrictions apply and some councils have removed rights further through Article 4 directions. Outbuildings to the side of the house need permission on designated land. It is worth confirming your position with your council before designing anything.
Only up to a point. Verandas, balconies and raised platforms are excluded from permitted development, and a platform means anything more than 0.3m above ground level. Low level decking is usually fine, but a raised deck can take an otherwise compliant project outside the rules.
Yes. The rule limiting coverage to half the land around the original house counts all buildings and additions together, including sheds, previous extensions and any other outbuilding. On a small plot this can be the binding constraint.
No, not under permitted development. Outbuildings cannot go forward of the principal elevation of the original house, which rules out front gardens and side positions in front of the building line.
The legal boundary of your property, which is not always where the fence sits. If there is any doubt, your title plan is the place to check rather than assuming the fence is in the right position.
Because it reduces your maximum height by a third and takes the internal ceiling with it. Once the base, floor and roof structure are deducted from 2.5m, the room inside is noticeably lower. Moving the building beyond 2m of every boundary restores the taller limit.
Three limits apply together. Eaves must not exceed 2.5m, overall height must not exceed 4m for a dual pitched roof or 3m for any other roof, and if any part of the building is within 2m of a boundary the whole thing is capped at 2.5m.
Usually not. Most garden rooms qualify as permitted development, provided they are single-storey, sit behind the front wall of the original house, stay within the height limits, and do not cover more than half the land around the original house. Conservation areas, listed buildings, flats and Article 4 directions are the main exceptions.
Ask what the core is and how thick, what the facings are, whether the base and groundworks are included, who runs and certifies the electrics, and what happens about ventilation. If your room falls between 15 and 30 square metres, ask specifically how far from the boundary it will be located and whether building regulations approval is required.
Usually yes, and it is one of the situations where SIPs are helpful. Panels are made to size and can be carried through a house or lifted over a boundary, which is far less disruptive than running a masonry build through a hallway. Access is something we assess at the first visit.
The panels themselves cost more than an equivalent area of studwork and insulation, but that is only one line in a quote. Groundworks, glazing, services and finishes usually account for far more of the total. Comparing quotes on what is included is more informative than comparing them on construction method.
Only within limits, and it is the main practical drawback of the system. Panels are manufactured with openings pre-cut, so window and door positions are effectively fixed once the drawings go to manufacture. Small internal changes are usually possible. Moving a window is not.
A weathertight SIP structure has a long service life, with 60 years commonly considered a reasonable expectation. Durability depends almost entirely on keeping water away from the panels, which comes down to roof detailing, flashings, drainage and the base.
They are wood and plastic based, so like most timber construction they will burn if a fire takes hold. Internal linings such as plasterboard provide fire protection, and the regulations handle proximity to boundaries through the exemption rules described above. The relevant question is not whether the material is combustible but whether the building is specified and sited correctly.
Yes, and more freely than in a timber frame room, because the panel faces are structural boards across their whole area rather than studs at intervals. Very heavy items such as gym racks or large wall-mounted equipment still benefit from backing planned in at design stage.
Not when they are built and ventilated correctly. The risk comes from airtightness without designed ventilation, which allows moisture to condense on cold surfaces. Approved Document F sets out the ventilation requirements, and a decent specification will include background ventilation and extraction where needed.
The shell goes up quickly, often within days once the base is ready, because the panels arrive cut to size. The overall programme is set by groundworks, glazing lead times, the electrical run from the house and the internal finish. Design and manufacture also take time before anything appears on site.
Only if it has been designed and approved for that. Any building containing sleeping accommodation needs full building regulations approval whatever its size, and the planning position has to be established separately. This is a construction project with paperwork rather than something you achieve by putting a bed in an existing room.
Not typically below 15 square metres with no sleeping accommodation. Between 15 and 30 square metres it depends on the boundary distance, and because SIPs are combustible the building needs to sit at least a metre from any boundary to stay exempt. Above 30 square metres, approval is required regardless. Electrical work is certified under Part P at any size.
Usually not, because most fall under permitted development as outbuildings. The construction method makes no difference to that. What matters is size, position, roof profile and height, plus whether your property is in a conservation area or is listed.
Polyurethane generally has a lower thermal conductivity, so it achieves a given performance in less thickness. EPS is usually less expensive. Both are used widely and both work. What matters more in practice is the total thickness specified and how well the panel joints are sealed on site.
Two structural boards, usually OSB grade 3 to BS EN 300, bonded to a rigid insulation core of either expanded polystyrene or closed-cell polyurethane. Facings are commonly 11mm to 15mm thick, and core thickness varies depending on the thermal performance required.
For the same wall thickness, generally yes. The reason is that a timber frame wall is punctuated by studs that conduct heat, while a SIP wall has continuous insulation across nearly its whole area. That said, a well-built timber frame room with a thicker wall can perform comparably. Construction quality and how well the junctions are sealed matter as much as the system itself.
Structural insulated panel. The name describes the function: a panel that provides structure and insulation as a single component rather than as two separate layers.
A garden room used as part of everyday domestic life will not normally affect your council tax. However, if you are running a business from home, using the building exclusively as office space or regularly welcoming customers, business rates may apply. If you’re using a garden office room for remote working or occasional work from home days, this is unlikely to change your council tax position, but the Valuation Office Agency can advise where circumstances are less straightforward.
Under permitted development, a dual pitched roof can reach 4m overall, while flat roofs and other roof styles are limited to 3m. Neither may exceed 2.5m within 2m of a boundary. Your choice depends on your garden room design, desired appearance and intended use. A flat roof suits a modern garden room or contemporary garden room, while a pitched roof creates a greater feeling of open space and allows more natural light.
Not under permitted development. A garden room cannot normally be built on land forward of the principal elevation of the main house without planning permission. If you want to build a garden room in your front garden, you’ll need to submit a planning application to your local authority.
It depends where you live. Bedford Borough Council covers Bedford, Central Bedfordshire Council covers Marston Moretaine and many surrounding areas, while Luton, Milton Keynes and West Northamptonshire each have their own planning authority. If you need planning permission for your garden room, contact the relevant local authority before work begins.
The build time depends on the garden room design, foundation type, site access and weather conditions. A DIY garden room may take considerably longer than a professionally installed one. Whether you’re adding a modern garden room, garden office or garden hobby room, a realistic programme can only be provided after a site visit.
Not if it is properly built and documented. A well-designed bespoke garden room can create extra space and make your property more attractive. Problems usually arise where there is no evidence of permitted development, no electrical certification or no clear documentation. Keeping the correct paperwork helps reassure buyers.
Legally, no, if the building is exempt. In practice, good insulation is highly recommended if you want to use your insulated garden room throughout the year round. Properly insulate the walls, roof and floor to reduce heating costs, improve comfort and prevent condensation. Whether it’s a garden office, garden gym, workspace or hobby room, insulation makes a significant difference.
Yes. A garden room can include a toilet or sink, but drainage and water supply need careful planning. Waste must connect properly to the existing foul drainage system, while water pipes should be installed below frost depth. This is common in garden offices, garden studios, garden bars and other buildings intended for year round use.
It can. Mature trees remove large amounts of water from clay soils during the summer, increasing seasonal movement beneath a garden room or garden building. Removing a tree can also cause the ground to swell as moisture returns. If you’re creating a new garden layout or adding a bespoke garden room, tell your builder about any nearby trees before the design is finalised.
The right foundation depends on the ground beneath your garden room. Across the Marston Vale, shrinkable Oxford Clay often requires deeper foundations or systems such as screw piles to reduce movement. Whether you’re planning a modern garden room, wooden garden room or garden studio, the foundation should always suit the site rather than follow a standard specification.
You can usually build a garden room right up to the boundary under permitted development, but anything within 2m of the fence cannot exceed 2.5m in overall height. If your garden room falls between 15 and 30 square metres, remaining at least one metre from every boundary is one way to retain the building regulations exemption. Measurements include roof overhangs, not just the walls.
Yes. Installing a new circuit to supply a garden office, garden gym, garden bar or other garden room is notifiable work under Part P in England. It must either be carried out by a registered electrician or notified to building control beforehand. This applies even where the garden building itself is exempt from building regulations, and you should always receive an Electrical Installation Certificate.
Occasional overnight use is different from creating a separate dwelling, but any sleeping accommodation removes the building regulations exemption regardless of size. Permitted development for a garden room or garden cabin does not extend to self-contained living accommodation. If you want a building that functions as more than extra space away from the house, you should involve building control from the start.
Not normally if your garden room is under 15 square metres with no sleeping accommodation. Between 15 and 30 square metres it is also normally exempt, provided there is no sleeping accommodation, and it is either at least a metre from every boundary or built substantially of non-combustible materials. If you’re creating an insulated garden room, garden office room or another heated living space, you’ll still want good insulation and construction standards even where formal approval isn’t required.
There is no maximum floor area under permitted development, only the rule that no more than 50 per cent of the land around the original house can be covered. Height is usually the limiting factor rather than the footprint. Whether you’re planning a small garden room, garden office, garden studio or a larger garden building, the floor area mainly affects building regulations rather than planning permission.
Usually not, if your garden room is built under permitted development rights and stays within the size and height limits. The main restrictions are 2.5m maximum overall height within 2m of a boundary, 4m for a dual pitched roof or 3m for any other roof elsewhere, nothing forward of the principal elevation of the main house, and no more than half the land around the original house covered. Listed buildings always need planning permission, while flats and maisonettes do not benefit from permitted development. If you’re planning your garden room, it’s worth checking the rules before you build.
Call 01234 959502 or email info@pro-assist.co.uk. Before we visit, it helps to have a rough idea of what has to fit inside and roughly where in the garden it might go. You do not need measurements or drawings. We work the rest out on the day.
Ask when you get in touch, and have a look at our recent projects. We would far rather you spoke to someone who has lived with one of our buildings through a winter than simply took our word for it, and most of our work arrives through people willing to do exactly that.
On paper, yes. In practice you are buying a shell and taking on the groundworks, the electrics and the finishing yourself, or finding and coordinating three trades to do it. By the time all of that is priced, the gap narrows sharply, and the parts you cannot see afterwards are the ones that decide whether the building still performs in ten years.
For most home businesses this is straightforward, though it depends on scale. A one person workspace or studio is generally fine. Staff, clients arriving in numbers, deliveries or signage start to look like a change of use to a planning department, and may attract business rates on the part of the property used exclusively for work. Tell us what you have in mind and we will give you an honest view.
It can, which is why we never quote a base before seeing it. Bedfordshire’s ground varies more than most counties. The Marston Vale is heavy Oxford Clay, the same clay the Stewartby brickworks were built on, and it swells and shrinks through the year. The Greensand Ridge running through Woburn, Ampthill and Sandy gives free draining sand. Head south towards Dunstable and you are onto chalk. Three soils, three different bases.
Usually not. Most garden rooms are permitted development, provided the building is single storey, sits behind the front wall of the house, covers no more than half the land around the original house, and stays inside the height limits. Conservation areas, listed buildings and flats are treated differently. One local point worth knowing: parts of south Bedfordshire around Dunstable, Whipsnade and Totternhoe sit inside the Chilterns National Landscape, where an outbuilding more than 20 metres from the house is capped at 10 square metres before permission is needed. Twenty metres is not far down a long garden.
There is no Bedfordshire County Council anymore, which surprises a lot of people. It was abolished in 2009 and replaced by three unitary authorities. Bedford Borough covers Bedford, Kempston and the villages north and east. Central Bedfordshire covers a wide sweep including Ampthill, Flitwick, Biggleswade, Sandy, Dunstable and Leighton Buzzard. Luton Borough covers Luton. Each runs its own planning and building control.
Less than people assume when it is built properly, and considerably more when it is not. Real insulation and airtightness mean a small heater warms the room quickly and it stays there. An uninsulated garden building with a fan heater running all day is the version that shows up on a bill.
It can, though anyone quoting a percentage is guessing. What is reliable is that quality garden rooms read as genuine extra space to a buyer, while a shed with a socket does not. If yours contains sleeping accommodation, the completion certificate is what a buyer’s solicitor will ask for, which is a strong argument for doing it correctly first time.
A properly built, insulated room with a maintained roof should be a permanent building rather than a fifteen year one. What shortens that is water: a poor roof detail, a base sitting in wet ground, or timber left untreated. Every one of those is a construction decision rather than a problem that appears on its own.
We can, though it is a different type of project. Garden annexes containing a bed need full building regulations approval whatever their size, and the planning position has to be settled separately. Entirely doable, and we handle the approvals as part of the job, but tell us at the outset so we take the right route from the beginning.
A garden office is the most common by a wide margin, and a properly insulated garden room is ideal for offices in a way a converted shed never manages. Beyond that we build gyms, garden studios, an art studio here and there, hobby and leisure rooms, entertainment space with a bar, and a fair number of rooms that quietly become the best part of the house.
Too small, and consistently so. Trimming a metre saves less than homeowners expect and costs you a piece of furniture, a workable doorway, or the swing of a door for the life of the building. Work out what has to fit first, then check whether the garden allows it. Full-height glazing helps a compact room feel open and airy rather than boxed in.
Every one is bespoke. We do not sell a fixed range of garden rooms with set footprints, because a bespoke building designed around your plot will always use your outdoor space better than something chosen from a brochure. Layout, roof profile, glazing and cladding are all decided with you, so there are plenty of options available, from timber cladding that weathers naturally to a low maintenance composite finish.
Considerably. Summerhouses and most flat pack pods have thin walls and minimal insulation, which is why they are pleasant in June and unusable by November. Ours are fully insulated buildings constructed from SIP panels, so the room holds heat properly and stays comfortable year-round. A shed with a plug socket in it is a shed. This is living space.
Depends what it is for. An extension suits anything that has to connect to the rest of the house, like a kitchen or a bathroom. A garden room suits anything better for being separate: a home office, a gym, guests, noise, or clients arriving. It usually costs less per square metre, and you carry on living normally while it goes up rather than living around dust for three months.
Yes, unless you change something. That is exactly why we spend longer at the first visit than most: reading the ground, tracing drains, checking access and looking at trees is how a price stays a price. If we get something wrong, that lands on us rather than your invoice.
Nothing for the consultation or the quote. Payment for the build is staged and written into the quote so you can see the schedule before agreeing to anything. Be wary of any company asking for a large deposit before you have a full written spec in your hand.
No. Our own tradesmen carry out the build, and where a specialist qualification is needed that person still works to us rather than to you. You are never coordinating trades or waiting on somebody else’s diary. We act as your project managers as well as your builders, so there is one quote and one number to ring.
Take a sheet of paper and write five headings: base, shell, electrics, internal finish, and who certifies what. Work through each quote and mark every line as included, excluded or unclear. The unclear column is usually where the difference lives, and it is a perfectly reasonable thing to ring and ask about.
Site preparation, the base, the building, insulation, roof, windows and glazing, the electrical supply run from your house, sockets, lighting, certification, plastering, flooring, decoration and clearing up after ourselves. Plumbing too where your brief calls for it. There is no separate installation charge and no delivery fee, because we install garden rooms rather than drop them off. One team handles it start to finish.
Almost always because they cover less. The usual exclusions are the base, the groundworks, the electrical supply from the house, certification, delivery, and sometimes the internal finish. A price for a delivered shell and a price for a finished room are two very different things. When you compare, line the quotes up on what is included rather than what is printed on the front page.
Call 01234 959502 or email info@pro-assist.co.uk. Include your postcode when you get in touch, because that lets our team check the conservation area, listed building and Article 4 position before we arrive. You will deal with the same professional and friendly people from the first visit through to handover, which is the level of service most of our work comes back to us on.
Size, foundation design, glazing, services and finish all move the figure, and an address requiring planning permission carries costs that one under permitted development does not. After a visit, you get an itemised written quote with nothing buried in it.
The shell goes up quickly. What sets the real timescale is the approvals route where one is needed, then groundworks, glazing lead times and the internal finish. We give you an honest view of both halves at quote stage rather than a build time that quietly ignores the paperwork.
A DIY pod or self-build kit gives you a shell and leaves the difficult parts to you, which usually means finding a groundworker, an electrician and a plasterer yourself and coordinating all three. We handle designing and building the room from start to finish, including the foundation, services and finishes. The craftsmanship and attention to detail on the parts you cannot see afterwards is what determines whether the room still performs in ten years.
In Cambridge, usually by a wide margin. Once you have added stamp duty, agent fees, legal costs and the price difference on a larger house, moving for one extra room rarely stacks up. An extension means months of upheaval inside the house and often costs more per square metre than a garden building. This route gets you extra space without either.
It should be, and that is what separates a properly built room from a summerhouse. A fully insulated, high performance build keeps heat where you want it, so a modest heater handles a cold morning. Ventilation is designed in at the same time, because an airtight room without it will end up damp. A 3m by 4m room built this way is comfortable in February and cool enough in July.
Yes. A certified electrician takes the supply from your consumer unit and signs it off under Part P. We plan every socket, light and data point around how the room will actually be used. For an office, running wired data while the walls are open is worth doing and costs very little at that stage.
Yes. It needs a water supply, hot water and a proper connection to your foul drainage, which is construction work rather than an accessory. The distance from the building to your existing drain usually drives the cost, so we trace it during the site visit rather than estimating it from a plan.
Only where it has been designed and approved for it. Any building containing sleeping accommodation needs full building regulations approval regardless of size, and the planning position has to be settled separately. Garden annexes with a bedroom, toilet and shower are entirely buildable, and are often what people mean when they talk about a granny annexe, but they are a construction project rather than a purchase. Say so at the start and we will take you down the correct route.
Not normally below 15 square metres with no sleeping accommodation. Between 15 and 30 square metres it stays exempt provided there is no sleeping accommodation and the building sits at least a metre from a boundary or uses substantially non combustible materials. Over 30 square metres, approval is required. Electrical work is certified whatever the floor area.
Yes. Eddington, Northstowe, Cambourne and the newer village extensions often operate design codes or an estate management company with its own approval process, running entirely separately from planning. It is easy to overlook, so check your deeds and any estate documentation early.
All sorts. The most common by a distance is a workspace, since a garden studio is ideal for offices and gives you a genuine work-life separation that a spare bedroom never quite manages. Beyond that we build gyms, hobby rooms, an art studio here and there, workshops, music rooms and quiet hideaways for reading. Because the room is fully insulated, it works year round rather than emptying out every October.
Yes. Every building we do is bespoke rather than chosen from a catalogue, so cladding, roof profile, colour and glazing are all decided with you. Some people want a stylish contemporary studio with sliding doors onto a deck. Others want something quieter in timber that sits softly at the end of the garden. There is a wide range of options available, and we tailor the design to the house rather than the other way round.
Frequently, yes. The real constraint is the rule limiting buildings to half the land around the original house, which bites much sooner on a compact plot, particularly if a shed or an existing extension already counts towards it. We measure what is genuinely available and size the room from that, then use full-height glazing and a light interior to keep even a modest footprint feeling open and airy.
Yes, and that describes a great many Cambridge properties. The Victorian terraces around Mill Road, Romsey, Petersfield and Newnham rarely have side access, so materials come through the house or over the boundary. It calls for planning and care with your floors and doorways, but our team does it regularly and it seldom rules a project out.
Gault Clay is highly plastic, which is the technical way of saying it swells and shrinks more than most soils as moisture levels change through the year. The foundation has to be designed around that rather than dug to a default depth. Because our garden buildings are relatively light, ground screws or a piled base frequently outperform a concrete slab and take far less out of your outdoor space. We specify after a site visit, never before.
Two separate things. If the tree carries a preservation order, or simply stands within a conservation area, you must give the council written notice before doing any work on it, and in a conservation area that means six weeks. Separately, tree roots and shrinkable clay interact in ways that affect the foundation design. We look at both before committing to a position in the garden.
It is a direction removing specific permitted development rights across a defined area, and Cambridge has several. If one applies to your street, work that would ordinarily proceed without an application may need permission. It is not something most homeowners would know about, so we check it against your address at the outset.
Usually yes, though it needs handling carefully. A new building in the garden of a listed property will almost always require planning permission, and the effect on the setting becomes a material consideration. That influences where the room sits, how tall it is and what it is clad in. We design around those constraints rather than submitting a standard drawing and hoping, and it is a longer route rather than a closed one.
No, but it changes the process and sometimes the design. Permitted development rights can be reduced, so an application may be needed where a house elsewhere would not require one. Materials, roof profile and how visible the building is from the street all carry more weight, which is where a fully bespoke approach helps. Timber cladding and a lower, quieter profile will usually sit more comfortably in a sensitive setting than something aggressively modern.
Cambridge City Council for the city itself, South Cambridgeshire District Council for the surrounding villages. The two run a shared planning service, which makes things more consistent than they once were, though they remain separate authorities. Head towards Ely and you reach East Cambridgeshire, west and you are into Huntingdonshire. We install garden rooms throughout Cambridgeshire, so we are used to working with each of them, and we confirm which covers your postcode before anything else happens.
Often you will not, but Cambridge is one of the places where the exceptions bite hardest. The standard rules allow a garden building without permission provided it is single storey, sits behind the front wall of the house, covers no more than half the land around the original house, and stays within 4m overall for a dual pitched roof, 3m for anything else, or 2.5m if any part comes within 2m of a boundary. Conservation area status, listed buildings, flats and Article 4 directions all change that answer, and Cambridge has more of all four than most cities.
Call 01234 959502 or email info@pro-assist.co.uk and we will book a visit at a time that suits you. Bring a rough idea of what the room is for and roughly where it might go. Everything else we sort out on the day.
It can, though anyone quoting you a percentage is guessing. What is reliable is that a well built, insulated room reads as usable space to a buyer, while a shed with a plug socket does not. If it contains sleeping accommodation, the completion certificate is what a buyer’s solicitor will ask for, which is a strong argument for doing it properly first time.
You ring us, and we come back. We are a short run down the A428, which is the practical advantage of using a local firm rather than one operating from the far side of the country. What cover applies to your build is set out in writing before you commit, so there is nothing to argue about later.
Yes, and that is the difference between what we build and a summerhouse. Proper insulation and airtightness keep the heat inside, so a small heater deals with a cold morning rather than running flat out all day. Ventilation is designed in at the same time, because a sealed room without it goes damp within a couple of winters.
We can, though it is a different sort of project. Garden annexes with a bed in them need full building regulations approval whatever their size, and the planning position has to be settled separately. It is entirely doable and we manage the approvals as part of the job, but say so at the outset so we take the right route from the start.
Working from home is the most common by a distance, and a fully insulated studio is ideal for offices in a way a converted shed never manages. Beyond that, we build gyms, hobby rooms, an art studio here and there, a beauty room or two, and a fair number of rooms that simply become the quiet end of the house. Because the room is properly insulated, it stays usable year-round rather than emptying out every October.
Not under permitted development, though a friendly word is worth it if the building will sit near a shared boundary. Where an application is needed, neighbours are consulted as part of the process. Most objections come from noise or overlooking rather than the building itself, so we think carefully about where it sits and which way the glazing faces.
Yes, and it sits separately from planning. Newer developments around Upton, Grange Park, Wootton Fields, Collingtree and Buckton Fields commonly carry restrictive covenants or run their own approval process for anything built in a garden. Look at your deeds early. Five minutes now saves an awkward conversation later.
It happens. Northampton has a number of designated areas, including parts of the town centre, several Victorian suburbs and many of the ironstone villages around the town. Permitted development rights can be tightened inside them, so we check your address before drawing anything.
West Northamptonshire Council. It replaced Northampton Borough and the old county council in 2021, and now handles planning and building control as a single unitary authority covering Northampton, Daventry and Towcester. Cross past Wellingborough, and you are into North Northamptonshire, which is separate. We install garden rooms throughout both, so either is familiar ground.
Usually not. Most outdoor buildings of this kind are permitted development, as long as the building is single-storey, sits behind the front wall of the house, covers no more than half the land around the original house, and stays inside the height limits. Those are 4m for a dual pitched roof, 3m for anything else, and 2.5m if any part is within 2m of a boundary. Conservation areas, listed buildings and flats follow different rules.
We work through the house. It is one of the most common situations in Northampton, because the Victorian terraces went up without side gates. Floors and doorways get protected properly, components are sized to be carried by hand where the route demands it, and the whole thing is planned before day one rather than improvised on the morning.
It can. Land along the Nene through Far Cotton, Cotton End, St James and the low ground either side falls within flood zones, which changes how the base is built and where the finished floor level sits. It seldom stops a project, but it needs establishing before anything is poured.
It adds to the groundworks, so better priced properly than discovered later. Northampton sits on a hill above the Nene, and gardens around Kingsthorpe, Duston, Semilong and the streets running down towards the river often have a real fall to them. We measure it on the visit, decide whether to step the base or build one side up, and put it in the quote.
It varies more here than most places. Northamptonshire sits on a mix of ironstone, limestone and clay, and which you have can change within a few streets. Clay is the one that matters, because it swells in winter and shrinks in summer, so the base has to be designed around that movement. Our buildings are light enough that ground screws often outperform a concrete slab, cost less and leave your lawn largely intact.
Not usually. Most of our customers are out at work while we build, and a good number end up leaving us with a key. Access, working hours and where the van goes all get agreed before we start.
It moves through the year, and you will get a straight answer rather than what you want to hear. Groundworks are weather sensitive, so a winter start can slip in a way a spring one does not. We give a realistic date at quote stage and ring you if anything changes.
We build with structural insulated panels, which give you a stronger, warmer shell than a stick-built timber frame of the same thickness. Externally, you can have a wooden finish such as western red cedar, which weathers to a soft silver, or a low-maintenance composite cladding if you would rather not treat anything. Composite garden rooms cost a little more up front and give the time back in weekends you do not spend with a brush.
Every one is bespoke. We do not sell a range of garden rooms with fixed footprints, because a bespoke garden room designed around your plot will always use the garden space better than something picked from a brochure. Layout, glazing positions, roof profile and internal space are all decided with you. That is the point of a design and build service rather than a delivery and fitting one.
Small things, usually yes, and we would rather you asked than lived with something you did not want. Bigger changes cost more once materials are cut or ordered, which is why we push for detail at design stage. Deciding where the sockets go while the walls are open is free. Deciding after they are plastered is not.
No. The visit and the quote cost nothing and carry no obligation, and we do not chase you afterwards. Payment terms for the build itself are set out in writing so you can see them before committing to anything.
The figure in your written quote is what you pay, unless you ask us to change something. That is why we spend longer at the first visit than most: reading the ground, tracing drains, checking access and looking at trees is how you avoid variations later. Nobody enjoys a phone call that starts with the word unfortunately.
Our own tradesmen, and largely the same faces from start to finish. We are not a company that sells you a building then hands your address to whoever is free that week. The person who prices your job is involved while it goes up, which is the main reason things do not get lost between the quote and the build. Our design team and our fitters work for the same firm.
Possibly, but check first. Northampton has a lot of these, left over from the boot and shoe trade when outworkers made shoes in small workshops behind the terrace. Plenty survive around Far Cotton, St James, Kingsley and Semilong. Some are locally listed, some sit inside a conservation area, and a few are the reason the conservation area exists. Get the council’s view before anything comes down, because a demolished one cannot be put back. In some cases, repairing it beats replacing it, and we will say so if that is what we think.
Call 01234 959502 or email info@pro-assist.co.uk. Bring the dimensions of whatever is going in, and your height if a golf simulator is on the list. Those two things tell us far more about the building you need than the size of your lawn does.
It varies more than most types, because a room for a dartboard and a sofa is barely the same project as a simulator with a bar. After a site visit you get an itemised, no-obligation quote with no hidden fees. Our cost guide sets out what moves the figure if you want a rough sense first.
The shell goes up quickly. Acoustic layers, electrics and the internal fit out set the real programme, along with lead times on anything specialist you are having installed. We give you a realistic date range at quote stage and tell you promptly if it moves.
Yes. Every building we do is bespoke rather than picked from a range, so the cladding, roof profile, colour and glazing are all decided with you. Some people want a contemporary garden building with large sliding doors and a flat roof. Others want something softer that sits quietly against an older house. Bring your design ideas and we will work from those.
It depends what is going in. Engineered wood or good quality vinyl suits pool, darts and bar areas, because it takes knocks and mops clean. Simulators want a rigid subfloor under the hitting zone rather than anything that flexes. Carpet works in a seating corner and nowhere near a bar.
That is the honest question behind a lot of these enquiries, and it comes down to whether the room is comfortable. A cold building at the bottom of the garden gets used twice. A cosy one with proper heating, good wifi, decent seating and somewhere to put a drink becomes where everyone ends up. Designed for year-round use, it turns into the place your family and friends gravitate towards rather than a shed with a dartboard in it.
Check before you fill it. Many home policies limit cover for contents kept in outbuildings, and a table, a simulator and a screen add up quickly. Tell your insurer what is going in, and mention that the building is lockable and alarmed. We can specify locks, glazing and alarm provision accordingly.
Generally not below 15 square metres with no sleeping accommodation. Between 15 and 30 square metres it is normally still exempt if there is no sleeping accommodation and the building sits either a metre or more from a boundary or is built substantially from non combustible materials. Above 30 square metres, approval is required, and games rooms cross that line more often than other types because of the floor space the games themselves demand.
Usually not. A games room is incidental use, so most fall under permitted development as an outbuilding provided the building is single-storey, sits behind the front wall of the house, covers no more than half the surrounding land and stays inside the height limits. Conservation areas, listed buildings and flats are treated differently, so we confirm your position before designing anything.
Hotter than people expect. A projector, a gaming PC, a large screen and several people all generate heat, and a well-insulated room holds onto it. We normally specify a unit that cools as well as heats, plus ventilation sized for a full room rather than one person at a desk.
Whatever they actually use. Air hockey, darts, a table football, an arcade cabinet, a wall of board games, sim racing rigs, or simply a big screen and comfortable seating. Some rooms are a dedicated space for one thing. Most end up multifunctional, doubling as a hobby room during the week and an entertainment space at weekends. We can customise the layout around what you own now and what you are likely to add later.
Yes, and a garden pub is one of the most common briefs we get. A bar area with a sink needs water in and a foul drainage connection out, which is construction work rather than a plumbing accessory. Distance to your existing drain usually drives the cost, so we trace it on site rather than estimating. Fridges, kegerators and glass washers all need planning for at design stage.
Yes, when it is built for one. A full-size table can exceed a tonne once assembled, concentrated over a small area. The base and floor structure are designed around that weight and where it lands, so tell us which table you are buying before anything is drawn.
No, and it is worth understanding the difference before you compare quotes. A games room log cabin is built from solid timber walls, which look lovely but insulate poorly and move with the seasons, so gaps open up and heat escapes. Our buildings are properly insulated garden rooms with a sealed, framed construction, which is what makes them usable all year round rather than pleasant in June and freezing in January. A garden log cabin is generally cheaper up front. It is rarely cheaper to run.
That is what people build them for, and with the right specification it is realistic. Councils can act on noise complaints regardless of planning permission, so be straight with us about how you intend to use it. If games night regularly runs past midnight, we will tell you what your plot can support before you spend anything.
Not if the building is built to stop it, which is a design decision rather than an accessory. Sound needs mass to block it, and insulation alone will not do the job. We use a heavier wall and roof build up, isolate the floor so impact noise does not travel through the ground, seal the doors properly and specify the glazing for acoustics as well as heat. Where the building sits matters enormously and costs nothing to get right.
Yes, with a pitched roof and the right position. A dual pitched roof is allowed up to 4m overall, against 3m for a flat roof, and both drop to 2.5m if any part of the building sits within 2m of a boundary. That single rule is why simulator projects get positioned in the garden before they get designed.
About 2.7m internally at an absolute minimum, and 3m if you want to swing without thinking about it. Taller golfers need more. Because internal height is whatever is left after the floor and roof build up, it has to be designed in from the start rather than discovered on site. A 6m x 5m footprint is a comfortable starting point for a simulator with room to stand back and watch.
Only in a large one. A 12ft table wants roughly 6.7m by 5m, which uses up most of an average garden. Plenty of our customers land on a 9ft or 10ft table instead and are happier for it, because the room then works for other things too. Whether you go for snooker or pool, bring the table dimensions to the first visit and we will design around them.
For a 7ft English table played with a full-length cue, around 5m by 4m internally. The rule is the table plus a cue length plus a little clearance on every side. A 7m x 4m garden room is a popular size for exactly this reason, since it leaves plenty of space behind the table for a bar area or seating rather than filling the whole floor with the game.
Call 01234 959502 or email info@pro-assist.co.uk. The most useful thing to bring is not a measurement but an answer to two questions: who will be staying, and how often. Those shape the building more than anything else, and everything follows from there.
It depends on size, the specification of the shower room, drainage distance, finish and how far you take the design, so a single figure on a page would tell you nothing useful. After a site visit you get an itemised written quote with no hidden fees.
Longer than a standard garden office, because approvals come first and that part runs in weeks rather than days. Once on site, the build and installation move quickly. We give you a realistic view of both halves at quote stage rather than quoting a construction time that ignores the paperwork.
For a lot of people, yes. A garden room can create extra space at a fraction of the upheaval, without losing internal rooms to a corridor or living through months of work inside the house. It is a genuinely cost-effective home extension in the sense that matters, and you keep your garden usable while it happens.
Not if the roof is detailed for it, though it catches out plenty of cheaper buildings. We build in acoustic detailing so heavy rain is a background sound rather than something that wakes somebody at four in the morning.
Yes, and it is far cheaper to include now than to retrofit later. Level thresholds, wider doorways, a wet room floor instead of a shower tray and lever taps cost very little at build stage. If mobility is likely to change over the next few years, design for where things are heading.
That is one of the strongest reasons to build one. For most of the year it becomes a home office, a garden studio, a quiet place to relax, or extra living space for teenagers. Because it is already insulated and serviced to a high standard, it adapts far more easily than a standard garden room ever could.
Usually, yes. A small garden room with a well planned interior can comfortably take a double bed, a wardrobe and a shower room without dominating the outdoor space. A larger garden gives more freedom over positioning, but plenty of our work goes into modest plots, and the size is worked back from what the garden can sensibly give up.
Enough to feel like a room rather than a box, but positioned with care. Large doors and windows facing the garden give light and a view, while higher level glazing keeps things private where a neighbour’s window looks across. When we are designing your garden room we place the doors and windows around the plot rather than putting the same arrangement on every build.
Yes. Every garden room we build is bespoke rather than picked from a catalogue. Cladding can be timber for a softer, more traditional look, or a flatter, cleaner finish for a contemporary garden room. Roof profile, colour and proportions are all decided with you. The aim is a modern garden building that reads as part of the property rather than something dropped at the end of the lawn.
They generally tell us it feels more like a small hotel room than a spare bedroom. The things that make the difference are privacy, warmth, somewhere to hang clothes, room to open a suitcase, wifi that reaches, and a lit path back to the house. Get those right and a garden guest room becomes the place people ask to stay in.
This is where a fully insulated garden room earns its money. A guest lying still for eight hours feels heat loss far more than someone moving around at a desk, so the insulation standard here is higher than in a standard garden room. Built properly, the space holds warmth overnight without a heater running flat out, and stays comfortable for year-round use rather than emptying out every October.
Yes, provided it is sized correctly at the design stage. A small heater intended for hand washing will disappoint anybody standing under a shower. If more than one person might stay, we plan for two showers back to back rather than one.
Yes, and nearly all of ours do. A shower room needs water in, hot water and a proper drainage connection out. How far the building sits from your existing drain is usually what moves the cost, so we trace it on site rather than estimating from a plan.
The kitchen, more often than not. A guest bedroom with a shower room and no cooking facilities stays connected to the main house. Add a kitchen and you are into self-contained living accommodation, which is a garden annexe and a bigger application. Both are buildable, and most people who ask about an annexe actually want the first one.
Usually you will want an application or a written confirmation from your council, because guest accommodation is treated differently from a garden office or studio. For a modest garden guest room in a back garden it is rarely a difficult conversation. We will tell you where you stand at the first visit and handle the process from there.
Yes, as long as it has been built for it. Sleeping in your garden room takes it outside the usual permitted development route and means the building needs approval under building regulations, whatever its size. That is not a hurdle, just a different starting point. It sets a higher standard for insulation, ventilation and fire safety, which is exactly what you want in a room somebody spends the night in.
Call 01234 959502 or email info@pro-assist.co.uk and we will book a visit. Have your treatment list ready and a rough sense of daily client numbers, because those shape the building far more than the square metres do. Our garden rooms are designed around how hairdressers and beauty therapists actually work, and the convenience of working from home is usually what people tell us they notice first: no commute, no rent, and a clearer line between the salon and home life. Once the room is there, most people find it easier to grow their business than they expected.
It depends on size, drainage distance, hot water, electrical load, extraction and finish, so any figure printed on this page would mislead you. Every room is bespoke and tailored to the treatments you offer rather than picked from a range. After a site visit, you get an itemised written quote with no hidden fees, and against years of high street rent or chair fees most people find the sums work quickly.
The shell goes up quickly. Drainage, services and fit out set the real programme, along with lead times on any specialist equipment. High-quality work takes the time it takes, and the attention to detail on plumbing and extraction is what determines whether the room still works properly in five years. We give a realistic date range at quote stage and tell you promptly if anything moves, so you know when to start filling the diary.
You are left with a self-contained, insulated, plumbed building, which makes it the most adaptable room we build. It converts easily into a home office, a guest room, a utility space or somewhere to work from home in a completely different line of work, because the hard and expensive parts are already installed.
This is where a purpose built salon pulls away from a converted shed. A welcoming space usually comes down to a few things: a proper entrance rather than a back door, a small seating area for anyone arriving early, and enough natural light that the room feels open. Sliding doors onto a deck work well for beauty studios and treatment rooms, and give clients something to look at. It does not need to be luxurious, but it does need to feel considered, and a stylish, well finished interior in a modern garden setting is a large part of why clients rebook.
Yes, and it needs to be, because clients sitting still get cold far faster than you do while working. Good insulation holds warmth on a February morning without a heater running constantly, and climate control handles summer when a full room and a set of dryers push the temperature up. We can zone the heating so a treatment area stays warmer than a reception corner, which matters if you offer massage and wellness treatments where the client is undressed and still.
Usually not below 15 square metres with no sleeping accommodation. Between 15 and 30 square metres it is generally still exempt provided there is no sleeping accommodation and the building sits either a metre or more from any boundary or is built substantially from non combustible materials. Above 30 square metres, approval is required. That said, we insulate and glaze every room to a proper standard whatever the floor area, because insulation is what makes the difference between a room you can trade from all year and one that empties out in January. Drainage and electrical work must meet standards regardless of size.
The usual source of neighbour friction, and much easier to solve before you open than after a complaint. Spacing appointments so arrivals do not overlap, and confirming where to park when you confirm the booking, handles most of it. Late evening appointments are worth thinking about too, since car doors carry further after dark. Parking pressure also influences how a planning department views the use, so raise it early rather than late.
Yes, on two fronts. Your home policy needs to know a business operates from the property, because an undeclared one can affect the whole policy. Separately you will need public liability, treatment specific cover for the services you offer, and cover for stock and equipment kept in an outbuilding.
Something waterproof, chemically resistant and quick to clean. Cut hair, spilt product, acetone and standing water all end up on the floor, and a domestic finish will not last a year. Safety vinyl coved up the wall is the usual specification, because it mops clean and leaves no seams for hair to work into. Choosing quality materials at this stage is one of those decisions where functionality quietly matters more than how the interior photographs.
A significant one. Poor colour rendering makes hair, nails and makeup look one shade in the chair and another in the car park, which is how remakes and awkward conversations start. Colour work needs precision, so we use high colour rendering, daylight balanced lighting at each station, positioned so you are not casting a shadow over what you are doing. Large windows bring in natural light alongside it, which most clients notice before anything else in the room.
Each needs a different answer. Acrylic nail dust wants extraction at the desk where it is created. Wax, acetone and product need enough air changes to clear the room between clients. Steamers and backwashing add humidity that has to leave the building or it settles on the glazing. A therapist working with heat or oils has different requirements again, so we specify them separately rather than fitting one vent and hoping it covers everything year-round.
They will if the supply is calculated properly rather than assumed. Two dryers, straighteners, climate control and lighting running together will defeat an undersized circuit. We work out the total load, run a suitably rated cable from the main house, and place a socket at each of your styling stations at working height rather than at skirting level, so nothing trails across the floor. Every workstation gets what it needs, and the whole installation is certified under Part P.
More than most people expect. An instant heater copes with hand washing but not with back to back shampooing, and a client sitting at the basin under lukewarm water will notice immediately. If washing is a regular part of your day, stored hot water is usually the right answer, and it changes the electrical design. Tell us what a busy morning looks like, and we size it for that rather than an average.
Because of what is in it. Colour, shampoo, product and cleaning chemicals cannot be discharged to a soakaway or a surface water drain, since those run to watercourses. It has to reach foul drainage. Getting this wrong risks enforcement action, and it is one of the corners cheaper installations quietly cut.
Yes, and it is the single question worth putting to every company you get a quote from. A backwash needs a water supply, a hot water source sized for repeated hair washing, and a waste run reaching your foul drainage at the correct falls. Where ground levels rule out gravity drainage, a pumped system solves it. An experienced garden room builder will tell you which applies at quote stage rather than discovering it once the base is down, and the room has to be properly plumbed rather than fitted with a basin and hoped for.
Possibly, on the part of the property used exclusively for the business, and a purpose built room is more likely to be assessed than a spare bedroom with a couch in it. The Valuation Office Agency decides. It is often less alarming than it sounds, because small business rate relief means many a self-employed hairdresser or single therapist pays nothing once assessed. Even where rates do apply, the arrangement usually remains far more cost-effective than renting premises.
Some do, and trading without registration is an offence. Under the Local Government (Miscellaneous Provisions) Act 1982, councils can require registration for acupuncture, tattooing, cosmetic piercing, semi permanent skin colouring including microblading, and electrolysis. Both you and the premises have to be registered, and the premises are inspected before it is granted, which means the therapy room itself gets inspected. Most hair and beauty work falls outside it, so a hairdresser, nail technician or beautician offering standard services usually has nothing to register. Adoption varies between councils, so check with yours, and tell us early if it applies so we build to the byelaw standards from the start.
In most cases, yes, and plenty of people already run a salon business from home this way. The question is scale rather than principle. Permitted development covers a garden building used incidentally to the house, and a single operator seeing a handful of clients a day generally sits inside that, so no planning permission is needed. Where it changes is when the property starts behaving like commercial premises, with cars arriving all day, staff who do not live there, signage at the gate and appointments running late into the evening. At that point, a council may treat running a business from home as a material change of use.
Choosing the right design for your double garage conversion in Bedfordshire starts with how you want to use the space day-to-day, then works backward to layout, light, heating and flow. A double garage gives enough area for open-plan living, a self-contained annexe, or multiple rooms such as an office and utility combined. Think about natural light, how the room connects to the rest of the house, storage and future flexibility as your needs change. Browse our garage conversion ideas, see recent conversions we have completed, and take a look through the gallery for inspiration. Call 01234 959502 to start planning.
Some double garage conversions in Bedfordshire do face council restrictions, so it is worth checking before you plan the room. Common restrictions include planning conditions on newer estates requiring the garage to stay available for parking, Article 4 directions that remove permitted development rights on certain streets, and tighter controls in conservation areas or on listed buildings. Where these apply, you may need a full planning application. Your local planning authority can confirm what applies to your address. We work across the areas we cover and can help you check your permitted development status before committing to a double garage conversion.
For most double garage conversions in Bedfordshire you will not need planning permission, but you will always need Building Regulations approval, submitted as a Building Notice or a Full Plans application. Planning permission becomes relevant if your home is listed, in a conservation area, subject to an Article 4 direction or a retained-parking condition, or if you are creating a self-contained annexe. A Lawful Development Certificate is optional but useful proof that your conversion was lawful when you come to sell. We help you identify exactly which approvals your project needs before work begins, with more answers on our FAQs page.
The best insulation type for a double garage conversion in Bedfordshire depends on the space you have and the U-values you need to hit, rather than one product suiting every job. Rigid PIR or polystyrene boards are popular for floors and walls because they achieve strong thermal performance in a slim thickness, which matters when floor height and internal space are tight. Mineral wool is often used between roof joists and for acoustic separation on party walls. The right choice balances thermal performance, moisture control and available space. We specify the full build-up for your double garage and confirm it with building control before installation.
Getting building control sign-off on a double garage conversion in Bedfordshire follows a clear sequence. First, submit a Building Notice or Full Plans application to your local building control authority. Next, the inspector visits at key stages during the build, checking things like foundations, damp-proofing, insulation and structural work before they are covered up. Once the conversion is complete and complies with the regulations, building control carries out a final inspection and issues a completion certificate. Keep that certificate safe, as buyers and solicitors will ask for it. We manage this whole process for you, and cover more common queries on our FAQs page.
Yes, a double garage is one of the best spaces in Bedfordshire to convert into a man cave, whether you want a home bar, cinema room, games room, or a mix of all three. Because it usually stays a habitable room within your home, planning permission is rarely needed, but Building Regulations still apply for insulation, electrics, ventilation and heating. The extra floor area of a double garage gives room for seating, a bar and separate entertainment zones. Our guide on converting a garage into a bar is a great starting point, and there are more garage conversion ideas to browse. Call 01234 959502 to talk through ideas.
To make sure your double garage conversion in Bedfordshire meets building standards, apply for Building Regulations approval before starting, use qualified trades, and book building control inspections at the right stages. Keep evidence such as photos of the insulation and damp-proof membrane, plus electrical and plumbing certificates, and arrange the final completion inspection to receive your certificate. The simplest way to stay compliant is to work with an experienced local builder who manages this for you. Our guide on choosing the right garage conversion company explains what to look for, and you can learn more about Pro Assist and how we work.
Double garage conversions in Bedfordshire usually fall under permitted development when the work is internal and the external appearance of the property is largely unchanged, meaning no planning application is needed. This is not guaranteed, though. Permitted development rights can be removed by an Article 4 direction, by planning conditions on newer estates that require the garage to stay available for parking, or where the property is listed or in a conservation area. Converting the garage into a separate dwelling also sits outside permitted development. We recommend confirming your status with the council, and can help you check, with more answers on our FAQs page.
A double garage conversion in Bedfordshire needs ventilation that meets Part F of the Building Regulations, which prevents damp and condensation in the new room. That usually means background ventilation such as trickle vents, openable windows for purge ventilation, and mechanical extract fans in any new bathroom or utility. Good ventilation works alongside damp-proofing to keep the converted space healthy and comfortable throughout the year. We design the ventilation strategy around your specific layout and how the room will be used, so the finished space feels like a proper part of the house rather than a cold, converted garage.
Foundations for a double garage conversion in Bedfordshire depend on the existing garage structure, because garage foundations are often shallower than those of the main house. Building Control will assess them and may require reinforcement where the loads change, for example when the garage door opening is infilled with a new load-bearing wall. Any new walls need adequate foundations tied into the existing structure. We check the foundations and structural details early, so there are no surprises once work is underway. If you are weighing your options, our guide on garage extension vs conversion explains the structural differences, and you can see the full scope of a double garage conversion here.
Yes. Double garage conversions in Bedfordshire require building control approval because you are turning a non-habitable space into a habitable room. You submit either a Building Notice or a Full Plans application to your local building control authority before starting. An inspector then checks the work at key stages, such as before the damp-proofing and insulation are covered up, and issues a completion certificate at the end. That certificate matters when you sell the house, as it proves the work was done properly. We arrange building control and coordinate the inspections on your behalf, and answer more questions like this on our FAQs page.
Electrical work in a double garage conversion in Bedfordshire must comply with Part P of the Building Regulations. New circuits, a replacement consumer unit, or any electrics in a new bathroom or shower room are notifiable, so they must be carried out or signed off by an electrician registered with a Competent Person Scheme. For a double garage you will typically plan sockets, lighting, heating and data points around how the room will be used, whether that is a home office, annexe, gym or family space. We handle the electrical design and certification as part of the conversion, so it is compliant and ready for building control sign-off.
A double garage conversion in Bedfordshire needs insulation to the floor, walls and roof to meet current Part L thermal standards, because garages were never designed to be warm or airtight. Typical published local authority targets are around a floor U-value of 0.25 W/m2K, walls near 0.28 W/m2K, and a pitched roof around 0.16 W/m2K, though your building control officer confirms the exact specification for your property. Single-skin garage walls usually need an insulated inner skin or a timber-framed panel, and all insulation should be linked together to avoid cold spots and thermal bridging. We agree the full insulation build-up with you before work begins.
Converting a double garage into a granny flat in Bedfordshire usually means creating a self-contained annexe with its own living space, bathroom and kitchenette, so planning permission is more likely to be needed than for a simple room conversion. The process runs: confirm the planning position with the council, design the layout, apply for Building Regulations approval, then complete the build with insulation, damp-proofing, heating, ventilation, electrics and compliant drainage. A double garage gives enough floor area for a comfortable, independent space for a relative. See a real example in our self-contained annexe project, or explore detached garage conversions if the annexe is separate from the house.
Choose a double garage conversion contractor near Bedfordshire who is properly accredited, communicates clearly, and manages the whole project rather than leaving you to coordinate trades. Look for insurance, genuine Building Regulations experience, and real local reviews. Pro Assist Property Services is CHAS accredited, a Federation of Master Builders member, and Trading Standards approved, with more than 50 garage conversions completed across Bedford and the surrounding area. Homeowners repeatedly tell us they valued not having to chase updates and feeling comfortable having the team in the house. Read our guide on choosing the right garage conversion company, learn more about Pro Assist, or get in touch to talk it through.
In most cases you do not need planning permission for a double garage conversion in Bedfordshire, because the work is usually internal and falls under permitted development. Permission can be required if your home is listed, sits in a conservation area, has a planning condition requiring the garage to stay as parking (common on newer estates), or if you are creating a separate dwelling such as a self-contained annexe. Some streets also have permitted development rights removed through an Article 4 direction. It is worth confirming your position with your local planning authority or applying for a Lawful Development Certificate. We cover this in our common questions before converting guide, and can help you check before any double garage conversion work starts.
Double garage conversions in Bedfordshire always need Building Regulations approval, even when planning permission is not required. Building Control look at structural safety when the garage door is removed and infilled, thermal insulation to the floor, walls and roof (Part L), ventilation (Part F), electrical work (Part P), damp-proofing and moisture control (Part C), fire safety, and drainage if you add a bathroom or utility (Part G and H). An inspector visits at key stages and issues a completion certificate once the work complies. We build every conversion to these standards and arrange the inspections for you, and you can read more in our guide to the common questions homeowners ask before converting.
The best way to convert a double garage into a living space in Bedfordshire is to plan around how your family actually lives, then work with a builder who manages the whole process for you. Because a double garage gives you more floor area, you can create an open-plan family room, a self-contained annexe, or split the space into a home office and utility. Start by checking whether the floor needs raising to match the house, confirm the insulation and damp-proofing strategy, and agree the layout before work begins.

Yes, a single garage is comfortably large enough for a home office or a bedroom. A typical UK single garage is around 2.4 to 3 metres wide and 5 to 6 metres long, giving roughly 13 to 18 square metres of internal space once it is lined and insulated, which is similar to or larger than many existing bedrooms. That is ample for a desk, storage and a meeting setup in an office, or a single or double bed with wardrobes in a bedroom. The main thing to plan for is the slight loss of width and length from the insulated wall and floor build up, which we design around to protect usable space. See layout ideas on our garage conversion ideas page, or how we approach rooms on our single garage conversion service.
Yes. A single garage conversion is already one of the more affordable ways to add a room around Bedfordshire, because you are reusing the existing floor, walls and roof instead of paying for new foundations and an extension. Costs can be kept sensible by choosing a simple layout, avoiding plumbing where you can, keeping the existing window and door positions, and using practical finishes. The one place not to economise is the essentials, insulation, damp proofing and electrics, since cutting those fails building control and costs more to put right later. We will help you plan a build that fits your budget and still passes inspection first time. Start with our cost guide and some garage conversion ideas to see what is achievable.
Yes, it can, so it is worth telling your insurer at two points. Before work starts, notify your home insurance provider, because major building works are usually excluded from a standard policy and can affect your cover while the house is a building site; you may need cover for the works, and your builder should carry their own public liability insurance. Once the playroom is finished, tell your insurer again, because the extra habitable room raises your home’s rebuild value, which can nudge the premium up. Keeping the building control completion certificate matters too, as insurers may query claims on conversions that were never signed off. We work to full building regulations and provide the paperwork. For ideas, see our garage playroom guide, or arrange a free consultation.
Getting a quote for a single garage conversion with us starts with a free, no obligation consultation, available within roughly 30 miles of Bedford. We visit your home, look at the garage’s floor, walls, damp and access, talk through how you want to use the room, then put together a clear, itemised quote with no hidden fees, so you can see what each part of the work costs rather than a single lump sum. There is no pressure to proceed. You can request yours through our contact page, or call the team directly, and we will arrange a convenient time. More about what is included is on our single garage conversion page.
Yes, that is exactly what we do. A single garage conversion is one of the most practical ways to gain extra living space in Bedfordshire without the cost and upheaval of moving, and it lets you stay in the home, street and school catchment you already like. Moving easily runs to several thousand pounds in fees, stamp duty and removals before you gain a single room, whereas a conversion reinvests that money into your own home. We turn underused single garages into bedrooms, offices, snugs, playrooms and utility rooms, fully managed from first idea to final finish. Our guide to extension vs conversion weighs the options, and you can start with a free consultation for our single garage conversion service.
A typical single garage conversion in Bedfordshire takes around 2 to 5 weeks on site, which makes it one of the quicker ways to add a room as your family grows. A straightforward bedroom, playroom or living space sits at the shorter end; adding a kitchen, shower room or extra structural work extends it, and plaster and screed need drying time before the final finishes go in. Before we start, we give you a clear, stage by stage schedule so you can plan around school runs and daily routines, and we keep the home livable throughout. Book a free consultation for a timeline on your home, or see how we work on our single garage conversion page.
Converting a single garage into a bedroom in Bedfordshire always needs building regulations approval, with a few requirements specific to sleeping rooms. Under Part B fire safety, the bedroom needs a means of escape window with a clear opening of at least 450mm by 733mm, no more than 1.1m above the floor, plus a mains-linked smoke alarm. Alongside that, Part L covers insulation to current U-value targets, Part C the damp proof membrane and moisture control, Part F ventilation, and Part P the electrics. The old door opening is usually infilled with a load bearing wall and window. We manage the full building control process within our single garage conversion service, and our homeowner questions guide covers the common queries.
It can, and in most cases, it improves your property value rather than harming it. Swapping a garage that mostly stored clutter for a warm, usable room is a trade most Bedfordshire buyers welcome, and a well-finished single garage conversion commonly adds around 10% to 20% to a home’s value. The value only tends to suffer in two situations: where off street parking is genuinely scarce and the garage was being used for a car, or where the work was done without building control sign off, which makes the room legally unfit to live in. We focus on a finish that reads as a natural room and is properly certified. Our cost guide explains the likely uplift, and our single garage conversion service includes the finish.
For most homes near Bedfordshire, converting an attached or integral single garage into a bedroom does not need planning permission, because the work is internal, keeps the building the same size and stays part of a single family home, which falls under permitted development. You will always need building regulations approval, and for a bedroom that includes a means of escape window and a mains linked smoke alarm. Planning permission is required if your home is listed, in a conservation area, under an Article 4 direction, or if your estate has a condition keeping the garage for parking. A detached garage converted to a bedroom can also need permission. We confirm exactly what applies before any garage conversion starts, which you can arrange at a free consultation.
Realistically, a single garage conversion in Bedfordshire usually costs somewhere between £8,000 and £20,000, with a straightforward living room or office often landing around £12,000 to £15,000 for roughly 15 square metres. The figure rises when you add plumbing, a kitchen or a shower room, and falls with a simpler specification. The biggest variables are the floor and damp proofing, the level of insulation needed to meet building regulations, and whether the structure needs reinforcing where the door was. We give a clear, itemised quote rather than a vague lump sum, so you can see what each element costs. Our garage conversion cost guide breaks down the factors, and a free consultation gives you a precise figure for your garage.
Any building work causes some disruption, but our process is designed around homes that are still being lived in. We keep communication clear, work tidily, and manage the project in a controlled way so that daily life can continue as normally as possible.
Yes. A site survey helps us check the structure, access, layout, and any details that could affect the final quote. It also gives you a chance to ask questions before committing to the project.
Yes. Our conversions include insulation to Building Regulation standards. Heating options such as electric heaters, underfloor heating, or air conditioning with heat and cool settings can also be discussed, depending on how you want to use the room.
Yes. Bathroom, kitchen, and utility room installations can be added to your conversion. These are priced separately because they depend on plumbing, drainage, layout, and the finish you want.
Yes. A double garage can often be converted into one large room or divided into separate spaces, such as an office and utility room, gym and storage area, or family room and shower room. We will advise what is practical based on your garage layout.
Yes. The prices on this page are shown as starting prices plus VAT.
Yes. The garage conversion calculator on this page can give you a more tailored guide based on your project. However, the most accurate quote will come after we assess the garage and understand exactly how you want to use the space.
Yes. A single-part garage conversion usually costs less because it involves minimal structural alterations and keeps the existing garage door in place. A full garage conversion involves more work, such as removing the garage door, installing foundations, building a new front wall, and fitting a new window or access point.
Our starting prices include the main building, insulation, electrical, and internal finishing work listed under each conversion type. Some items, such as bathrooms, kitchens, flooring, decorating, underfloor heating, internet points, and bifold doors, are treated as add-ons because they depend on the room’s final use.
Our garage conversion prices start from £8,500 + VAT for a single-part garage conversion, £12,000 + VAT for a single full garage conversion, and £16,000 + VAT for a double garage conversion. The final cost depends on the structure, layout, access, specification, and any add-ons you choose.

Yes. Older garages can often be converted successfully, although additional aspects of building work such as insulation, brick work repairs, roof upgrades, or property maintenance improvements may sometimes be required depending on the condition of the structure.
Yes. Many homeowners in Cranfield and surrounding areas choose to create self-contained accommodation with sleeping areas, bathrooms, and living space for guests, relatives, or flexible long-term use.
Most conversions fall under permitted development and do not require full planning permission. However, restrictions may apply depending on the property type, previous alterations, or conditions from the local planning office.
In many cases, yes. Because the existing structure is already in place, garage conversion cost is often lower than building a traditional extension. Garage conversions are one of the most cost-effective ways of expanding your living space without losing garden space or taking on a larger building project.
Yes. Many homeowners replace the original garage door with larger windows, patio doors, or bi-fold systems to improve natural light and create a more modern living environment. This can make a significant difference to both the appearance and functionality of the space.
Garage floors are usually upgraded, levelled, insulated, and prepared for final flooring finishes. Depending on the project requirements, we may also install underfloor insulation to improve comfort and energy efficiency.
Absolutely. Garage conversions have become one of the most popular alternatives to a loft conversion for homeowners working from home. Creating a dedicated office space away from the main living areas allows for a quieter and more productive environment.
In many cases, yes. During the site survey, we assess ceiling height, roof structure, and floor levels to determine the best way to create a compliant and comfortable living space. Some projects may also benefit from underfloor insulation or structural adjustments.
Yes. A professionally completed garage conversion should blend naturally with the existing property. We carefully match brick work, flooring, plastering, windows, doors, and interior finishes to ensure the new room feels fully connected to the rest of the home.
Yes. Many garage conversions include compact bathrooms, shower rooms, or utility spaces depending on the available layout and plumbing access. This is especially popular for annex spaces, guest accommodation, and home office conversions.
A successful garage conversion is designed around natural light, room flow, storage, and how the space will actually function day to day. Whether creating a home office, utility room, or additional bedroom, we focus on practical layouts that maximise comfort while maintaining a high quality of the finish throughout.
Yes. Many new builds in Cranfield and surrounding areas include integral garages that are ideal for conversion. However, some developments may have parking restrictions or conditions set by the local planning office, which we assess during the initial survey.
One of the most common mistakes is focusing only on appearance rather than the long-term comfort and usability of the room. A reputable garage conversion should include proper insulation, ventilation, lighting, heating, and careful planning around the roof, flooring, and layout to ensure the finished space feels like a genuine extension of the home.
In most cases, yes. Because the majority of the building work takes place within the existing garage structure, disruption to the main property is usually far lower than with a full house renovation or large extension project. Many homeowners in Cranfield choose garage conversions as a practical way of expanding your living space while avoiding major disruption to the rest of the home.

The 4-year rule relates to planning enforcement. If work has been completed without permission and remains in use for four years, it may become lawful.

A typical garage extension project may involve several professionals, including a builder, architect or designer, structural engineer, and building control inspector to ensure the work meets current building regulations.
The condition of your existing garage can affect the garage extension cost. If foundations, walls, or roofing need to be reinforced or rebuilt, the overall project cost may increase.
Most garage extension projects take between 6 and 12 weeks, depending on the size of the build and the work required. Planning permission, design work, and inspections from building control may also affect the timeline.
A garage extension can provide additional living space, improve the layout of your home, and increase the value of your home. Many homeowners use an extension garage to create larger kitchens, dining rooms, extra bedrooms, or home offices.
The 4-year rule relates to planning enforcement. If a garage conversion has been completed and used as a living space for four years without enforcement action from the local authority, it may become lawful. However, it is always best to follow the correct planning process and ensure the project complies with building regulations.
A budget of £40,000 can be enough for some garage extension projects, particularly smaller builds or simple layouts. However, larger or more complex extension garage designs that include plumbing, kitchens, or bathrooms may require a higher budget.
The garage extension cost depends on factors such as the size of the extension, foundations, insulation, roofing, and interior finishes. On average, extending an existing garage in the UK can cost between £20,000 and £50,000 or more, depending on the complexity of the build.
In many cases, you will need planning permission to build a garage extension, especially if the extension increases the footprint of your property or changes the appearance of the building. However, some projects may fall under permitted development depending on the size and design. Even if planning permission is not required, the work must still meet current building regulations and be approved by building control.
These must be resolved before conversion. Damp-proofing and ventilation upgrades will be required to meet building standards.

We can include soundproofing materials in walls and flooring to reduce noise between rooms, great for both nap times and noisy game sessions. Soft furnishings like rugs, curtains, and wall panels also help dampen sound. We’ll suggest options based on how your family plans to use the space.
In most cases, no. A garage-to-playroom conversion doesn’t usually require a reassessment, especially if you’re not increasing the footprint of your home. That said, if you’re making big changes, it’s worth checking with your local council and we’ll advise if we think it’s likely to come up.
Definitely. We build with flexibility in mind. While the space will feel like a proper room, it’s entirely possible to revert it back into a garage if needed though many buyers love having the extra family space, so you might not want to!
In most garages, yes. Some basic prep work is essential to make it warm and dry. We’ll assess the existing floor and advise if a damp-proof membrane or insulation is needed. In some cases, raising the floor slightly helps keep things level, warm and kid-friendly underfoot.
Often, yes. Many families choose electric panel heaters or portable air conditioners that don’t need big wiring changes. We can assess what’s needed for your specific setup, and where needed, our qualified electricians can discreetly install what’s needed to keep things safe and efficient.
Smart layout planning makes it totally possible. Think overhead shelving, under-bench drawers, and tall built-in cupboards along one wall. We can even section off part of the garage for storage while dedicating the rest to play, it’s all about making the space work for your family.

We handle this through building control, ensuring all work, including structure, insulation, and electrics is fully compliant and completed to a high standard.
It varies, but most conversions start from a few thousand. The size of the space, the kit you want, and the finishes you choose all play a part.
Yes, creating a dedicated, functional space like a utility room can make your property more appealing to future buyers. It’s a desirable feature that supports modern living, especially for families.
Absolutely. If you’d like to retain part of your garage for storage or other uses, you can design a layout that splits the space effectively. Whether it’s for bikes, tools, or seasonal items.
In most cases, planning permission isn’t required, especially if the work stays within the existing structure of your home. However, your conversion will still need to meet current building regulations, particularly in areas like electrical safety, insulation, and ventilation.
Yes. Pro-Assist exclusively uses energy-efficient systems and materials to ensure your new home addition is as warm and cosy as it is, as well as well-built and of high value. Depending on the garage’s existing energy efficiency, we may increase the garage’s insulation, identifying any openings to the outside.
We also install energy-efficient windows and doors, which further enhance thermal performance and reduce heat loss. Often, the new garage conversion becomes one of the warmest rooms in the house. Perfect for a home office or snug den.
Absolutely! Home additions like an extra bedroom, cosy den, home gym, home cinema, or serene home office are highly sought-after by buyers. Home offices, in particular, are fast becoming a home essential in the new remote work environment.
According to Check a Trade, garage conversion can add up to 20% to your home’s value – that’s a staggering increase. Such sudden rises in your home’s value are associated with bedrooms with en-suite bathrooms. However, even adding a home office or playroom can boost your property’s asking price by 10%.
The duration of a garage conversion project depends on the size of the garage, the complexity of the finish, and the scope of the work. Usually, it takes around 2 to 5 weeks from start to finish. However, the job can take longer to complete if extensive insulation is required, it’s a double garage, or the building isn’t compliant with existing regulations.
Planning permission isn’t usually required for a garage conversion – assuming the work is internal and does not enlarge the building. If you intend to convert the garage into a separate house or annexe, then planning permission is required.
We can advise on speaking to the local planning authority to find out the relevant details about garage conversions in Milton Keynes.
We also handle the relevant building regulations, ensuring the construction accords with regulations related to thermal performance, fire safety, ventilation, and more. See the LABC website for further details.
A garage conversion is the transformation of a previously unused garage into a functional living space, such as a bedroom, games room, gym, or annexe. Compared to traditional extensions, garage conversions are usually cheaper, quicker, and easier to carry out, thanks to the existing structure.
While you’ll forgo a covered parking space, for most people, it’s a worthwhile sacrifice due to the additional living space they will gain.
Transforming your garage into an extra room not only improved your living space but is also a more cost-effective option than building an extension or relocating.
