Guest Accommodation Garden Rooms
The moment a garden building contains a bed, it loses the building regulations exemption. Not above a certain size. At any size. A modest room your mother stays in twice a month needs full approval, while the identical building used as an office does not.
That one rule reshapes the whole project. It sets the insulation standard, the ventilation, the fire detection, the escape window, the timeline and the cost. It is also why a garden bedroom is a construction job rather than a purchase, and why the paperwork at the end matters as much as the room itself.
We build them properly, with approval in place and a completion certificate at handover, so nothing surfaces awkwardly when you come to sell.

Who We Build Guest Garden Rooms For
Different guests need different buildings. The brief changes far more than the floor area does.
We build guest garden rooms for:
Guest Accommodation Garden Room Costs
It costs more than an office of the same size. The reasons are specific, and you should expect any builder to be able to name them:
- Full building regulations approval: drawings, submission, staged inspections and a completion certificate, all of which an exempt garden room avoids
- Fire safety provision: interlinked mains alarms, a compliant escape window, and fire resisting construction if you build near a boundary
- En suite drainage: a foul connection back to your existing drain, priced from where that drain actually runs rather than a guess
- Overnight thermal performance: a room that holds its warmth until morning, not one that has gone cold by three
- Ventilation designed for sleepers: two people asleep release far more moisture than one person at a desk
What Happens Once You Say Yes
Guest rooms take longer than a standard garden room, and almost all of that is approvals rather than construction. Knowing the shape of it upfront stops the wait feeling like a delay.
Why Choose Pro Assist For Your Guest Garden Room
A supplier delivers an insulated box on a lorry. A habitable room that satisfies a building inspector is a different discipline entirely.
- We handle building control, not you: the application, the drawings, every inspection stage and the certificate at the end are managed at our end
- Drainage and hot water are routine work here: we are a construction company, so the en suite is part of our build rather than a plumber you have to chase
- You get straight answers before you spend: including when the honest answer is that what you have described needs full planning permission
- Nothing needs chasing: you hear where the job is and what happens next without having to ring and ask
- The same team throughout: the people who quote your room are the people who build it and hand over the certificate
- Accredited and fully insured: Trading Standards vetted, CHAS accredited and FMB registered, with waste removed under our Environment Agency registration
- A build you can live alongside: predictable hours, a tidy site and a garden that stays usable, because your household carries on while we work
Frequently asked questions.
Our most frequently asked questions.
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.
