Exercise, Year Round
Most home gyms fail for the same three reasons. The garage is too cold to face in February. The spare room is too small for anything beyond dumbbells. And the shed at the bottom of the garden turns everything inside it rusty by the second winter.
A gym garden room solves all three, but only if it is built for the job. Training equipment is heavy, cardio kit is power hungry, and one person working hard puts a lot of moisture into a sealed room. None of that is a problem when the building is specified around it.
Pro Assist has built for homeowners across Bedfordshire, Hertfordshire and Buckinghamshire since 2018.

What our customers say
Set Up For The Way You Actually Train
The building changes depending on what happens inside it. We start by asking what you own, what you plan to buy, and what a normal session looks like.
Why Homeowners Trust Us With The Build
Anyone can put an insulated box in a garden. What we do differently is worry about the parts you would only discover eighteen months in.
Some Of The Areas We Cover
Frequently asked questions.
Our most frequently asked questions.
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 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.
Yes, a detached garage can absolutely be converted into a playroom! The main things to consider are access (especially in colder months), insulation, and connecting power safely. We’ll help you plan for all of that — from heating to lighting — so it feels just as comfortable and inviting as a room in the main house.
Most garages are. We’ll check everything over and give honest, professional advice so you know what’s possible.
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.
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.
