A cost-effective way to add living space without extending your footprint. Popular for home offices, bedrooms and playrooms.
Thermal performance, ventilation and fire escape requirements are covered as part of our managed Building Control process.
The challenge
Garage conversions look straightforward. In practice, these are the issues homeowners hit when the job isn't managed properly.
Garage slabs sit below house floor level. Without proper damp proofing, insulation and ventilation, converted space becomes cold, musty and unusable.
Fire separation, escape routes, thermal standards and electrical certification are not optional. Cutting corners creates problems when you sell or remortgage.
Different floor levels, awkward door openings and visible joins make conversions feel like an afterthought rather than part of your home.
Converting without thinking about remaining storage, access or services leaves homeowners regretting the layout within months.
Electrician, plasterer, carpenter and builder coordinated separately means delays, gaps in quality and nobody accountable.
Our approach
We convert garages properly: surveyed first, documented throughout, signed off through Building Control.
We assess structure, floor levels, head height, services and damp conditions before quoting. No guesswork.
Insulation, damp proofing and ventilation designed to current standards so the room performs like the rest of your home.
New openings, floor transitions and finishes tied in cleanly with existing rooms.
All submissions, inspections and completion certificates handled as part of our service.
Electrics, plastering, heating, flooring and decoration under one programme and one point of contact.
Why choose us
Why garage conversions are one of our most popular projects across Milton Keynes and surrounding areas.
Extension types
Attached to the main house. Often the most cost-effective way to add a bedroom or office.
Separate structure converted for annex, gym or studio use with full services.
Extra sleeping space without extending your footprint.
Quiet, insulated workspace separated from the main house.
Self-contained living with bathroom and kitchenette options.
Our system
We visit your property, assess feasibility, take measurements and discuss your goals in detail.
A clear scope of works with programme, specifications and transparent pricing — no pressure to proceed.
Contracts, specifications and payment stages agreed before any work begins.
Your project manager coordinates all trades, materials and inspections throughout.
Completion survey, certificates and guarantees — plus an annual aftercare visit every year.
Quality control
Photographic survey documenting existing conditions, access routes and protection requirements before work starts.
Stage inspections at structural, first-fix and pre-plaster milestones — issues addressed before being covered up.
Completion survey confirming workmanship standards, testing results and snag-free handover.
We return every year for a complimentary aftercare inspection — checking the work, addressing minor touch-ups and giving you continued peace of mind long after completion.
Peace of mind
Regulations
Most garage conversions fall within Permitted Development if the footprint does not increase. Change of use rules and local constraints still apply.
Converting an existing garage to living space often qualifies as Permitted Development, provided you are not increasing the building footprint.
All garage conversions must meet Building Regulations for thermal performance, fire safety, ventilation and electrical safety.
Avoid costly errors
Learn from the errors we see homeowners make — so your project runs smoothly from day one.
Garage floors and walls often hold moisture. Converting without addressing this leads to expensive remedial work later.
Minimum comfortable ceiling height matters. We assess structure and floor build-up at survey.
Garage circuits rarely suit living space loads. Consumer unit upgrades are often required.
Unregistered work causes problems on sale. We coordinate sign-off before handover.
Use our Project Planner for a realistic guide price, or read our detailed cost guide — then book a free survey for a fixed quotation.
The internal space converts to living area. If you need to retain parking, we can discuss partial conversions or alternative layouts at survey.
Most garage conversions are permitted development, but change of use rules apply if the property is in a conservation area or has restrictions. We verify this at survey.
A well-executed conversion typically adds 10–20% to usable floor space. We focus on quality that adds genuine long-term value.

Customer Completion Gift
A small thank you for choosing us.
A fantastic job done on my property by Kyle and team. Highly recommend them for all roofing and guttering jobs. Also would like to add the great communication from start to finish. Thank you!
Kyle and the team did a great job today of cleaning my garage roof from moss and then painting a polymer waterproof coating onto the roof. The manufacturers 10 year guarantee for a single layer makes it an easy choice for fixing water ingress into a garage. Time will tell, but I have high expectations. All the rubbish generated was taken away so very pleased.
Kyle and his team at Quality Roofing were great, punctual, communicative, and reasonably priced. They removed our old solar heating panel, replaced the felt and tiles underneath, and disposed of the panel, all in under 90 minutes. Great service from a reliable team.
Kyle arrived quickly to look at a problem we had with an old Velux. He quickly set about repairing it and it is now working fine. We really appreciate his quick service. Highly recommended.
