Overview
The fastest, cheapest way to add a real room
A garage conversion uses the foundations, walls and roof you already own. That alone removes 40–60% of the cost of an extension. The result is a fully habitable, insulated, heated room that meets every Building Regulation — typically delivered in 4–6 weeks.
Done well, the converted garage looks like it was always part of the original house from the outside. No obvious 'bolted-on' brickwork. We match brick courses, render textures and roof lines so it reads as one continuous elevation.
Who it's for
Home workers, growing families, multi-generational households, and anyone with a garage that hasn't held a car since they bought the house.
When you need it
When you need an extra room urgently, when budgets won't stretch to a full extension, or when planning constraints rule out building outwards.
Why use a professional
Garages were not built to habitable standards. Floors, walls, roof, drainage and ventilation all need upgrading to pass Building Control. DIY conversions almost always fail at sale.
Why It Matters
What goes wrong with a botched garage conversion
Buyers' surveyors spot bad garage conversions instantly. Here are the issues we get called to fix.
RISK 01
Floor below DPC level
Original garage floors are typically 100–150mm lower than the house floor. Without raising and insulating, you get cold feet, condensation and rising damp.
RISK 02
No cavity in the up-and-over wall
Bricked-up garage doors with no cavity wall are a damp bridge waiting to happen. We rebuild as a full insulated cavity.
RISK 03
Inadequate insulation
Single-skin garage walls fail Part L by a wide margin. We line internally with 70–100mm PIR plus plasterboard to bring U-values inside Building Regs.
RISK 04
No Building Control sign-off
Without the completion certificate the room remains officially a garage. At sale, the buyer's solicitor will require indemnity insurance — and may renegotiate the price downwards.
RISK 05
Boiler still in the room
Boilers can stay in a habitable room only if properly enclosed and ventilated. We either box them in to Gas Safe standards or relocate them to the loft.

In Detail
Conversion specifications and use cases
Different end-uses change the spec. Here's what we recommend for the most common requests.
Snug or playroom
Underfloor heating on insulated screed, soft acoustic ceiling, flush internal door to keep the room visually connected to the rest of the home.
Gym conversions
Reinforced floor build-up to take rubber tiles and free weights, mechanical extract ventilation, full-height mirrors, dedicated 32A circuit for treadmills and rowers.
Granny annexe / guest suite
En-suite shower room, kitchenette point, separate external door if access permits, sound-rated partition wall to the main house.
Front-of-house elevations
Where the garage door faces the street we either replace with a brick infill (matched mortar) or install a large fixed picture window for daylight without the 'bricked-up' look.
Heating integration
We tie the new room into the existing wet heating system with a dedicated zone and thermostat. For larger conversions we may upgrade the boiler — we'll tell you upfront.
Floor build-up
From the slab up: DPM, 100mm PIR, 65mm screed (with UFH pipes if specified), then engineered timber, LVT or carpet. Final finish floor matches house floor level.
Detached garage conversions
Detached garages can also be converted but trigger additional Building Regs around fire separation and may require planning if used as living accommodation. We advise on a case-by-case basis.
