Garage conversions done properly, from the first survey to the completion certificate
Most garages never see a car. They fill up with boxes and bikes while the family runs out of room inside. Converting the garage gives you a proper, warm, fully finished room without an extension and without moving. We keep things simple by focusing on the four rooms people want most: a bedroom, a living room, a home office or a gym.
Every job starts with a free survey and ends with a Building Regulations completion certificate. Where the work changes the structure, such as taking out the garage door and building the new wall, knocking through to the house or fitting a steel beam, we appoint a structural engineer and the Building Control inspector and deal with both on your behalf. You get one point of contact and one fixed price.
How a garage conversion works
Four stages from the first phone call to handing over the keys to your new room.
- 1
Free survey and fixed-price quote
We visit, measure the garage, check the floor, walls, roof and damp, and talk through how you want to use the room. You get an itemised fixed-price quote, usually within a few days.
- 2
Design, engineer and Building Control
We draw the layout, bring in a structural engineer for any beams or openings, and submit the Building Notice or full plans to your council's Building Control.
- 3
The build
Door out, new wall and window in, insulated floor, walls and ceiling, electrics, heating and plastering. A typical single garage takes two to three weeks on site.
- 4
Inspections, sign-off and handover
We book and attend every Building Control visit, finish the decoration and hand over your new room with its completion certificate.

Questions people ask
Do I need planning permission to convert my garage?
Usually not. Converting an attached or integral garage without changing the footprint is normally permitted development. There are exceptions, such as listed buildings, conservation areas, newer estates where permitted development rights have been removed, and detached garages. We check with your council before any work starts.
Do garage conversions need Building Regulations approval?
Yes, every garage conversion does. Building Control checks the structure, damp-proofing, insulation, ventilation, fire safety and electrics. We submit the application, book and attend each inspection and hand you the completion certificate at the end.
Who arranges the structural engineer?
We do. Removing the garage door and forming the new wall, knocking through to the house or fitting a steel beam all need an engineer's design. We appoint the engineer, send the calculations to Building Control and build to the design.
How long does a garage conversion take?
A typical single garage takes two to three weeks on site. Knock-throughs, en-suites and larger garages take longer, and we agree a programme with you before we start.
How much does a garage conversion cost?
We quote after a free survey, because the price depends on the garage, the room you want and what the structure needs. Your quote is itemised and fixed, so you can see exactly what is included. Our cost guide explains what affects the price.
