What do you get with a garage conversion?
A garage conversion turns an attached, integral or detached garage into a habitable room by infilling the door opening, insulating the floor, walls and roof, and adding windows, heating and power. It is one of the quickest and cheapest ways to add a room.
- Planning and building regulations checks under Welsh rules
- Building control application
- Insulated floor, walls and ceiling
What will a garage conversion cost?

| Single attached garage | £12,000 to £24,000 |

Do you need permission for a garage conversion in Cowbridge?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
In Wales, converting an attached garage usually does not need planning permission unless rights have been removed by condition or the building is listed.
What should I think about before starting?
- The garage floor is often lower than the house and needs raising.
- Losing a parking space can matter on streets with permit parking.
How does the project run?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
