What is a garage conversion?
A garage conversion turns an integral or attached garage into habitable space, such as a study, playroom, bedroom or utility. The garage door is replaced with a wall and window, the floor is raised and insulated, and the walls and roof are brought up to building regulations.
How much does a garage conversion cost in Dyfed?
In Dyfed, a garage conversion typically costs £16,500–£27,500 for a single integral garage, including VAT at 20% (standard rate). That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Dyfed?
Here is how the rules work for a garage conversion in Wales. In Wales converting a garage usually does not need planning permission unless rights have been removed by a planning condition; building regulations approval is always needed.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
