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.

Do you need planning permission for a garage conversion in Maidstone?
Before anything is built in Maidstone, we confirm which approvals apply in England. In England converting an integral or attached garage usually does not need planning permission, unless a condition on the house removed permitted development rights (common on estates built in recent decades) or the house is listed. Building regulations approval is always needed.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Planning check for removed permitted development rights
- Wall and ceiling insulation
- Drawings and building control application
- Electrics, heating and plastering
- New wall and window to replace the garage door
- Foundation check under the garage door opening
How long does it take?
Allow 3 to 6 weeks on site. Allow time beforehand for drawings and approvals, usually 6 to 12 weeks.
