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 Falmouth?
In Falmouth, a garage conversion typically costs £18,500–£30,500 for a single integral garage, including VAT at 20% (standard rate). Building costs in the South West are close to the UK average, so the figures for Falmouth are close to our national guide. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Falmouth?
Before anything is built in Falmouth, 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
