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.

In Warwick, a garage conversion typically costs £17,500–£29,000 for a single integral garage, including VAT at 20% (standard rate). Prices in the West Midlands sit near the national average for this kind of work, and the range for Warwick reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Warwick?
Here is how the rules work for a garage conversion 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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
On a typical garage conversion we handle:
- Drawings and building control application
- Electrics, heating and plastering
- Wall and ceiling insulation
- Planning check for removed permitted development rights
- Building control completion
- Floor raised with insulation and damp-proof membrane
How long does it take?
The build itself usually takes 3 to 6 weeks on site. Allow time beforehand for drawings and approvals, usually 6 to 12 weeks.
