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 Middleton?
In Middleton, a garage conversion typically costs £17,000–£28,000 for a single integral garage, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for the North West, where labour and materials are typically about 6% below average. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Middleton?
Before anything is built in Middleton, 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:
- Wall and ceiling insulation
- Planning check for removed permitted development rights
- Drawings and building control application
- Foundation check under the garage door opening
- Floor raised with insulation and damp-proof membrane
- Building control completion
How long does it take?
Allow 3 to 6 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.

Usually not if the work is internal and the house keeps its permitted development rights. Many newer houses have planning conditions that remove those rights, in which case an application is needed.

Yes. Converting a garage to a habitable room needs building control approval for insulation, ventilation, fire safety and the new wall.
Can a detached garage be converted?
Yes, but using it as separate living accommodation may need planning permission.
