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 Smethwick, a garage conversion typically costs £17,500–£29,000 for a single integral garage, including VAT at 20% (standard rate).

Do you need planning permission for a garage conversion in Smethwick?
Whether you need planning permission depends on your house and its location 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Planning check for removed permitted development rights
- New wall and window to replace the garage door
- Foundation check under the garage door opening
- Floor raised with insulation and damp-proof membrane
- Drawings and building control application
- Electrics, heating and plastering
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.

Questions about garage conversions in Smethwick
Do I need planning permission for a garage conversion?

Can the floor be level with the house?
Yes. The garage floor is raised and insulated to match the house floor level.
