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

Do you need planning permission for a garage conversion in Hamilton?
The approval route for Hamilton is set by planning law in Scotland. In Scotland converting a garage usually does not need planning permission if the outside appearance barely changes, but a building warrant is needed before work starts.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
We check this for your address before design work starts, so there are no surprises later.
What we handle
On a typical garage conversion we handle:
- Electrics, heating and plastering
- New wall and window to replace the garage door
- Drawings and building control application
- Foundation check under the garage door opening
- Planning check for removed permitted development rights
- Floor raised with insulation and damp-proof membrane
How long does it take?
Expect 3 to 6 weeks on site. Allow time beforehand for drawings and approvals, usually 6 to 12 weeks.
