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.

Do you need planning permission for a garage conversion in Dungannon?
Here is how the rules work for a garage conversion in Northern Ireland. In Northern Ireland a garage conversion usually does not need planning permission if permitted development rights apply, but building control approval is needed.
In Northern Ireland building control approval comes from the council, usually through a full plans application or a building notice, with inspections during the work and a completion certificate at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
From survey to sign-off, the job normally involves:
- Foundation check under the garage door opening
- Building control completion
- Floor raised with insulation and damp-proof membrane
- Planning check for removed permitted development rights
- Electrics, heating and plastering
- Wall and ceiling insulation
How long does it take?
The build itself usually takes 3 to 6 weeks on site. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.
