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 Portadown?
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.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
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:
- Building control completion
- Electrics, heating and plastering
- Planning check for removed permitted development rights
- Foundation check under the garage door opening
- Drawings and building control application
- New wall and window to replace the garage door
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.
