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 County Tyrone?
In County Tyrone, a garage conversion typically costs £15,500–£26,000 for a single integral garage, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for Northern Ireland, where labour and materials are typically about 14% below average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A single integral garage | £15,500–£26,000 |
| Higher specification | £26,000–£32,500 |
The biggest cost drivers are:
- Whether planning permission is needed
- Bathroom or kitchen
- Heating and flooring
- Foundations under the old door opening

Do you need planning permission for a garage conversion in County Tyrone?
Whether you need planning permission depends on your house and its location 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
On a typical garage conversion we handle:
- Wall and ceiling insulation
- Drawings and building control application
- Floor raised with insulation and damp-proof membrane
- Planning check for removed permitted development rights
- New wall and window to replace the garage door
- Foundation check under the garage door opening
How long does it take?
Build time is typically 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.
