What does a garage conversion involve?
Most integral garages already have the walls and roof; what they need is a new insulated floor, an infilled front wall with a window, and heating. We check whether your permitted development rights are intact, handle building control and finish the room ready to use.
- Planning check (some estates remove permitted development rights)
- Insulated floor, walls and ceiling
- Plastering, skirting and decoration-ready finish

Planning and building rules in Magherafelt
Projects in Northern Ireland need planning clearance from one of the eleven councils and building control approval, also from the council. The Party Wall etc. Act does not extend to Northern Ireland, so work near neighbours is agreed directly and documented carefully.
In Northern Ireland, garage conversions often do not need planning permission if the external changes are minor; building control approval is needed.
What can affect a garage conversion?
- Some new-build estates have a planning condition keeping garages for parking.
- Losing a parking space can matter on streets with permit parking.
