What goes into a garage conversion?
A garage conversion turns an attached, integral or detached garage into a habitable room by infilling the door opening, insulating the floor, walls and roof, and adding windows, heating and power. It is one of the quickest and cheapest ways to add a room.
- Planning and building control applications to the council
- Insulated floor, walls and ceiling
- Plastering, skirting and decoration-ready finish

Do you need permission for a garage conversion in County Londonderry?
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.

- Some new-build estates have a planning condition keeping garages for parking.
