Homes in County Antrim

Northern Ireland has a high proportion of detached houses and bungalows outside the cities, which often suit side extensions, rear extensions and upward extensions.

What goes into a garage conversion?

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.

What approvals does a garage conversion need in Northern Ireland?

In Northern Ireland the council handles both planning and building control. Permitted development rules are set by the Planning (General Permitted Development) Order (Northern Ireland) 2015, and there is no party wall act, so we agree access and protection with neighbours in writing.

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?

The garage floor is often lower than the house and needs raising.
A bedroom needs an escape window or a protected route out.
