Planning rules for Magherafelt

Northern Ireland's permitted development rules allow a single-storey rear extension of 3 metres on terraced and semi-detached houses and 4 metres on detached houses, with a 4 metre height limit. Listed buildings, conservation areas and houses with removed rights need planning permission from the council.

Northern Ireland has no larger-extension prior approval route; anything beyond permitted development needs a planning application.

In Northern Ireland building control is run by the councils. A rear extension needs approval (full plans or building notice) and is built to the Northern Ireland Technical Booklets.
