Do you need planning permission for a kitchen-diner rear extension in Newtownards?
The planning route for a kitchen-diner rear extension in Newtownards is set by Northern Ireland's householder rules and your council.
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.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Newtownards like to extend?
Semis and detached houses are typical of Newtownards, and many have room for a rear extension within Northern Ireland's permitted development limits.
