Do you need planning permission for a kitchen-diner rear extension in Downpatrick?
Whether your kitchen-diner rear extension in Downpatrick needs a planning application depends on its size, your house and any local restrictions.
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 Downpatrick like to extend?
Semis and detached houses are typical of Downpatrick, and many have room for a rear extension within Northern Ireland's permitted development limits.
