Do you need planning permission for a glazed rear extension in Downpatrick?
Here is how the rules in Northern Ireland apply to a glazed rear extension in Downpatrick.
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.
Insulation and glazing follow Technical Booklet F1 in Northern Ireland, checked by council building control.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Downpatrick like to extend?
Downpatrick has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

Not if it is designed for its orientation, with solar-control glass, shading and ventilation.

Yes. We apply to the council's building control team and hand over the completion certificate.
