Do you need planning permission for a side return extension in Newtownards?
Here is how the rules in Northern Ireland apply to a side return extension in Newtownards.
Northern Ireland's rules restrict side extensions more than rear ones, so a side infill or wraparound usually needs a planning application to the council as well as building control approval.
There is no Party Wall Act in Northern Ireland; we agree any work affecting a shared wall or boundary directly with the neighbour, in writing.
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?
Newtownards has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
