What is a porch?
A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.

Do you need planning permission for a porch in County Down?
Here is how the rules work for a porch in Northern Ireland. In Northern Ireland a porch is permitted development if its ground area is no more than 3 square metres, it is no higher than 3 metres (3.5 metres with a pitched roof) and it is at least 2 metres from a boundary with a road.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
