Do you need planning permission for a terraced house rear extension in Dundonald?

The planning route for a terraced house rear extension in Dundonald is set by Northern Ireland's householder rules and your council.

In Northern Ireland the Planning (General Permitted Development) Order (Northern Ireland) 2015 allows a single-storey rear extension of up to 3 metres on an attached house or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres within 2 metres of a boundary. Building control approval from the council is still required.

Northern Ireland has no Party Wall Act. Shared-wall work relies on agreement with your neighbour and the general law, so we put access and protection arrangements in writing before starting.

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 Dundonald like to extend?
