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

Planning for a bungalow rear extension in Dundonald follows the Northern Irish householder rules.

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 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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application.

What are homes in Dundonald like to extend?

Dundonald has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
