Do you need planning permission for a bungalow rear extension in Bangor?
Whether your bungalow rear extension in Bangor needs a planning application depends on its size, your house and any local restrictions.
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. 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 Bangor like to extend?
Semis and detached houses are typical of Bangor, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ
Bungalow rear extension questions in Bangor
Do I need a party wall agreement?
Northern Ireland has no Party Wall Act; we agree any shared-wall work with your neighbour in writing.
Do you handle building control in Bangor?
Yes. We apply to the council's building control team and hand over the completion certificate.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
What postcode areas do you cover around Bangor?
Including BT19 and BT20, and the surrounding County Down area.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you match the brick or stone on my Bangor house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
