Do you need planning permission for a kitchen-diner rear extension in Newtownabbey?
The planning route for a kitchen-diner rear extension in Newtownabbey 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 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. 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 Newtownabbey like to extend?
Semis and detached houses are typical of Newtownabbey, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ
Kitchen-diner rear extension questions in Newtownabbey
What postcode areas do you cover around Newtownabbey?
Including BT36 and BT37, and the surrounding County Antrim area.
Do I need planning permission for a rear extension in Newtownabbey?
Often not for a single-storey rear extension of up to 3 metres (4 metres detached) under Northern Ireland's permitted development rules, outside conservation areas.
Can I have underfloor heating?
Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
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.
Do you handle building control in Newtownabbey?
Yes. We apply to the council's building control team and hand over the completion certificate.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
