Planning and approvals in Newtownabbey
In Northern Ireland the Planning (General Permitted Development) Order 2015 lets some single-storey rear extensions go ahead without planning permission, up to 3 m on a semi-detached or terraced house and 4 m on a detached house, within height and boundary limits. Larger, side and two-storey extensions normally need planning permission from the council, and building control approval is separate.
Homes in conservation areas, areas of townscape character and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
In Northern Ireland building control is run by the councils under the Building Regulations (Northern Ireland). We submit full plans or a building notice and book the inspections through to completion.
Northern Ireland has no Party Wall Act. Where work is on or close to a shared boundary, we agree access and protection with your neighbour in writing before work starts.
Applications are decided by your council, which handles local planning in Northern Ireland.

Questions people ask about wraparound extensions
Do you cover all of Newtownabbey?
Yes. We cover Newtownabbey and the surrounding parts of County Antrim. Site visits are free and there is no obligation.

Who do I contract with for a wraparound extension in Newtownabbey?

How much does a wraparound extension cost?
Our guide range is about £1,720 to £3,180 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £49,000 to £62,500 in Newtownabbey before design and council fees.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
