Extensions in and around Cookstown
Across BT80, we can visit, measure and advise. Nearby, we also take on projects in Omagh (22 miles), Strabane (30 miles).
Just over the County Londonderry border, Magherafelt is about 9 miles away. Northern Ireland's housing ranges from city terraces to large numbers of detached houses and bungalows on rural plots, many in render, where single-storey extensions fit easily.
Will the council need to approve it?
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.
In a conservation area or area of townscape character the permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition, any extension needs an application.
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.

Wraparound extension questions answered
Do you cover all of Cookstown?
Yes. We cover Cookstown and the surrounding parts of County Tyrone. Site visits are free and there is no obligation.
Will my neighbours in Cookstown be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Cookstown, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
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 Cookstown 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.
