Working in Cookstown
Our survey diary covers Cookstown, including BT80. We also work in nearby 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.
The planning position for a specific Cookstown address depends on its history and any designations, which is why we check it at the first visit.
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.
Building close to a public sewer needs the agreement of NI Water, which we check during design.
Applications are decided by your council, which handles local planning in Northern Ireland.
What is included
- Single-storey extension options assessed first
- Structural survey before any upward extension
- Roof designs that tie into the existing hipped or gable roof
- Level thresholds and accessible layouts
- Planning application where needed
Bungalow roofs are often hipped, which makes tying in an extension roof a careful job. We draw the roof junction early because it drives both the look and the cost.

Common questions in Cookstown
Do I need building regulations approval in Cookstown?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
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.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,500 to £2,920 per m² including VAT. Going upwards is priced after a structural survey.
