Covering Limavady
Site visits are available across Limavady (BT49). We also work in nearby Coleraine (13 miles), Derry/Londonderry (15 miles), Magherafelt (23 miles).
For homes towards County Tyrone, Strabane is around 24 miles away. In Northern Ireland, extension projects follow the NI planning rules and council building control, which we account for from the first survey.

Planning rules that apply in Limavady
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 Limavady address depends on its history and any designations, which is why we check it at the first visit.
Building close to a public sewer needs the agreement of NI Water, which we check during design.
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.

Common questions in Limavady
Do you cover all of Limavady?
Yes. We cover Limavady and the surrounding parts of County Londonderry. Site visits are free and there is no obligation.
Will my neighbours in Limavady 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.
Do I need building regulations approval in Limavady?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
How much does a side return extension cost?
Our guide range is about £1,810 to £3,270 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £22,500 to £28,500 at standard spec in Limavady, more in London.
