A lawful development certificate is not compulsory for permitted development, but it is the cleanest proof that the extension was lawful when you come to sell. We usually recommend one.
Local to Coleraine
Site visits are available across Coleraine (BT52). Neighbouring towns we cover include Limavady (13 miles), Magherafelt (26 miles), Derry/Londonderry (27 miles).
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 Coleraine
In Northern Ireland we check the permitted development limits for your house type and, where needed, apply to your council for planning permission, then submit full plans or a building notice to council building control.
The planning position for a specific Coleraine address depends on its history and any designations, which is why we check it at the first visit.
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.
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.

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Questions answered
Do I need building regulations approval in Coleraine?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Coleraine, 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 long does this take for a Coleraine home?
8–13 weeks typical decision period, depending on the council and the complexity of the project.
What happens if planning is refused?
You can revise the design and reapply, or appeal. We read the officer’s report and tell you honestly which option has a better chance.
