Covering Coleraine
Across BT52, we can visit, measure and advise. Nearby, we also take on projects in Limavady (13 miles), Magherafelt (26 miles), Derry/Londonderry (27 miles).
For homes towards County Antrim, Ballymena 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 and approvals in Coleraine
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
Included in a typical project
- Completion certificate on sign-off
- Structural calculations for beams, lintels and foundations
- Building regulations drawings and written specification
- Energy and glazing checks, including whole-house calculations if needed
- Inspection bookings throughout the build
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.

Common questions in Coleraine
Who do I contract with in Coleraine?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
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.
Do you cover all of Coleraine?
Yes. We cover Coleraine and the surrounding parts of County Londonderry. Site visits are free and there is no obligation.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
