FAQs

Do you assist with planning permission and Building Control compliance for extensions?

Yes. We work closely with structural engineers, architects, and local authority Building Control inspectors to ensure all extension builds meet current UK Building Regulations, thermal efficiency requirements, and structural safety codes.

Absolutely. As specialist carpentry and main building contractors, we manage the entire build lifecycle—from groundworks, brickwork, and structural steel installation to internal acoustic floors, plasterboard partitions, fire doors, and final timber joinery.

Project timelines vary depending on structural complexity and size. However, a standard single-storey side or rear extension generally takes between 8 to 14 weeks from ground excavation to complete second-fix internal hand-over.
