Common questions about single-storey home extensions in Northamptonshire
Got more questions?

Most single-storey rear extensions fall under Permitted Development Rights if they extend no more than 6 metres from the original house (8 metres for detached properties). However, if your extension exceeds these limits or your property has previous extensions, you'll need planning permission from West Northamptonshire or North Northamptonshire Council.
Most single-storey extensions take 4-8 weeks from groundworks to completion, depending on size and complexity. This includes excavation, foundations, brickwork, roofing, and finishing work. Weather conditions and any planning delays can extend this timeframe.
We handle the complete build from groundworks to handover, including excavation, concrete foundations, brickwork, roofing, and structural elements. Our in-house groundworks team manages drainage and site preparation, eliminating delays from coordinating multiple contractors.
Single-storey extensions typically range from £15,000-£25,000 for a standard rear extension, depending on size, materials, and ground conditions. Complex groundworks, premium materials, or challenging access can increase costs. We provide detailed written quotes after a site survey.
All of our work is backed by a workmanship guarantee, and we only use trusted materials that meet British Standards.
From site preparation and drainage to concrete bases and footings, we provide reliable groundworks across Northamptonshire — built to last and ready for any project.
