Common questions
About extensions in Cambridge.
- How long does a typical extension take to build?
- Single-storey rear extensions of 25–40m² usually run 10–14 weeks on site, with 6–12 weeks of design and planning beforehand. Two-storey extensions add roughly four weeks to the build.
- Can you work on listed buildings or in conservation areas?
- Yes. A significant share of Cambridge sits within a conservation area, and we handle listed building consent, Article 4 directions, and conservation officer liaison routinely.
- How much does an extension in Cambridge cost?
- As of 2026, a well-built single-storey rear extension typically runs £2,800–£3,800 per m² including finishes. Glazing, structural complexity and listed status all push that range.
- Do you handle planning permission?
- Yes — drawings, planning portal submission, conservation and listed building consent, and any pre-application enquiries with Cambridge City or South Cambs.
