Frequently Asked Questions

How much does a house extension in Godalming cost?

Costs vary by size, design, and specification. As a guide:

  • £1,800–£2,500 per m² for standard builds

  • £2,800+ per m² for high-spec finishes

We provide fixed pricing and can phase works to suit your budget.

Do I need planning permission in Godalming?

Many single-storey rear extensions fall under Permitted Development, but size, height and materials rules apply. We’ll confirm your options, manage any Redbridge Council planning submission (if needed), and handle building control approval.

How long does an extension take?

A typical single-storey rear extension takes 10–16 weeks on site, depending on scale, structure (e.g., steelwork), and finishes. Two-storey or wrap-around schemes will take longer. We’ll set out a clear programme before works begin.

Can you work in conservation areas or near the River Wey?

Yes. We consider character, materials, overlooking, and flood-risk constraints early, then design accordingly to smooth approvals and ensure a sensitive, durable build.

Will I need a Party Wall Agreement?

If your work is close to or on a shared boundary, the Party Wall etc. Act may apply. We’ll flag this early and guide you through notices and surveyor steps where required.
