How much does a home extension cost in Chepstow?

A home extension in Chepstow usually falls in the £18,000–£62,500 range, though every project is different. Welsh building costs are usually below the UK average — Gwent labour and materials are a real factor. What you pay depends mainly on single vs double storey and floor area and foundations and structural work, plus planning, glazing and finish quality. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.

  • Check planning permission. Most larger projects need planning and building-regs approval — check early.

  • Set a clear budget. Allow a 10–15% contingency for unforeseen costs during the build.
