How much does a home extension cost in Kingston upon Thames?

Homeowners in Kingston upon Thames usually spend in the region of £25,500–£89,500 on a home extension. London is the most expensive part of the UK for building work, well above the national average — Greater London 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.

How long does it take?

Plan for about 3–6 months of work for a home extension in Kingston upon Thames, weather and approvals permitting.

  • Match your materials. Choose brick and finishes that harmonise with your existing home.
  • Plan for the long term. Design for how you’ll use the space in five and ten years, not just now.
