How much does a home extension cost in Thornbury?
A typical Thornbury home extension works out at about £20,000–£70,000 in 2025. South West costs are broadly around the national average — Gloucestershire 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.
Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.
