How much does a home extension cost in Truro?

In Truro, a home extension typically costs between £20,000–£70,000, depending on the project. South West costs are broadly around the national average — Cornwall labour and materials are a real factor. The biggest cost drivers are single vs double storey and floor area, foundations and structural work, and 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.
