How much does a home extension cost in Wandsworth?

Plan for roughly £25,500–£89,500 for a home extension in Wandsworth, before any premium finishes. 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.
