How much does a home extension cost in Southampton?
In Southampton, a home extension typically costs between £20,000–£70,000, depending on the project. The biggest factors 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.
