How much does a home extension cost in Cambridge?
In Cambridge, a home extension typically costs between £21,000–£74,000, depending on the project. Costs in the East of England sit a touch above the national average, especially nearer London — Cambridgeshire 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.
Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.

Why a home extension makes sense in Cambridge
A home extension lets Cambridge families stay in the area they love while gaining the space they need. A well-built extension typically adds both significant living space and long-term property value.
Planning your home extension in Cambridge
The key to a smooth home extension is preparation — agree a clear written scope, understand the timeline, and make sure your installer is properly insured and qualified. Around Cambridge, we only introduce professionals who meet those standards.
Local know-how for Cambridge
Homes in and around Cambridge include historic college-city terraces, Fen-edge villages and brick farmhouses beside new estates. Those property types influence the best way to plan a home extension — low-lying fenland flood risk and city conservation areas both need factoring in. A local specialist who knows Cambridge will factor all of this into your quote and design.
