What to know before building in Sutton
Mostly interwar semis and detached houses, with older village centres at Cheam and Carshalton. Two-storey side extensions, wraparound kitchens, loft conversions and garden rooms.
Carshalton and Cheam villages are conservation areas; elsewhere the council looks at side gaps and roof design. We check your exact address with Sutton Council records before we draw anything, and price the whole job — design, approvals and build — in one estimate.
