What to know before building in Kingston upon Thames
Victorian and Edwardian villas and terraces in Surbiton and Kingston, and 1930s semis around New Malden and Tolworth. Rear and side extensions, loft conversions, and whole-house refurbishments of the larger Surbiton villas.
Surbiton and central Kingston have conservation areas, and riverside streets can fall within Thames flood zones. We check your exact address with the Royal Borough of Kingston upon Thames records before we draw anything, and price the whole job — design, approvals and build — in one estimate.
