Kingston upon Thames, New Malden and Surbiton are owner-occupied, school-catchment family suburbs — 1930s semis, Edwardian terraces and riverside Victorian homes that are ideal for loft conversions and rear or side-return extensions. TrustBuilt Projects works across Kingston (KT1, KT2), New Malden (KT3) and Surbiton (KT5, KT6).
Kingston's housing is mostly 1930s semi-detached and Edwardian terraces, with riverside Victorian homes near the Thames and larger period houses around Coombe and Surbiton Hill. The everyday job here is a loft conversion paired with a rear or side-return extension on a family semi — adding bedrooms in the roof and an open-plan kitchen-diner below. Whole-house renovations are common on the older Surbiton and Kingston town stock. Conservation areas — Kingston Old Town, Surbiton Hill Park, Surbiton Town Centre, the Riverside North and South streets and Old Malden — call for a full planning application and careful detailing.
New Malden is home to the UK's largest Korean community and a broad East-Asian population — including Hong Kong and Chinese families — drawn by the schools and the owner-occupied family housing. A good share of our enquiries here come from those households planning lofts, extensions and whole-house renovations on the local semi and period stock.

Yes — Kingston upon Thames (KT1, KT2), New Malden (KT3) and Surbiton (KT5, KT6), plus Norbiton, Coombe, Old Malden, Berrylands and Tolworth.
A loft conversion paired with a rear or side-return extension. The loft adds bedrooms and an en-suite in the roof, while the extension opens the kitchen into a family dining space — the standard upgrade for a Kingston or New Malden family home.
Many lofts and rear extensions fall under permitted development. The borough's conservation areas — Kingston Old Town, Surbiton Hill Park, Surbiton Town Centre, Riverside North/South and Old Malden — and homes that have lost their PD rights need a full planning application. We advise on this at the free site visit.
