Builders in Epsom for Extensions, Lofts & Refurbishment
Design and build for homes and commercial premises in Epsom, KT17, KT18 and KT19. One team and one point of contact from the first drawing to handover.

Building work in Epsom
London Design & Construction designs and builds extensions, loft conversions and refurbishments in Epsom. Homes here are mostly Victorian and Edwardian houses near the town centre, inter-war semis towards Ewell, and larger houses near the Downs, and most of the work we are asked for is loft conversions and rear extensions to semis, and refurbishments of older houses near the town centre.
Epsom is a mix of ordinary residential streets and pockets of conservation area, so what can be built without a full planning application changes from one road to the next. Planning applications and building control are handled by Epsom and Ewell Borough Council.
The streets between the town centre and the Downs include several conservation areas, while the inter-war estates towards Ewell mostly have full permitted development rights.

Frequently asked questions
Which parts of Epsom do you cover?
We cover the whole of Epsom (KT17, KT18 and KT19), including the streets around Epsom Downs and Epsom Common. We also work in Leatherhead, Surbiton and New Malden, all within 8 km.
Do I need planning permission for an extension or loft conversion in Epsom?
It depends on the street. Outside the conservation areas, many rear extensions and loft conversions to houses in Epsom can be built under permitted development, and a lawful development certificate from Epsom and Ewell Borough Council confirms it. Inside a conservation area, or for a flat, a planning application is usually needed. We check which applies to your address first.
What kind of building work do you carry out in Epsom?
Most of the work in Epsom is loft conversions and rear extensions to semis, and refurbishments of older houses near the town centre. The typical properties are Victorian and Edwardian houses near the town centre, inter-war semis towards Ewell, and larger houses near the Downs. Each project has one point of contact, with design, structure, plumbing, electrics and roofing carried out by our own team.
Which council deals with planning and building control in Epsom?
Epsom and Ewell Borough Council. Where a project needs a planning application or a lawful development certificate, the drawings are prepared before work starts, and building control inspections are arranged at each stage of the build.
Can I see examples of your work near Epsom?
Yes. Our project diary for a detached house in Bookham, about 10 km from Epsom, shows a full-width glazed extension from the dig-out in May 2025 to handover in February 2026.
