Builders in Bookham for Extensions, Lofts & Refurbishment
Design and build for homes and commercial premises in Bookham, KT23. One team and one point of contact from the first drawing to handover.

Building work in Bookham
London Design & Construction designs and builds extensions, loft conversions and refurbishments in Bookham. Homes here are mostly detached houses and bungalows on generous plots in Great Bookham and Little Bookham, and most of the work we are asked for is full-width rear extensions to detached houses.
Bookham is bordered by Metropolitan Green Belt, where extensions and replacement houses are judged against the size of the original building. Planning applications and building control are handled by Mole Valley District Council.
We built a full-width glazed extension to a detached house in Bookham between May 2025 and February 2026, and the project diary is on this site.

Frequently asked questions
Which parts of Bookham do you cover?
We cover the whole of Bookham (KT23), including the streets around Bookham Common and Polesden Lacey. We also work in Leatherhead, Cobham and Epsom, all within 10 km.
Do I need planning permission for an extension or loft conversion in Bookham?
It depends on the plot. In the Green Belt around Bookham, an extension must not be disproportionate to the original house, so the size of the existing building and any earlier extensions matter. Houses within the built-up area can often still use permitted development. Mole Valley District Council decides applications, and we check the planning history before designing.
What kind of building work do you carry out in Bookham?
Most of the work in Bookham is full-width rear extensions to detached houses. The typical properties are detached houses and bungalows on generous plots in Great Bookham and Little Bookham. 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 Bookham?
Mole Valley District 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 Bookham?
Yes. Our project diary for a detached house in Bookham shows a full-width glazed extension from the dig-out in May 2025 to handover in February 2026.
