Local knowledge
Building in Elmbridge
Elmbridge packs a lot of history into a small borough: Sandown Park racecourse in Esher, the landscape garden at Painshill Park in Cobham, and Brooklands in Weybridge, the birthplace of British motorsport and aviation. Across the river from East Molesey stands Hampton Court Palace, and the Thames frames the borough's northern edge.
Edwardian and 1930s homes in Thames Ditton, Molesey and Walton suit rear dormers and side return extensions, while larger detached houses in Weybridge, Cobham and Oxshott often call for double storey extensions and structural remodelling.

Questions
Building in Elmbridge: common questions
Do you cover Elmbridge and the surrounding area?
Yes. We work across Elmbridge, including Esher, Walton-on-Thames, Weybridge, Cobham, Molesey (East and West), covering the KT7, KT8, KT10, KT11, KT12, KT13, KT22 postcodes, and we serve homeowners across all Surrey postcodes.
Do I need planning permission for a loft conversion or extension in Elmbridge?
Many loft conversions and single storey rear extensions fall under permitted development, but conservation areas, flats and larger projects need planning permission. Applications for Elmbridge homes are decided by the local planning authority, currently Elmbridge Borough Council, and we prepare and submit everything on your behalf.
How much does a loft conversion or extension cost in Elmbridge?
We price every project after a survey, because the size, structure and finish of each home is different. When you appoint us, your agreed build cost is locked in, protecting you from unexpected costs during the build.
