Loft Conversions in Esher.
A loft conversion adds space without taking garden, which can suit Hinchley Wood, where most houses have already been extended to their side boundaries. Across Esher and Claygate, the larger detached and semi-detached houses can offer generous roof space to work with. A standard loft conversion, using rooflights, a dormer or a hip-to-gable change, usually takes 6 to 10 weeks, and a mansard 10 to 14 weeks.

Our focus in Esher.
The planning route depends on the roof and where the house is. Rooflights can often be added under Permitted Development, but dormers and hip-to-gable conversions are not Permitted Development in a conservation area, so in Esher, West End (Esher), Lakeside Drive, Claygate Village or Claygate Foley Estate they need a planning application. Elmbridge lists no Article 4 direction removing householder rights in Esher, Claygate or Hinchley Wood, so outside the conservation areas a rear dormer may be Permitted Development within its volume limits. A mansard normally needs planning permission. Any application includes the Elmbridge Design Code Checklist, and the route for your loft is confirmed before design starts.
As a design-and-build company we take on a limited number of projects at a time, so that every one gets the attention it deserves. If you are planning work on your Esher home, we would like to hear about it.

“Grand Innovations carried out our loft conversion and the experience was far smoother than expected for such a complex project. Conor was hands-on, knowledgeable, and always available when decisions needed to be made. The build quality is excellent. The stairs, insulation, carpentry, and finishes all feel high-end and carefully completed. What impressed us most was how well the different trades were managed and how much attention was paid to detail. The space now feels like it was always part of the house. A very professional team that takes real pride in their work.”
