What we deliver in Esher
Every street sits differently — a period terrace, a post-war semi, a modern infill. We shape the recommendation around your actual house, its planning context and how you want to live.
Esher's plots support substantial rear and double-storey extensions, orangeries and garden rooms — adding real space to already-large family homes.
Loft conversions add bedroom and en-suite space to Esher's houses, frequently combined with ground-floor remodelling.
Esher is strong new-build territory — replacement dwellings and bespoke homes on established plots, delivered end-to-end by one team.

Common Esher questions
Things you might need to know about building in Esher.
Do I need planning permission for an extension in Esher?
Many extensions in Esher fall under permitted development. Where a full application is needed, it goes to Elmbridge Borough Council — we assess your property type, the council's restrictions and any conservation status on the first visit, and handle the application ourselves.
How long does a project in Esher typically take?
From first consultation to handover: 6–9 months for a single-storey extension or loft, 9–14 months for double-storey or wrap-around. We give you a tighter estimate after the survey.
Are there conservation areas in Esher?
Several streets in Elmbridge Borough Council's area fall within conservation areas that restrict materials and detailing. We check your exact address against the register on the first visit, and we have approved schemes in conservation areas nearby.
What is a typical extension cost in Esher?
Build cost in this part of Surrey runs £2,500–£4,000 per square metre for a finished extension including kitchen and finishes. Our calculator gives a personalised estimate.
