What we deliver in Cobham
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.
Cobham's bigger plots suit large single- and double-storey extensions, garden rooms and orangeries that add significant family space. We run the whole scheme with one in-house team.
Loft conversions add bedroom suites to Cobham's detached and semi-detached homes — often part of a wider whole-house remodel.
Cobham is prime new-build territory: replacement dwellings and bespoke homes on established plots, managed from feasibility to handover.

Common Cobham questions
Things you might need to know about building in Cobham.
Do I need planning permission for an extension in Cobham?
Many extensions in Cobham 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 Cobham 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 Cobham?
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 Cobham?
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.
