A practical Cobham guide to your next garden room

Garden Rooms in Cobham is most of what we do. Cobham is dominated by large detached homes on the Fairmile, Stoke d'Abernon and Tilt Rd, with one of Surrey's highest household incomes and correspondingly substantial landscaping budgets. London clay subsoil demands engineered foundations on every garden room scope. For a garden room on a Cobham plot we usually plan around high water table plots where screw-pile foundations beat traditional concrete slabs, so the spec we quote is shaped by what actually goes wrong on this side of Surrey.

A teen den or annexe-style room with internet and a small kitchenette, relevant garden rooms detail for KT11 properties near Esher

The local brief behind the build

Cobham is inside our 30-mile core area, so site visits are arranged within a week and project supervision is daily, not weekly.
We've spent enough time on KT11 streets to know which ground conditions matter for a garden room - the Article 4 / conservation rules that affect permitted development on a small number of streets that gets missed when a national firm quotes from a desk.
Quotes are written, fixed and broken down by stage, with the same crew on site from day one through to clean-down.
