What We Build in Cobham
Every garden room is designed around your space and your needs. All types are available in Cobham — fully turnkey, with a free site visit included.
Building in Cobham
Cobham has some of the most generous garden sizes in Elmbridge — particularly in the Fairmile and Stoke D'Abernon areas, where plots regularly exceed 0.25 acres. This gives us real scope for larger builds: golf simulator studios, extended-height bespoke rooms, and dual-use structures. Many Cobham builds are at the premium end of our range — Western Red Cedar, Charred Spruce, and bespoke proportions are the norm.
Nearby Project
Planning Authority
Elmbridge Borough Council
Covers the KT11 postcode area. Standard Surrey Permitted Development rules apply — most garden rooms don't need a planning application.
AONB / National Park
Cobham borders the Green Belt on several sides. Most residential plots still fall under Permitted Development for outbuildings — the Green Belt doesn't restrict what you build within your own garden curtilage as long as standard height and footprint rules are observed. We confirm at the site visit.

Common Questions About Garden Rooms in Cobham
Do I need planning permission for a garden room in Cobham?
Most garden rooms in Cobham fall under Permitted Development rights and don't require a planning application — as long as the structure is single storey, no taller than 2.5m within 2m of the boundary, covers less than half the original garden, and is not forward of the principal elevation. Your local planning authority is Elmbridge Borough Council. We assess your exact position at the free site visit — for the large majority of our Cobham builds, no planning application is needed.
How do I get a reliable internet connection to a garden office in Cobham?
The best solution is Cat 6a cable run in armoured conduit, trenched underground from your router to the garden office. We include this in our electrical scope — it's far more reliable than a Wi-Fi extender, and gives you a full gigabit connection regardless of how far the garden office is from the house. Most Cobham gardens are large enough that this trench run is 15–40m; we handle the full installation.
Are there any planning restrictions specific to Cobham I should know about?
Cobham is covered by Elmbridge Borough Council. The Fairmile and Oxshott fringe areas have some Green Belt land, but standard residential garden builds still fall under Permitted Development. Painshill Conservation Area is nearby but only affects properties directly within it. We check your specific address at the site visit before any design work begins.
Will a garden room add value to my home in Cobham?
Yes. A well-built garden room in Cobham typically adds between 5% and 15% to a property's value — and for premium builds in this market, the return can be greater still. Estate agents actively use garden offices and garden rooms as a headline selling feature. Beyond the financial return, a properly insulated, electrically certified structure transforms how you use your home all year round. See our reviews from customers across Surrey.
