Building in Chertsey
Chertsey and the surrounding KT16 postcode is our home ground. Our showroom and workshop are in Lyne, just off the B386 — you can drive past builds we've done locally on the way to enquire about your own. Addlestone (KT15), New Haw, Ottershaw and Row Town are all within a few minutes of our base and a regular part of our build schedule.
Planning Authority
Runnymede Borough Council
Covers the KT16 postcode area. Standard Surrey Permitted Development rules apply — most garden rooms don't need a planning application.
Thames / Flood Zone
Some Chertsey properties close to the Thames and the River Bourne are in Flood Zone 2. Our ground screw foundations allow natural water movement beneath the structure. We'd note any relevant flood risk considerations at the site visit.
AONB / National Park
Runnymede has significant Green Belt land — including around Thorpe, Longcross and some Chertsey fringe areas. Standard residential garden builds still fall under Permitted Development. We confirm at the site visit.
Showroom Visit

Common Questions About Garden Rooms in Chertsey
Do I need planning permission for a garden room in Chertsey?
Most garden rooms in Chertsey 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 Runnymede Borough Council. We assess your exact position at the free site visit — for the large majority of our Chertsey builds, no planning application is needed.
Can I visit The Green Rooms showroom in Chertsey?
Yes — and we'd encourage you to. Our showroom and workshop are in Lyne, just off the B386 near Chertsey. You can see cladding samples, glazing options, roof materials and construction details first-hand before committing to anything. It's the best way to understand the difference between our builds and cheaper alternatives. No appointment needed — call ahead and we'll make sure someone is available to show you around.
Are there any Green Belt restrictions near Chertsey?
Runnymede has significant Green Belt land — particularly around Thorpe, Longcross and the Chertsey fringe. Most standard residential garden builds still fall within Permitted Development even in the Green Belt: outbuildings are specifically exempted from the usual Green Belt restrictions on new buildings, as long as they're within the curtilage of an existing dwelling. We confirm the position for your specific plot at the site visit.
Will a garden room add value to my home in Chertsey?
Yes. A well-built garden room in Chertsey 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.
