Sloping ground on the greensand ridge
Reigate sits on the greensand ridge below the North Downs, and a large number of its gardens slope, sometimes steeply, away from or towards the house. A garden room on a slope needs a proper level platform and, quite often, retaining work either side of it - it is not simply a case of dropping a base on the lawn.
We survey levels first and design the platform and any retaining as part of the same job, so the room sits properly rather than perched.



Mature plots and established planting
Reigate's older residential streets have substantial mature gardens with established trees and hedging, which we work around carefully, protecting root zones during construction and siting the room to keep the best of what is already there.
- Level survey and retaining design on sloping plots
- Root protection for mature trees during groundworks
- Terrace and steps designed as part of the same build
