Higher Green and a large part of Longdown Lane North were designated as a conservation area in 2000. There are restrictions on buildings, extensions, roofs, windows, doors, hard standing, gates and fences in the conservation area.
The conservation was almost exclusively developed from the late 1920s onwards by Ernest Harwood, a local builder, who chose a pleasing vernacular style for his new houses. The houses retain elements taken from the historic buildings of Surrey with steeply pitched tiled roofs, tiled and timber-framed decoration, leaded light windows, and a variety of front doors and porches.
