Description
The Great Wall is a structure designed by Sir Edwin Lutyens, made of red brick. It consists of a long stretch of walling, partly featuring a pierced parapet, which extends from Hampstead Way to Heathgate. This wall serves as the garden boundary for several houses, each of which includes a garden house with a gazebo that overlooks the wall. The garden houses are partially weatherboarded, equipped with sliding sash windows, and topped with tiled pyramid roofs. Each garden has a door leading to the Heath Extension, with some doors set in tiled archways. Although the original plan was for the wall to continue to Wildwood Road, the eastern section was never constructed.
Local climate
The Great Wall sits in one of the driest parts of the UK, with an average of 690 mm of rain a year. This makes it drier than 98% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 98% of listed buildings.
It experiences an average of 30 freeze-thaw cycles a year, fewer than 66% of listed buildings. Of these, 13 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
