Site constraints 4

Radon affected area, class 5
An estimated 10 to 30% of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.
From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.
UKHSA radon ↗
National park 26 m away: South Downs
Outside the park; its setting can still be raised.
Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.
Also on the record
Inside the Telscombe Cliffs built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 2, but it predates the buildings here and the current map does not class it as farmland.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site
