Site constraints 5

Registered park or garden: St. Fagans Castle
Nationally designated heritage. Its significance and setting carry great weight.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
St. Fagans conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
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.
