Site constraints 8

World heritage site: Cornwall and West Devon Mining Landscape
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.
Historic England ↗
Public byway open to all traffic 11 m away
Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.
Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.
Priority habitat: Traditional orchard
A habitat of principal importance. It shapes the ecology work and the biodiversity net gain a scheme has to show.
Radon affected area, class 6
An estimated 30% or more 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 ↗
5 listed buildings within 150 m
Nearest: Fern Villa, Grade II, 39 m away · 5 Grade II
The site itself is not listed. Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.

Historic England ↗
Also on the record
Inside the St Agnes built-up area; Heritage coast 176 m away: St Agnes; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 3, 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 scheduled monument at the site
