Site constraints 9

Grade II listed: 24-34, Thorngate
List entry 1282559 · 4 m away · 22 more listed buildings within 150 m (1 Grade II*, 21 Grade II)
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.
Show the other 22 with distances
Historic England ↗
Nutrient neutrality catchment: Teesmouth and Cleveland Coast SPA/Ramsar
New homes and overnight accommodation must show nutrient neutrality before approval.
Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.
Barnard Castle 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.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
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.

Also on the record
Scheduled monument 225 m away: Barnard Castle: ringwork, shell keep castle, chapel and dovecote; National infrastructure project 1725 m away: A66 Northern Trans-Pennine Project; Flood defence 24 m away (natural high ground, designed for a 1 in 2 year flood); Inside the Barnard Castle built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt
