Site constraints 9

Green belt: London
Inappropriate development needs very special circumstances.
Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.
Read the government guidance ↗
Kent Downs National Landscape
Great weight to conserving the landscape; major development restricted.
Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.
Sundridge 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.
Council document ↗
Habitat network: Network Expansion Zone
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
3 listed buildings within 150 m
Nearest: Bishops Court, Grade II, 61 m away · 3 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.
