Chilterns 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.
Little Gaddesden 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 1
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
