Site constraints 9

Listed building
Metropolitan Open Land
Green belt level protection inside London.
The London Plan gives Metropolitan Open Land the same protection as green belt: inappropriate development needs very special circumstances.
Air quality management area: Richmond AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
Council record ↗
SSSI 2 m away: Bushy Park and Home Park SSSI
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
Registered park or garden 2 m away: Bushy Park
Its setting is a consideration for work nearby.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Historic England ↗
Habitat network: Wood pasture and parkland
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Conservation area 2 m away: Bushy Park
The edge of the area; work outside it can still affect its setting.
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.
