About the Old Deer Park Conservation Area
The Old Deer Park Conservation Area covers about 152 hectares and was designated by London Borough of Richmond upon Thames in 2005. Inside the boundary are 5 listed buildings (1 Grade I, 4 Grade II). The most significant is Kew Observatory, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
