About the Ickenham Village Conservation Area
The Ickenham Village Conservation Area covers about 93 hectares within London Borough of Hillingdon’s area. Inside the boundary are 21 listed buildings (3 Grade I, 1 Grade II*, 17 Grade II). The most significant is Ickenham Manor, Grade I. 1 Article 4 direction over the area removes further householder rights, on top of the conservation area limits below. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
