About the Walkern Conservation Area
The Walkern Conservation Area covers about 49 hectares and was designated by East Hertfordshire District Council in 1981. Inside the boundary are 38 listed buildings (1 Grade I, 6 Grade II*, 31 Grade II). The most significant is Parish Church of St Mary the Virgin (church of England), Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
