About the Berkhamsted Conservation Area
The Berkhamsted Conservation Area covers about 116 hectares and was designated by Dacorum Borough Council in 1969. Inside the boundary are 61 listed buildings (1 Grade I, 3 Grade II*, 57 Grade II). The most significant is Berkhampstead School Old Building, Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
