About the Hertingfordbury Conservation Area
The Hertingfordbury Conservation Area covers about 24 hectares and was designated by East Hertfordshire District Council in 1968. Inside the boundary are 27 listed buildings (2 Grade II*, 25 Grade II). The most significant is Amores Including Outbuildings, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
