About the Watton at Stone Conservation Area
The Watton at Stone Conservation Area covers about 32 hectares and was designated by East Hertfordshire District Council in 1975. Inside the boundary are 26 listed buildings (2 Grade II*, 24 Grade II). The most significant is Church of St Andrew and St Mary, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
