About the Letchworth Conservation Area
The Letchworth Conservation Area covers about 291 hectares and was designated by North Hertfordshire District Council in 1974. Inside the boundary are 78 listed buildings (8 Grade II*, 70 Grade II). The most significant is 102, Wilbury Road, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
