About the St Ippolyts Conservation Area
The St Ippolyts Conservation Area covers about 4.5 hectares and was designated by North Hertfordshire District Council in 1990. Inside the boundary are 7 listed buildings (1 Grade I, 6 Grade II). The most significant is Church of St Ippolyts (church of England), Grade I. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
