About the St. Peter's Square Conservation Area
The St. Peter's Square Conservation Area covers about 11 hectares within London Borough of Hammersmith & Fulham’s area. Inside the boundary are 22 listed buildings (1 Grade II*, 21 Grade II). The most significant is Church of St Peter, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
