About the Hammersmith Broadway Conservation Area
The Hammersmith Broadway Conservation Area covers about 7.5 hectares within London Borough of Hammersmith & Fulham’s area. Inside the boundary are 11 listed buildings (1 Grade II*, 10 Grade II). The most significant is Church of St Paul, Hammersmith, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
