About the Walham Green Conservation Area
The Walham Green Conservation Area covers about 12 hectares within London Borough of Hammersmith & Fulham’s area. Inside the boundary are 7 listed buildings (1 Grade II*, 6 Grade II). The most significant is FULHAM TOWN HALL (original building and 1904-5 extension), Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
