About the West Bank Promenade Conservation Area
The West Bank Promenade Conservation Area covers about 2.1 hectares and was designated by Halton Borough Council in 1976. Inside the boundary are 3 listed buildings (2 Grade II*, 1 Grade II). The most significant is Church of St Mary, Grade II*. 2 Article 4 directions over the area remove further householder rights, on top of the conservation area limits below. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.

Article 4 directions here
These overlap the conservation area. Householder directions remove more of the rights above; change-of-use ones don’t affect extending a house.
