Description

Waterside Mill is a corn mill that was later converted into a power station and is now a semi-detached house. It dates back to the 18th century and was transformed into a power station by the Southern Tannery Company in 1929, remaining in operation until 1973. The building is constructed of English and Flemish bond brick and features a tiled roof with a half-hip on the right side.

It is three stories tall with three windows across the front. The ground floor has two three-light segmental-headed casements and a 20th-century door leading to the first-floor entrance, which is accessed by steps. To the right, there is a four-light segmental-headed casement. The second floor has two three-light casements and one two-light casement. The building also has a dentilled eaves cornice and a hipped dormer with a three-light casement in the roof.

On the right side, there is a blocked door and a planked door at ground level, a three-light casement on the first floor, a two-light casement on the second floor, and an attic window. The rear features a 20th-century door and four-light casements on the first floor, along with four two-light casements and one three-light casement on the second floor. The interior has not been inspected.
