The Pump House

The Pump House is a two-storey industrial building dating from the 19th century, constructed of red brick with dark brick dressings. It features a tall south tower, which may have served as a former accumulator. The building has hipped slate roofs, with projecting parapets and eaves that include diagonal headers. The window bays are treated with a giant arch design, while the western end has modern brickwork that lacks dark dressings. The tower and adjoining bays have roll-moulded angles in dark brick, and the top of the tower includes oculi in blind panels, a stonework band course, and eaves. There is a datestone at the base with a partly modern inscription, along with an inset modern relief sculpture. To the right, there are modern glazed lean-to extensions, and the main entrance is accessed via modern steps.

The rear elevation, which faces Gloucester Place, has mostly original detailing and features a three-bay design. The wall steps down to the east, with blind panels above a three-bay arcaded ground floor. A further three-bay arcaded and gabled elevation faces east.

Additionally, a half-length bow-trussed girder swing-bridge, which was formerly operated by power from the Pump House, still survives on the quayside to the southwest.
