Langton Dock Pumphouse to East of Dock

Langton Dock Pumphouse, located to the east of the dock, was built in 1879. It is constructed of common brick, featuring red and blue brick and stone dressings, and has a hipped slate roof. The building stands three storeys tall, with a one-storey engine house at the rear. The second floor has a sill band and a brick cornice. The west facade consists of three bays, with a central entrance that has a segmental arch and a segmental-pointed fan above it. To the left of the entrance are two lancet windows, with a blind roundel above. The second floor features a central gabled window with a diapered pointed tympanum.

To the right, there is a projecting round tower with a rock-faced stone base and a diapered top, which has a machicolated cornice and an octagonal timber upper stage with louvred openings and a pyramidal cap. The five-bay returns have projecting ground floors with lean-to roofs and central gabled entrances; the south entrance has two arches next to the tower. The first floor has round windows, while the second floor has a central blind window flanked by other windows, and a central lateral stack that is truncated to the south. The rear engine house has four bays on both the north and south sides, with tall windows that have segmental-headed upper sections and a central gabled pointed entrance on the south side that bears a date. On the north side, there is a truncated chimney with a weathered rock-faced stone base and an upper part made of brick with set-back buttresses. The west side shows signs of a demolished section.
