Surrey Street Pumping Station

Surrey Street Pumping Station was built in four phases, beginning in 1851, and later extended in 1867, 1876-7, and 1912. It is popularly believed that the original 1851 engine house was constructed from materials re-used from the converted West Croydon atmospheric railway station's engine house of 1845.

The 1851 building is in a Neo-Tudor style. It is built of brown brick with stone quoins and has a slate roof. A five-light stone oriel window is on the west gable wall, with date plaques above. The north front has two three-light windows on each floor, with four-centred heads and labels. A single dormer is also present, with a gable over the left-hand windows.

Adjacent to this is the engine house of 1867, designed by C. Baldwin Latham, in a castellated Gothic style. Constructed of stock brick with polychrome brown brick and stone dressings, it features an octagonal castellated tower at the north end with pseudo-machicolations, lancet windows, and a concrete door surround dated 1954. The north front has two three-light casement windows with leaded lights, pointed heads, polychrome voussoirs, and zigzag decoration using three colours of brick (yellow, red and black). The castellated parapet also incorporates pseudo-machicolations and buttresses.

A further addition of 1877 by Thomas Walker, built of stock brick with stone dressings, is a single-storey building with five windows. Recessed window bays lead to an entrance on the north side, which is set under a gable. The south face has a gable with an oculus and two lancets. The final extension, of 1912, is built in stock brick and red brick with a slate roof.
