Engine House, Boiler House and Chimney at Clevedon Pumping Station

The Engine House, Boiler House, and Chimney at Clevedon Pumping Station were built in 1901. Designed by engineer James Mansergh and architect Henry Dare Bryan for the Clevedon Waterworks Company, they are constructed of squared and coursed Pennant rubble stone with ashlar dressings and a plain clay tile roof.

The building comprises parallel engine and boiler houses, with a chimney stack connected to the north side of the boiler house via an inspection chamber. The design incorporates elements of the Domestic Revival style alongside Free Renaissance influences.

The principal south elevation of the engine house features three bays, with the central bay projecting forward and topped by a segmental-pedimented gable. A four-centred arched doorway, flanked by foliate carvings to the spandrels and scroll carvings to the curved keystone, leads to the interior. Above the doorway is a four-light mullion window, and the outer bays contain six-light mullion and transom windows. Battered diagonal buttresses with consoles mark the corners. Decorative stone finials adorn the gable verges of both the engine house and boiler house. The engine house’s gable features a keyed oculus between ashlar bands, and a twelve-light stone mullion and transom window sits to each side. A timber lantern, surmounted by an octagonal domed cupola with louvered sides and a weather vane, rises from the roof ridge.

The boiler house is lower and wider than the engine house. Its west end has two round-headed carriageways with a four-light mullion window above. The rear elevation incorporates four three-light mullion windows, while the east elevation, which extends eastward, includes two nine-light and one four-light mullion and transom windows. A single doorway with an ashlar surround and a three-light mullion window above are present on the south elevation of the boiler house.

Inside the engine house, a painted brick arch appears over the doorway, supported by stone pilasters with corbelled capitals. Originally containing an engine, the space now houses electric pumps and modern control equipment. The roof structure utilizes arch-braced Queen-post, double-collar, and tie-beam timber trusses with struts and cusped heads to the upper collar. The boilers have been removed from the boiler house, which also now accommodates modern control equipment, and a partition wall now divides the east end.

The chimney stack rises from a square base as an octagonal shaft, incorporating moulded ashlar panels, corner consoles, corner water spouts, and a decorative, octagonal ashlar top section.
