Description
The engine house, dating from the 19th century, features a gable-ended design and is accompanied by a tapering cylindrical brick chimney stack that has a neck band and cornice, rising from a square base. The slate roof includes ventilators. The front of the building has a central round-arched entrance, which is framed by red brick voussoirs and has modern doors beneath a fanlight. In the gable, there is a circular ventilator. On either side of the entrance are service openings, with the right one altered to include an inserted window. Additionally, there is a small squared brick stack.
The south wall of the central section of the three former kitchen gardens runs along the north side of the engine house, and there is an arched entrance at this location.
Inside, the engine house retains a furnace boiler made in 1854, which has a foundry plate from 'Thomas and De Winton of Carnarvon'.
