Vivian engine house

A two-storey gabled structure, formerly with a slate roof. It is constructed partially in dressed sandstone, partially in snecked rubble, and partially in grey bricks (made at the copperworks). The oldest part of the building appears to be in the south corner, where there is much dressed stone. The building has been widened to the north and raised in height using grey brick; the raised band being given red brick oculi and eaves cornice. The west gable has a large doorway, over which is an ornate carved stone tablet with scrolls and flowers, reading 'Commenced August 1860; completed February 1862; V & S'. The north side has a chamfered corner and four segmentally arched windows to the main floor, with wooden frames. The east end has a tall opening for the former rope drive from the engine, and an oculus high in the gable. The south side has openings irregularly placed on three levels.

There is a main floor, open to the metal roof trusses, and a service basement below. The upper floor has a cill for a travelling crane.
