Engine house and chimney about 30 metres to north west

The engine house at Cotehele Consols mine, now a house, along with its chimney, dates from the late 19th century and has undergone some 20th-century alterations. It is constructed of slatestone rubble with brick dressings and features a slate roof with gable ends.

The engine house has a rectangular plan and includes a gable end bob wall on the south side, where the bob opening has been modified into a large window. There is an adjacent rectangular building on the right side, which may have originally served as a boiler house. The chimney, located about 30 metres to the northwest, has a circular plan.

The exterior of the engine house is two storeys high, with round-arched windows on each side that have had 20th-century windows inserted, featuring splayed glazing bars. A 20th-century door is located on the right side. The front gable end contains the bob opening, now with a large 20th-century window inserted at the upper level. In front of the engine house is a platform for machinery. The adjacent building is also two storeys but is roofless and has door and window openings. The chimney is made of rubble, is circular and tapered, and has a brick top with a cornice.

The interior has not been inspected.

Historically, in 1883, Cotehele Consols was worked alongside Okeltor Mine, processing iron pyrites from Cotehele Consols for arsenic.
