Fan and Compressor House

The main building is a single-storey, rectangular, red-brick construction with dressed stone plinth; three bays to the side elevation and three bays to the gable end. There are extensions to the south-east, south-west and north-east and a low structure to the north-west. In the south gable are two identical arched doorways with wooden double doors. A third, taller, central arch is blocked. The slate roof is pitched with tiled ridge and a large square chimney base is in the south-west pitch. The north-east elevation has two semi-circular brick arched windows. The east window has a metal duct protruding from it. A brick extension to its western end has a corrugated iron cat slide roof. The south-west elevation has two windows, one with semi-circular brick arch and the other with a segmental brick arch. There is a brick extension at its west end which has two large iron ducts leading from it. The ground to the north-west is partly built up around a long, low, brick structure with dressed stone base.

In the main building, two compressors remain together with the base of the third. Some areas of floor still have their original tiles. The roof trusses are iron. The telephonist's room in the north-west extension has the remains of the communication system. The fan housing itself was not accessible (Autumn 1993).
