Engine House at Sj 866 568

The engine house, serving a now-disused coal mine, dates from the early to mid-19th century and has some 20th-century alterations. It is constructed from rough chisel-dressed and squared, coursed rubble, with a corrugated roof that was still partially intact during a survey in November 1984. The building has an 'L'-shaped plan, which includes the engine house and an attached lower wing that may have been used for stables or workshops, with the foundations of a winding house beyond.

The engine house is two stories high and features a three-window front, with a chamfered eaves course. Both levels have round-arch cast-iron casements. There is an arched entry on the southeast side, next to a single-storey workshop or stable. This area also has chamfered eaves bands and small round-arch casements flanking two arched entries that are now blocked. The remains of the winding house are located at the southeast end. The single-storey wing and winding house face directly towards the mine shaft, which is approximately 25 meters to the northeast. The earlier coal mining operations at Biddulph were located on the hillside, while later mines were developed in the valley.
