Western Winding House and Shaft Head Gear (Winder and Shaft No 1)

The Western Winding House and Shaft Head Gear, also known as Winder and Shaft No. 1, was built around 1894, with an early 20th-century extension. It is constructed from yellow Ashington brick and features gauged arches over the doors and windows, topped with a Welsh slate roof. The structure is a rectangular, three-storey winding house with a single-storey extension to the west and a shaft located to the south. The side walls have three bays, while the rear has two bays, all defined by pilasters that rise to a stepped-and-cogged eaves cornice. The large round-arched windows contain metal-framed casements, and one rear window has been replaced by a later doorway leading to an external platform. The lower floors feature round-arched doorways and windows, including an arched doorway that connects the upper floor to a walkway leading to the cage. The roof is hipped, with a gabled wooden dormer for the winding ropes and a raised louvre on the ridge.

The extension has a blocked arch on the south side and a four-bay west wall that mirrors the winding house's detailing and fenestration, although some later openings have been added below the sill level; it also has a hipped roof. The shaft head gear consists of a skeletal frame, which has been partially boxed in with corrugated sheets.

The sinking of the shafts began in 1894, and the first coal was produced on February 13, 1901. A steam engine was replaced by an electric winder in 1975, and there are two compressors located in the basement.
