Plas Power Colliery was established in 1875 by the Old Broughton Coal Company (later the Broughton and Plas Power Coal Company). Its directors in 1881 included three of the most important industrialists in Wales, Henry Robertson, W.H.Darby and C.E.Darby, who were also the owners of Brymbo Steelworks. The colliery was one of the largest and most modern in North Wales at the turn of the century, and at its peak employed 1,100 men, The steam coal produced was used in railways and shipping, notably supplying companies such as Cunard, P&O, the Great Western Railway, and the Great Indian Peninsular Railway. The colliery closed in 1938. The workshops range appears to date from the original establishment of the colliery.


The workshops form an exceptionally long and thin single-storey building, roughly 55m by 10m. It is constructed of roughly coursed sandstone with a corrugated gabled roof. Tall windows on the long elevations are irregularly spaced, but represent roughly 22 bays. Most have round-headed arches, but some have straight stone lintels. There are three square-headed openings to the SE gable. Most windows are blocked or have replacement glazing. Two red-brick chimneys are positioned at the apex of the roof in the E half of the block.


The building is divided into separate workshops along its length with stone walls and later partitions. There is a king-post timber roof.
