Former Plas Power Colliery Power House

The power house is a tall building of red brick with a hipped corrugated roof, three bays by three. The windows are round-headed with brick arches and stone sills. There are three each to the main floor on the W and E sides, and an additional doorway to a semi-basement level on the E. The N elevation has two arched windows and a central arched doorway, with a large circular opening above to carry power cables. Two windows on the S elevation have been replaced with large double doors for vehicular access, but another blocked circular cable window can be seen between them. The building has a deeply corbelled eaves cornice on all sides, and a pronounced corbelled string course between eaves and window heads. Many metal brackets survive around the exterior of the building; these held insulators and cables.
