Bersham Colliery Winding Engine House

Bersham Colliery Winding Engine House is a two-storey structure built of red brick, featuring a barrel vaulted concrete roof supported by steel girders. The building measures five bays long and three bays wide, with windows that have flat concrete lintels and sills, and small pane metal frames. The long elevations are marked by panels separated by pilasters topped with corbelled heads. The first floor, which houses the winding engine, has large windows, while the ground floor has only one window. Access to the first floor is provided by a steel staircase leading to a door on the western side. The gable ends of the building have stepped parapets, with the gable facing the headframe featuring a raised central section for the winding cable line and a pair of buttresses at the front. There are also two covered openings that previously allowed the cable to pass through. A contemporary two-storey wing is attached to part of the eastern long elevation.

The Metropolitan Vickers winding engine, installed in 1962 when the winding was converted to electricity, is located on the first floor, and the large drum may be original. Adjacent to the engine is an engine man's cabin made of steel and glass. The interior of the building is partially divided into offices and store rooms on both floors.
