Description
The former Llanbradach Colliery winding engine house is a tall gabled structure built into the hillside, facing the former shaft to the east. It is constructed of coursed rock-faced sandstone and features a replaced tile roof behind coped gables. The east gable end, which faces the former shaft, has a tall blocked opening for the winding cables, set under a keyed segmental arch and flanked by buttresses. There are inserted windows on the left and right sides of this opening.
On the south wall, there is an added lean-to on the right, and to the left of this lean-to are three segmental-headed windows in the upper storey, with original iron-frame glazing in the centre and right windows. The ground-floor openings have been altered by the insertion of doorways, although an original doorway at the left end has replaced double doors. The north wall has four windows similar to those on the south, with some openings blocked. The west gable end features a Diocletian window that has been partially cut through to create a doorway from road level to the upper storey, with an added projection beneath it.
Inside, the building has been subdivided into workshops and offices.
