Former Llanbradach Colliery fan house

The former Llanbradach Colliery fan house is a long, roofless building constructed of snecked rock-faced sandstone. The central engine hall once housed the electric motors that powered the fans, with fan chambers and evasees located at either end. The west side features seven bays, with the southernmost bay set back and mostly demolished, but it retains round-headed windows arranged in two groups of three. On the south side, there is a concrete projection of the No 2 fan casing, topped by a castellated evasee. The north side includes another evasee, which dates from the conversion to a Scirocco fan, as well as external stairs leading to a round-headed doorway. The east side has a brick arch that connects to the fan drift.

Although not inspected in November 1998, it is reported that the building retains internal divisions for the fan chambers, complete with openings for drives. Visible in the engine hall are the engine beds for the fan engines, a glazed tile dado, decorative plasterwork on the walls, and a spark-retardant floor surface.
