Former Llay Hall Colliery Washery Building

The building is of the typical and highly characteristic construction of early washeries, consisting of brick panels supported on a bolted and riveted steel frame exposed to the facade. The framed construction supported vibrating machinery and permitted flexible internal use. There are square-headed metal framed windows, some inserted during conversion. The building is of an irregular form, with rail and conveyor access, and varying numbers of storeys, built into sloping ground. The overall plan is an oblong aligned north-west to south-east. At the north-west end is a two-storey section with a gable facing the front. To the south-east is a four-storey block with two transverse gables, one larger and higher than the other. On the north-east side of this section, the building extends over a former rail line for hopper loading. A rare surviving section of covered conveyor route, with a concrete ramp and steel frame supporting a segmental roof, slopes to ground level at the northern corner of the building. Inside, the building has been divided into workshops, stores and offices.
