Hetty Engine House

A monumental gabled engine house of banded 3-storey height, of snecked rock-faced stone and slate roof. The windows are boarded up but retain iron frames behind, some with addition wood-framed glazing bars. The engine is housed in the upper storey. In the N gable end is a large round-headed opening now blocked. The diagonal feet of the headframe are crudely inserted to the R and L, while the winding ropes enter through the roof. On the L-hand side are 4 round-headed keyed windows with sills and a central doorway reached by external steel walkway over the former boiler house walls, above which is a tablet with the date inscribed. The steam pipe is retained just below the upper plinth on the L side. In the R-hand side wall is a doorway at the L end (formerly a window) and 4 windows, the central of which is lower and was formerly a doorway. In the S gable end, overlooking the road, are 2 round-headed windows in the upper storey and 2 small openings boarded up at the ends just below the band.

At the base is a round-headed through passage at the S end. On the W side to its L is a blocked inserted window with brick surround. On the E side is the former boiler house wall, of rubble stone.

The interior retains a double-cylinder engine by Barker and Cope, modified by Worsley Mesnes, with winding drums. Traces of scribed plaster are retained to the walls. The roof is 5 bays with the trusses hidden behind asbestos panels. Traces of a ribbed ceiling can be seen behind the asbestos.
