Valve House

The Valve House is a single-storey building constructed of brick, faced with snecked, rock-faced Cefn stone, featuring rusticated quoins and dressings. It has a slate roof with overhanging eaves. The east and west walls contain small round-headed openings, although the glazing bars are missing, and these openings have prominent keystones. The south wall has a larger round-headed window. On the north side, there is a round-headed doorway with a planked door. Above the openings, there is a deep cornice supported by a corbel table, and the side walls are made of dressed stone, while the gables are faced in blue brick. Inside, there is a brick floor that includes a valve control lever, an exposed valve rod, and fixing bolts for another valve rod.
