Calder and Hebble Navigation Old Lock House Fronting Brighouse Lower Lock

The Old Lock House, located at Brighouse Lower Lock along the Calder and Hebble Navigation, is a lock-keeper's house built in the early 19th century. It is constructed from hammer-dressed stone and features a stone slate roof. The two-storey house has two bays and includes a single-storey octagonal office that projects forward between the bays, creating a stubby 'T' plan. The design is symmetrical, with a doorway that has monolithic jambs and is flanked by four-pane sash windows beneath a cambered arched lintel, with stones treated as bricks and a projecting sill. The hipped roof has a tri-partite hip, and the return walls are blind. The house has similar windows on the first floor, with one in each bay and additional windows in the return walls. A large brick chimney stack is positioned at the junction of the office and the house. To the left of the front, a garden wall indicates the flood mark of 14 feet from an event that occurred on November 16, 1866.
