Old Post Office Farm

Old Post Office Farm is a 17th-century house located on Back Lane in Longdendale. It features squared coursed rubble construction, a graduated stone slate roof, and a brick chimney stack. The building has a 2-bay baffle-entry plan, is two storeys high, and includes a two-storey porch. It has one room in depth and a slightly later wing added to the rear. The facade is symmetrical and showcases a 5-light window with three mullions removed, along with three 3-light windows, one of which also has a mullion removed. All windows have double-chamfered stone mullions.

The central porch has an off-centre chamfered door surround, a round-headed light on the first floor, an owl hole, dove holes, and a coped gable with kneelers and ball finials. A central ridge chimney stack is present, and the rear of the building has two windows with a mullion removed and a round-headed attic gable light. Inside, there is a wattle and daub timber-framed partition spanning two floors. The door lintel is inscribed with "NWM 1694," indicating the names Nicholas and Martha Wagstaffe. The left-hand bay of the building is part of the former No. 50 Market Street.
