The Cottage Attached At Right Angles To North West Corner Of Old Harden Grange

The cottage is attached at right angles to the north-west corner of Old Harden Grange. It is likely a house, possibly a former chapel or store-room and estate workers' rest room, dating from the 17th century with extensions into the 18th century. The building was initialed and dated "F & M" (Benjamin and Martha Ferrand), B : M 1680, and later extended in the early 18th century.

The house is constructed of hammer-dressed stone with a stone slate roof. It is two storeys high. The earliest part of the building has an arched entrance, now blocked, with voussoirs, a dated keystone, and a cyma-moulded hood mould. Above this entrance is a two-light chamfered mullioned window. To the left is a window with an architrave and cornice, featuring a decorative stop carved with a chalice and paten. Two cells to the right of the archway have double-chamfered mullioned windows, with dripmould over the ground-floor windows. A doorway with monolithic jambs and a cyma-moulded surround (possibly inserted in the early 18th century) is located to the left of a three-light window, with a five-light window above. Further along, a six-light window with king mullions is paired with a three-light window, and a doorway with a cyma-moulded surround is complemented by a two-light window above. A block added to the left breaks forward, featuring rusticated quoins, four bays under separate gables. All windows have architraves with false keystones. A matching ground-floor doorway is set in the third bay, once approached by a short flight of steps which are now gone, and is blocked. Oval windows set into the gables have raised square surrounds, with coped gables featuring ball finials to the apex and projecting rainwater spouts in the valleys. A stack to the left gable has blind arcading. An additional ridge stack is present on the 18th-century range. The original 17th-century section (the chapel) has two ridge stacks, and an unusual square bellcote to the right gable with three arched belfry openings on each face and a pyramidal roof with finial. Only the right gable has a coped gable with kneelers.

The rear of the building features a pointed-arched doorway with a raised surround and spandrels at first-floor level, approached by a flight of ten stone steps, possibly leading to the former chapel. To the right of this doorway is another entrance at ground-floor level with monolithic jambs; a blocking of a larger doorway with a wooden lintel is opposite the archway on the front.

The interior is largely gutted, but a doorway in the central passage with a cyma-moulded surround survives, leading into the 18th-century section. Below this is a cellar with two vaulted ranges and a connecting doorway with a basket-arched lintel engraved "RF 1704" (Robert Ferrand). This is likely the date of the building above. A stone table top remains, inscribed with: "THIS TABLE WAS AT HARDEN HALL when the Troops under GENERAL FAIRFAX were encamped on Harden Moor 1642".
