Description

This is an agricultural range arranged around a courtyard, constructed in several phases during the 18th and 19th centuries. The southwest range incorporates a four-bay corn barn, dated 1792, with a three-bay lofted stable attached to its northwest gable and a single-story cowhouse extending to the southeast. The cowhouse returns to form further cowhouse ranges to the southeast and northeast. A lofted, twin-bay cartshed, dated 1829, abuts the northwest range, and is in turn attached to a single-story, five-bay cowhouse.

The southwest corn barn has rubble walls and a roof of small slates, notable for its unusual dressed stone ridge pieces. A pair of wide, central doors originally spanned the full height of the barn, later given segmentally arched brick heads with dripcourses. These doors are flanked by two tall ventilation slits; the one on the southwest side was widened, likely to accommodate a drive belt. The attached lofted stable is similar in construction, with access to the loft via a stone staircase in the northwest gable and a four-light window on the same elevation. A blocked doorway is present in the southwest elevation, alongside a roofless, stone-walled lean-to. The stable has a single door in the northeast elevation, with a boarded door and a four-light overlight, and a small window to the right.

The northwest range features a twin-bay granary-cartshed abutting the stable. It has rubble walls, a slate roof with stone copings, and wide cart bays with shallow, stone basket archways, each having a dripcourse. Between the bays, at loft level, is a full-height doorway that is now largely infilled with brickwork, with a small three-light window in its place. An original small, six-light granary window is visible on the left side. Above the left archway is a slate tablet inscribed "O.W." over "1829." A stone staircase provides access to the granary loft from the rear (southeast) elevation, with a boarded door. A small, four-pane granary window is centrally located on the rear elevation. Brick dove boxes are integrated into the northeast gable. A single-story, five-bay cowhouse is attached to the northeast gable of the cartshed, constructed with rubble walls and a roof of profiled asbestos sheeting. This cowhouse has a central door in each long wall, flanked by iron-framed windows. A cut doorway is present in the northeast gable wall, with brick jambs, and a window above where a loft once stood.

The southeast and northeast ranges are single-story cowhouses with rubble walls and roofs of profiled asbestos sheeting. The southeast range has wide doors at its southwest end, leading to a hammel yard. The northeast range features three former wide openings on its northeast elevation (facing away from the yard), now blocked to create narrow openings with doors and windows.

The corn barn was originally five bays, but was reduced to four bays when the right-hand bay was remodelled to incorporate adjoining buildings. Inside, it has collared trusses with pegged half-dovetail collars and two rows of square purlins. The date '1792' is painted onto the collar to the northwest of the threshing floor.
