Barn Range at Beiliau Farm including forecourt walls

The Barn Range at Beiliau Farm, which includes forecourt walls, is a building constructed of rubble with a corrugated asbestos roof. The east elevation features high doors on the right, a pedestrian boarded door in the center, and two loops between them. There is a small loop on the first floor left of center and a similar loop on the ground floor near the left end. To the left, there is a lower single-storey short range with a window. The rear (west) elevation of the barn has two high doorways that correspond to the doors on the east side, with corrugated iron sheeted doors. There are paired loops between the doors and another loop to the left of the left-hand doors, with a single loop at the right end. Beyond this is a straight joint indicating a later 19th-century three-bay stable, though this joint is not visible on the east side. The stable has three brick camber-headed doors on the ground floor with boarded doors and a pitching door above. To the right, there is a single-storey range with a wide opening on the left and a door on the right.

On the east side of the barn, there is a large walled enclosure that was once used as a garden but may have originally served as a rickyard. The walls connect to the barn to the left of the high door and extend eastward to follow the north-south line of the driveway into the yard. To the south, the walls extend beyond the barn range to follow the line of the by-road before returning to meet the southwest corner of the range.

Inside the barn, there is a nine-bay structure supported by king-post trusses, diagonal struts, and overlapping purlins. The threshing floor is located between the northern pair of doors.
