Barns at Llanrhaeadr Hall, including Garden Walls adjoining to the N and NE

The complex comprises a large corn barn with a lower barn attached to the north, and adjoining red/brown brick garden walls. The barns are constructed of limestone rubble with hipped slate roofs. The principal barn has an off-centre entrance on its eastern side, facing the yard, featuring a cambered head and modern boarded doors. Flanking this are two pairs of ventilation slits at the base and under the eaves. The western side mirrors this arrangement, with a similar entrance having a part-glazed modern door, and a segmentally-arched opening above with a modern two-pane window; again, with ventilation slits below. The lower barn adjoins flush and has a full-height entrance to the left (north) side with a cambered timber lintel. The rear of the lower barn has a boarded window on the right, which was formerly an entrance, and two vents on the left.

The garden walls enclose the former kitchen garden in a roughly rectangular area measuring approximately 35 by 45 metres, and they extend to the north and northeast. They reach a maximum height of 3.5 metres and are constructed of red/brown brick in English Garden Wall bond. The copings are mostly slate, although some are stone with a triangular profile; there is plain external buttressing spaced at 5-metre intervals. The southern stretch, which closes the yard to the north, has a long, modern lean-to along its western section, with a large entrance with modern boarded doors. Approximately 15 metres east of this, a 10-metre section of rubble wall extends at right angles to the south, forming the eastern boundary of the yard. East of this, the wall has a small rubble outbuilding with a boarded door and a blocked window opening to its southern side. Adjoining this to the right is a modern corrugated-roofed lean-to with a primary cambered opening, currently bricked up. At the corner, adjoining the eastern stretch of the wall, is a modern breeze-block open lean-to with a further open entrance, incorporating a boarded door. The wall's western stretch steps down in 5-metre sections and retains its original stone copings.

The interior of the barn has been modernised and sub-divided. While the trusses were not visible during inspection, they are apparently original.
