Barn at Llandyn Hall

The barn at Llandyn Hall is a Grade II listed structure primarily built of rubble, with some lightly dressed Ruabon stone at the lower end. It features an undulating slate roof that dog-legs to the right over a two-storey lean-to. This barn exemplifies a type that was common in the area for two main reasons: it has only one door at one end of the threshing floor, which may indicate that the cross range replaced a second door, and it is built into the slope, with animal accommodation located beneath the barn at the lower end.

To the east, opposite the door, is a cross range, with various later additions to the south. The west side includes a high cart entry with a swept roof at the center; however, the doors have been removed, and the jambs have been rebuilt. There are slit ventilators to the left and a shallow close-studded band, likely added later, over a low cartshed. One beam is inscribed with "W X E." The loft is accessed from the upper gable end through a similar 'black and white' door, and this area is separated from the main barn by a stone wall and a closed truss.

There are 19th-century stables in a dog-leg formation to the right, and a change in masonry is evident to the right of the upper door. At the lower end, there is a rubble two-storey range with a flatter pitched corrugated iron roof, along with a lean-to on the gable end. The cross range at the rear also has a corrugated iron roof and a red brick gable end, suggesting it may have been an afterthought. The main roof dog-legs at the rear as well.

Internally, the pegged roof trusses have been altered and reinforced over time. They include tie beams, queen struts, lapped purlins, and ridge beams, with numerous additional purlins and struts added. The truss to the left of the threshing floor intersects with the base of the end truss of the cross range, as do the purlins.
