Barn to west of Pentrebane Farmhouse

The barn located to the west of Pentrebane Farmhouse is a large structure built in the early 18th century. It features rubblestone walls and a roof that has modern external cladding. Each long side of the barn has two waggon entries, which are designed as short gabled wings. There are tall ventilators positioned near the ground and smaller ones near the eaves, with two sets of ventilators between each waggon entry and the outer corners of the barn, as well as three sets in the central section of each long wall.

The waggon entry wings have stone walls with semi-elliptical brick arches, supported by stone pilasters and caps at the yard entrances. Above these arches are blind circular lunettes made of brick, with stone voussoirs at each 90-degree angle. These features strongly suggest that the barn was constructed in the early 18th century. Additionally, there are tall segmental-headed brick doorways in the long walls at the points where the waggon entries meet the barn.

On the east side of the barn, one-storey outbuildings have been constructed at right angles. At the southern end, next to the southern waggon entry, there is an outshut with semi-circular headed brick arches. The southern wall of this outshut connects with another similar outshut. A further outshut is located against the middle section of the western long elevation of the barn.

The south gable of the barn features three tiers of slit vents, with lean-to sheds added on either side. During the recent survey, the southern end of the barn was filled with hay, making it difficult to count the number of bays, but it is estimated to have thirteen or fourteen bays. The five bays north of the northern entry were empty and displayed mechanically sawn king-post trusses, along with the remnants of a tallet over a stable. The roof appears to have been placed on specially heightened walls, indicating a modification made in the mid-19th century. There is a stone-paved threshing floor in the opposing opening.
