Description

This substantial barn range, known as Pen Pye, features a combination of timber framing and rubble stone. The central long walls are framed in oak, while the roof is covered with corrugated metal and stone tiles. The northwest front of the barn has central doorways leading to the threshing floor, which includes one boarded door and half doors. On the left side, the timber framing is exposed, and on the right, the walls are covered with horizontal boarding up to about 2 meters, with rare-surviving oak stave and lattice panels above.

Attached to the left side of the timber-framed barn is an extension, which includes a second threshing floor with boarded double doors. The stone wall on the left features slit ventilators at two levels. On the right side, there is a lofted cowhouse, with the ground floor having two doorways with flat heads and thin timber lintels—one with boarded half doors and the other blocked. The southwest gable of the cowhouse has a square boarded door leading to the upper pitching loft and a small single-light opening on the ground floor.

Inside, the barn has a seven-bay structure. The former timber-framed gable from a 16th-century barn is still visible on the southeast side. The interior features five tie beam trusses with raking queen struts, and one tie beam truss with queen posts that support a collar. There are two tiers of trenched purlins, and the threshing floors have low transverse stone walls on one side. The timber-framed walls include jowelled posts with brackets connecting both to the tie beams and to the wall plate, with box framing arranged in two tiers and angle braces at sill level.
