Barn at Pen y bryn

The barn at Pen y Bryn is a small structure built from local rubble stone, with the smaller stones suggesting they may have come from field clearance or quarry waste. The rear and upper gable end are made of this stone, while the plinth is also stone. The front wall shows traces of timber-framing but has been largely opened up to create three wide double doorways. The lower gable end is clad in corrugated iron. The roof is covered with artificial slate.

On the rear elevation, there is a small lean-to extension on the right side, which is the downhill side. This extension has three doorways in its long wall, with one doorway below that provides access to a lower storage bay. All the openings, including those in the lean-to, feature cambered brick heads. The plank doors are recent but designed in a traditional style. There is also a small loading door to the loft in the upper gable.

Inside, the barn has three bays, with the upper bay now partitioned off. A cruck truss is located between the central and upper bays, featuring a tie beam and a king-post that supports a slightly cambered collar. There are traces of a partition in this area, including two posts below the tie-beam and a sill. Between the central and lower bays, there is a queen-post and collar truss, with remnants of a partition that includes a central post and a sill beam resting on a stone plinth.

Elements of the framing on the front wall are still visible, including a jowled wall-post associated with the central truss, although the tie-beam rests on the stone wall at the rear. The barn features two tiers of purlins and a ridge beam. The lower gable end is also timber-framed and has a queen-strut truss, with lapped vertical boarding as cladding. The lower bay is stepped down to follow the slope of the ground and can only be accessed via an external rear doorway. The upper bay is partitioned and has been storeyed, although it was likely originally lofted, and features modern glazing with timber mullions on the front wall.
