Barn with attached cow house at Penbedw Uchaf

This is a south-facing rubble-stone barn with a slate roof, which has been extended on the right side where the roof is hipped, and features a raised verge on the left end. Attached to the right end is an open-fronted cow shed that stands at right angles to the barn. The barn includes a central segmental-headed wagon bay doorway with a split boarded door, flanked by two tiers of partly blocked ventilation strips. To the left, there is a boarded door beneath a wooden lintel and relieving arch, and further left is a window that has been inserted into a partly blocked original window, with the dressed-stone surround partially retained. Above this is an infilled granary window that still has the sill of its original dressed surround. The right side extension from the 19th century features a lintelled doorway.

On the left gable end, there are external stone steps in two opposing flights, with the southern side being original and partly renewed in concrete. The added northern steps include a kennel hole. The granary doorway has freestone dressings and a Tudor head under a relieving arch. The rear of the barn features a boarded winnowing door beneath a wooden lintel and relieving arch, flanked by partly blocked ventilation strips. The 19th-century extension has lintelled openings for both the ground floor and loft, as well as a wide doorway in the end wall.

The cow shed, which is at right angles to the barn, is constructed of rubble stone and has a corrugated asbestos-cement roof. It is set apart from the barn by a former passage at the northern end, which is now blocked, although a corresponding rubble-stone wall remains and forms the northern side of a former stock yard. The cow house consists of seven bays with monolithic full-height columns that open to the former stock yard. Originally open, all but one of the bays have been infilled with later brick.

Inside the barn, there is a four-bay queen post roof that has been partly renewed. The right gable end of the barn, which is now concealed by the later extension, features three tiers of ventilation strips.
