Dryslwyn-fawr Barn Range

Dryslwyn-fawr Barn Range is a double barn built with opposed barn doors leading to two threshing floors. It features a granary loft at the south end above two cartsheds, and a lower-roofed cattle-shed extension, which may have originally served as a stable, also at the south. The structure is constructed of rubble masonry with limestone quoins and dressings around the openings. It has slate roofs with tile ridges and slit ventilators in the walls. The barn and cartshed doors have segmental heads, while the hatches at the front and rear of the granary feature flat arches with large impost stones. The cattle shed has two windows at the front, two blocked windows at the rear, and a loft hatch in the gable, all with similar arches. There is a small brick extension at the rear under a catslide roof.

The barn section consists of eight bays and has a flagstone floor. It contains two threshing areas, with a small area of inserted upper floor between them that includes a surviving length of lay shaft with three belt pulleys. At the south end of the barn section, stairs lead up to the grain loft, which is plastered. The four-bay livestock shed at the south has a drained paving-brick floor, a manger on the east side, and a partially surviving hayloft.
