Agricultural range at Tre-Ddafydd-uchaf also known as Tre-Ddafydd-fawr

Agricultural range comprising cowhouses, corn barn, stables and hammels. Central range orientated N-S, with barn to centre and cowhouse at S end extending E; hammels to N of barn extending W, forming right angled Z-plan. The range is well-constructed with rubble walls and contrasting limestone dressings; openings have segmental brick heads with dripcourse. Hipped slate roof. The S range comprises 3 cowhouses, two x 2-bay and one x 1-bay, with square high level ventilation openings to the two units to the left (E), which are windowless. The 2-bay cowhouse to the right has a central door with a window either side. In the SW angle, and forming the S end of the central range, is a 4-bay cowhouse with a central door flanked by windows. In the centre of the central range is a taller 3-bay corn barn. Tall opposite doors asymmetrically placed to the left, with 3 tall vent slits to its left and 4 to the right, with limestone architraves. North of the corn-barn are two stables (?), one 2-bay and one 4-bay, each with one door flanked by windows; the larger stable to the right having a 3rd window to the right, probably a tackroom. At the N end of the central range is a 2-bay cartshed, each bay with a shallow brick basket-arch with dripcourse; central squared limestone pier. The hammel range runs to the W; a long range with 9 open bays facing a former hammel yard to the S (all but two of the bays have been infilled or partly infilled wth rubble). Shallow basket-arches of dressed limestone, with projecting keystones and dripcourse. Central feedroom with single narrow door access to rear (N) elevation.

Roof trusses sawn and bolted collared trusses throughout.
