Tre-Ddafydd-uchaf (also known as Treddafydd-fawr)

This is a two-storey vernacular farmhouse with a T-shaped plan and minor additions. All parts have rendered masonry walls and thin slate roofs with rendered chimneys.

The original part of the house, dating from the late 16th century, forms the stem of the T. It is an asymmetrical two-window range with the main entrance facing east. The entrance has quarter-round moulded jambs with a round head set in a square frame, and a dropped and returned moulded label. To the left is an original three-light mullioned window with chamfered mullions and moulded label. The jambs, lintel and sill are hewn from single sandstone blocks, with an inscription on the right jamb reading "H W 2 6" over "1730" (or possibly 80). The moulded sandstone architraves and cornice mark the quality of this early work. Two windows occupy the first floor: a small square-headed window with quarter-round moulded jambs and small panes to the right, and a six-pane sash with vertically-proportioned panes to the left. On the west side is a modern doorway with 16th-century moulded jambs reset on the inside, now opening into a back-kitchen. Below this is a 17th-century squared-headed window with plain chamfered jambs, and above it a smaller square-headed window with moulded jambs. A blocked doorway at the south end may mark the position of the original west entrance.

The gable end stacks define the extent of the original house: the one to the right (north) has hollow-chamfered capping and dates from the 16th century; the south stack was added in the 18th century.

The head of the T comprises a 17th-century cross-wing to the east, lengthened westward in the 18th century. The cross-wing probably originally had its west wall in line with the rear wall of the earlier house, but this was removed when the wing was extended to its present size in the 18th century. The north wall has gable end chimneys and a projecting chimney in the lateral wall. A reset doorway of the late 16th century, with double roll-moulded jambs with broach-stops and a square head with moulded label, appears to the right of the lateral stack. To the left of the chimney is a 16-pane hornless sash window to the ground floor with a four-pane sash above, and above the doorway is a narrow four-pane sash. The 18th-century addition to the right has a 16-pane horned sash window to the ground floor with a narrower 12-pane horned sash over. In the east gable end of the cross-wing is a 16-pane sash to the ground floor with a four-pane sash to the first floor, not aligned.

Abutting the rear (west) side of the 16th-century house is a 19th-century single-storey back-kitchen with gable end chimney, rendered walls and grouted slate roof. A door on the north side has a window to its right. Abutting the south gable wall of the 16th-century house is a single-storey dairy with rendered walls and pitched grouted slate roof. There was formerly a horse engine to the south, used for churning. In the southeast angle of the T is a lean-to with a catslide slate roof, following the pitch from the cross-wing, with a raking dormer window.

Internally, the 16th-century house originally had one room only to the ground floor, with the principal entrance to the east and probably a secondary entrance to the west side. At the north end is a large fireplace. The interior has since been subdivided and modernised. The older cross-wing is said to contain two rough-hewn cross beams carrying stop-chamfered floor joists; above the fireplace opening is a flat chamfered beam. The later wing and the whole of the first floor have been modernised.
