Llwyngoras, including Garden Walls with Gate Piers

Llwyngoras is a farmhouse dating to the 18th century, with a substantial rear wing and garden walls. It is a building of group value, demonstrating significant architectural interest. The main range has a projecting porch gable to the east front and a large projecting wing to the west, creating a rough cruciform plan. The original construction is rubble stone, initially roughcast, now with slate roofs. A rebuilt stone stack is located at the northern end. Originally, chimneys were present on all four gables, including the porch. Windows are generally sash windows, although some have been replaced with aluminium.

The east front features a projecting porch with a cambered head over the doorway, a 20th-century window above, and a lean-to to the right with a 12-pane sash window. The porch interior contains seats flanking a fine ogee-moulded oak doorcase with a 6-panel door. To the right of the porch, one 6-pane upper window remains visible, alongside an early 19th-century drawing room addition at the north end. To the left of the porch is a single window range with a 12-pane sash below and an aluminium window above. The early 19th-century north addition incorporates a full basement storey and a raised ground floor, topped with a hipped slate roof. An external door is on the east end, with two windows (one blank, one 12-pane sash) on the north front above cambered-headed cellar windows. A French window is located at the west end.

The west front displays a large gabled wing, roughcast and whitewashed, with an outshut to the south, featuring a round floor door and window, and two 12-pane sashes above. A long 24-pane stair light is set into the north side wall. To the left of the projecting wing is a single-window range of the main house, followed by a French window from the early 19th-century drawing room.

The front garden is enclosed by curved rubble walls with ball-finial corniced piers marking the gateway.

Internally, the main ground floor room, possibly originally subdivided by a screen, has five massive chamfered spine beams with run-out stops and scratch-moulded joists. A large inglenook fireplace at the north end incorporates a beam dated 1578, while a fireplace at the south end is blocked. A staircase rises from the south side of the hall, turning sharply. It may have 18th-century square newels and a moulded rail. The rear wing features heavy ceiling beams resting on a large, reused beam along the wall between the wing and the outshut. A fielded panelled door is positioned near the stairs. The early 19th-century drawing room has a Regency-style panelled door with overlight, a plaster cornice incorporating acanthus, vine scroll, and reeded borders, and a black marbled slate fireplace. The cellar beneath has storage recesses within the walls. The first floor has a spine passage and some 6-panel doors. Dog-leg stairs lead to an attic containing heavy roof timbers, including two trusses with peg-holes for collars in the rear wing and a triple-purlin main roof with curved collars. The top of a lateral chimney shaft, apparently never used, is visible to the left of the porch roof.
