Brondyffryn Farm, including associated walls fronting the lane

L-shaped, 2-storey farmhouse and barn group. Of whitened rubble with whitened brick to the inner (courtyard) elevation of the farmhouse section; slate roof, hipped to the corner, plain brick chimneys. The 3-bay courtyard side of the farmhouse has a central entrance with boarded door and plain overlight. This is flanked by 12-pane unhorned sashes on 2 floors, all with projecting stone sills and segmental heads. The entrance and L window occupy reduced depressed-arched cart/coach bays. The upper windows break the eaves and are contained within gabled dormers with pierced bargeboards. The road-facing elevation of the farmhouse has a boarded early C19 entrance with 3-pane overlight and a small 4-pane window above; 12-pane sliding sashes to the L on both floors. The L return has a similar sliding sash with a 6-pane first-floor sash window.

Adjoining at right-angles to the R is an integrated barn range, the first section of which is a continuation of the house. This has a cambered, boarded entrance with 6-pane windows to the R. Beyond this is the barn with large cambered entrance having boarded doors; vent slit to L. To the R of the barn entrance is an outshut with 2 cambered, boarded entrances having pegged frames; cambered window to the R with plain modern windows.

In front of the farmhouse, enclosing a triangular garden, and continuing to the L to run parallel with the lane, is a rubble wall approximately 1.5-1.8m high. This bounds the lane opposite the walls of Tros-y-Parc and Llys-y-Coed, until it terminates at the junction with a farm building at right-angles with the road.

The interior was not inspected at the time of survey.
