Former Diffwys Railway Station (now public toilets)

The former Diffwys Railway Station, now serving as public toilets, is a small, single-storey building with a symmetrical front and outer gabled wings. It is constructed of snecked rubble with dressed quoins and a moulded string course above the central openings, featuring yellow brick surrounds. The slate roof displays a fish-scale pattern, complemented by clay ridge tiles and red and yellow patterned brick stacks. The bargeboards are adorned with ironwork cusping.

Above the recessed boarded doorways, which have modern doors, are slate gable plaques featuring the Prince of Wales feathers, carved by Robert Roberts, a poet and carver. The central section includes a modern arched entrance for disabled access, flanked by original sash windows. There are arched doorways at the blocked inner angles, matched by an oculus above the ticket opening, which has a slate cill. Modern Victorian-style bracketed lamps are positioned above the doors. The forecourt is paved with modern brick and features iron bollards. At the rear, there is a single opening with a toothed surround and double boarded doors, while the west gable end has a Gothic-headed sash window.
