Plas-yn-dinas Public House

Plas-yn-dinas Public House is a 1½ storey building featuring a two-bay main range and a crosswing. The front, which faces the car park, is characterized by timber framing painted black and white, with square panels and mostly brick nogging. It has a slate roof with overhanging eaves, tile ridges, and finials. A chimney stack that was located opposite the former entrance has been removed. The cross range extends forward on the left side and has small pane casement windows. There are two gabled dormers with casement windows on the right side of the main range. A large recent flat-roofed extension has been added to the front, and there is another extension to the right, which appears to have been stables and is now being converted into kitchens.

The rear of the building, facing north-west, is made of white-painted brick in 18th century brickwork that is irregularly bonded, featuring raised black painted two-course bands. The lower band runs across the entire rear elevation, while the upper band spans the gable of the cross range. This side includes camber-headed small-pane casement windows, and there was previously a central camber-headed opening that has been reduced for the installation of a 19th century small pane sash window. To the left, there is a lean-to that rises to the level of the band, and above it is a gabled dormer with paired casements and a chimney stack positioned low to the left. Attached to the north-east side is the former stable range, which is stepped down and set back from the main slate-hung gable end, constructed of white-painted brick with a steep slate roof.

The left end facing the road has a stone base up to lintel level, with square paneling and brick nogging above. There is a later gabled porch beside a four-pane casement window.

Although not inspected at the latest survey, a 1990 inspection reported that the 17th century box frame was largely intact above the ground floor, featuring square panelled outer and dividing walls, twin purlin roof trusses with diagonal struts, and stop-chamfered beams and joists. The most notable interior feature is the dog-leg staircase with intersecting balustrades and curvy flat balusters.
