Bryn Dinas

Bryn Dinas is a 1½-storey, three-window house built of rubble stone, with cement rendering on the front and left gable end. It features a graded-slate roof with a coped gable on the right side, a central stone square chimney stack, and a rendered square stack on the left. Most of the openings date from the late 19th century. To the left of center, there is a recessed panel door beneath a simple slate hood, flanked by four-pane horned sash windows and a small casement window further to the right. Three gabled dormers, each with four-pane horned sash windows, are present. The right gable end has a loft door, while the left gable end has four-pane sash windows, smaller ones in the attic, offset towards the rear.

At the rear, the house has a three-window layout with a one-storey wing on the right that includes a sash window and a half-glazed door. The hall and inner room each have an inserted two-light small-pane casement window, and there is a small stair window to the right of center.

The house has a three-unit plan. The entrance features a residual cross passage with a rear doorway that now opens to the rear wing, opposite the front doorway. The left room retains a cross beam with run-out stops. The hall on the right has a joist-beam ceiling, with the spine beam featuring fillet stops. The large fireplace has a timber lintel, and to its right is a stone stair. Two former inner rooms are separated by a 19th-century post-and-panel screen, with the dairy on the left retaining slate slabs. Two half cruck trusses are visible, with the central arched-brace truss being finely moulded and featuring a moulded boss, indicating it was once the open truss of a two-bay hall (any ornamentation above the arched brace is concealed by plaster). The second truss, located in the inner rooms, is plainer and has a collar beam. The lower storey has a flagstone floor.
