Description

Bryn-Dwr is a two-storey building with a broad front featuring two windows, finished in scribed render and accented with rusticated quoins. It has a slightly undulating slate roof, bracket eaves, and a very tall central chimney stack made of rendered brick. The first floor has recessed nine-pane sash windows, while the ground floor has twelve-pane sash windows, all positioned slightly to the right. The entrance features half-glazed double doors with some coloured glass, framed by a doorcase with a bracket pediment and pilasters. There is a finial on the left gable end, which also has rusticated quoins. A Tudor label is present above the twelve-pane sash window on the first floor, with a similarly glazed splayed bay window below. To the left, the gable end of a parallel range at the rear is set back, along with a stepped back cross gable.

Inside, the building has a lobby entry plan. The main room is located to the left, featuring a fireplace with a deep lintel and a blocked stone staircase. The cross beams intersect at the center with a deep chamfer. Recently uncovered during an inspection in January 1989, the rear of this room retains two earlier walls; the inner wall has 19th-century Gothic wallpaper, possibly indicating a former ecclesiastical use of the building, while the outer wall is half-timbered over a rubble base, with wattle and daub still visible. The kitchen on the right has a broader fireplace, a higher ceiling, and a slate flagged floor.
