Description

Plas-y-darren is a house constructed with painted stucco and slate roofs that overhang at the eaves and verges. It features three rendered chimneys, one at each end and one on the ridge towards the right end. The building has two storeys and a long facade facing the garden, with windows spaced irregularly. The right end of the house has raised quoins and a ground floor canted bay window with 2-4-2 panes, topped with a modillion cornice. Above this bay window is a renewed 4-pane sash window set in a plain raised eared surround. To the right of the ridge chimney is the main entrance, which consists of two arched glazed panels leading to a 4-panel door with an overlight, all within a later 19th-century rock-faced stone porch featuring a Tudor-arched entry, stone voussoirs, and fretted bargeboards on the gable. Next to this is another first-floor four-pane sash window that matches the one to the right, aligned with a broader canted bay window. To the left, before a projecting dairy outshut, is a third first-floor 4-pane sash window. The front wall is made of rubble stone and includes a first-floor casement-pair window.

At the rear, there is a stair light to the left of the centre and a 20th-century addition. Inside, the entrance passage and stairs are situated between a small parlour on the right and a large middle room in the centre, with the kitchen at the left end and the dairy projecting. The hallway features a panelled hall arch and a staircase with later 19th-century turned balusters and newels topped with ball-finials. The interior includes 19th-century four-panel doors with chamfered and stopped borders. The parlour has a moulded plaster cornice, a ceiling rose, and a marbled fireplace with an iron grate and inset painted tiles. The large centre room has a stone-flag floor, shutters on the bay window, a moulded cornice, and a 19th-century chimneypiece with brackets supporting the mantel-shelf. There is an arch over the doorway to the stair hall. The kitchen originally had back stairs, which have since been removed, and features an arch over the doorway to the centre room. The kitchen has a joisted ceiling, and the fireplace includes a bread oven to the left, with a recess to the right that was used as a smoking chamber.
