Description
Nos 1-3 Plas Brondanw Cottages is a rectangular gabled block built in the 19th century, featuring two stories with an attic and a raised ground floor on the garden side. The structure is made of rubble and has a shallow-pitched slate roof with stepped gable parapets. A plain central chimney with weather-coursing is present.
The western gable, which faces the gardens, is symmetrical and has a wooden Tuscan doorcase that is applied decoratively at the center of the ground floor. This doorcase is topped with a moulded pediment and features a narrow 8-pane window above it. In front of the doorcase, there is a raised platform with stone steps leading to the garden level on both the right and left sides, with an arched recess below. Flanking the doorcase are two recessed 16-pane sash windows on both floors, all set within reduced openings. At the apex of the gable, there is a small 12-pane sash window with a segmental niche above.
The northern side has modern 12-pane windows and a 15-pane glazed door to the right, although all openings have been altered. The eastern gable and the ground floor of the southern side also feature similar doors and windows, while the first floor has a 9-pane steel-framed, arched-headed window from the mid-20th century.
The interior was not inspected during the survey.
