Description
Bwlch-du is a long, single-storey small farmhouse constructed of whitened rubble with a corrugated asbestos roof, which was probably originally thatched. Modern purlins are visible at the gable ends. The farmhouse consists of two sections: a living area with two windows on the right and a brewhouse section with two windows on the left, separated by a large central chimney. The brewhouse features weather-coursing and 20th-century brick cornicing. There are 20th-century boarded doors, with the brewhouse section having small, plain late 19th-century or early 20th-century sliding sash windows, while the main section has a similar sash window on the right and a larger 12-pane sliding sash window on the left. All windows have projecting slate sills. The interior was not inspected during the survey.
