Bwlch-y-Maen

Bwlch-y-Maen is a building constructed from roughly coursed rubble with a slate roof, facing southeast. The first floor features three 19th-century windows with 20-pane hornless sash glazing, along with a smaller 12-pane sash window to the left. On the ground floor, to the right, there is a doorway that appears to be original, topped with a stone lintel. To the left of this doorway is a window that was formerly the main door, which has a shaped stone head above it. Further left, there is another doorway that was a former window, and an additional window with a deep stone lintel.

A stone rectangular chimney to the left indicates the limit of the original house, which was extended to the left, likely in the mid-19th century, obscuring a projecting 17th-century chimney in the gable. The extension aligns with the main block and includes a stone stair leading to a first-floor doorway, with a small pane window to the left. There is also a broad opening for a cartshed to the left of the stair. The ridge of the roof has an inserted 19th-century brick chimney stack. The eastern gable features a projecting shouldered chimney with a tall, diagonally set square stack, and a first-floor window to the right of the chimney, while the left window has been blocked. Below, there are lean-to pigsties.

At the rear, there is one window on the first floor and, on the ground floor to the left, a small window under a simple stone lintel, along with a doorway that has a shaped stone lintel. At the west end, there is a 19th-century dairy outshot built with matching materials, featuring a tall brick diagonally set chimney stack and a broad doorway facing southwest.

Inside, the ground floor has a ceiling with five bays supported by six chamfered beams with moulded stops, and most of the original chamfered joists remain. A wide fireplace in the southwest corner has a chamfered cambered lintel. The roof contains three trusses, which are probably original, although some tie-beams are more recent.
