Description

Pen-Y-Bedw is a building constructed with roughly coursed rubble masonry and features 19th-century slate roofs. The northern house has a large square chimney on the left and a smaller gabled brick extension. The first-floor windows are set at the eaves, with a 2-light casement on the left and a 4-pane square sash on the right. There is a roughly central front door located under a gabled brick porch, with a 3-light casement to the left and a vertically-proportioned window to the right. The southern house has a rectangular chimney and two 2-light casements on the first floor, with a smaller sash to the right; the first-floor windows are also set at the eaves. The front door is roughly central, with a 2-light casement to the left and a broader 3-light window to the right. At the rear, the northern house features a lean-to extension dating from around 1800.

The houses are extended to the north with a 2-storey lofted stable and cartshed, built in the late 18th or early 19th century. This structure is made of random rubble with a thin slate roof and simple stone lintels over the openings. The west-facing side has a broad cartshed doorway and a small square window for the stable on the left. In the northern gable, there is a square-headed door leading to the stable and stone steps leading up to the loft doorway. At the rear, stone steps at a right angle lead up to the cartshed loft.

The northern section is said to have a roughly hewn main ceiling beam and a deeply splayed fireplace with a large wooden lintel supported at the ends by corbels. There is a square stone staircase to the right. The southern section is noted for having a more massive exposed ceiling beam that is chamfered with intermediate stops, similar to those found at Coed-y-Ffynnon.
