Description

Llwyn-ynn Hall is a 17th-century building featuring an L-shaped timber-framed structure and a stone link block of uncertain date. The timber-framed section is elevated on a high stone plinth and has gables facing south and east, topped with a slate roof that includes a dormer and a tall stone chimney. The timber framing consists of square panels that are three panels high, with top corner braces. The corner posts of the south-facing gable are notably jowled. Above the tie beam, the panels are arranged diagonally. The building has modern windows, and the timber frame on the left side of the main south-facing gable shows significant decay. There is a single-storey annex located in the southeast angle. The interior of the surviving part is not accessible.
