Pen-y-llan

Pen-y-llan is a building featuring a ground floor constructed of brick and an upper floor made of square-panel timber framing, topped with a slate roof. The brick on the lower floor likely replaces original stone. The timber framing consists of three panels high with long straight tension braces, and the top panel may have been added when the roof pitch was lowered. The building has boarded doors with lean-to canopies and timber windows with panes, some of which were replaced in the 1990s to match the original design. There is one small gabled dormer on the front and three on the rear. It includes a four-flue brick stack and a two-flue gable stack, both made of brick.

Inside, there are back-to-back fireplaces in the hall and parlour, featuring twin chamfered spine beams. The hall fireplace contains a bread oven. The service room in the third bay has a gable stack and a single ogee-stopped spine beam, along with an additional oven beside the fireplace, which has been altered. The staircase is located in the outshut behind the main stack.
