Description

Pen-y-bryn is a 1½-storey former farmhouse that originally consisted of four units and is situated on a slope, running east to west. The house now faces south towards a small walled raised forecourt. The front and left sides are timber-framed, while the right bay features stone walls. At the rear, there is a modern stone-walled low lean-to extension. A large chimney is located at the west gable, and the roof is covered with slate and has a tile ridge. There is also a large chimney opposite the main entrance, which has ribbed double stone shafts.

On the south elevation, the timber-framed section includes two five-light timber mullion windows below and two four-light timber-mullion dormer windows above, featuring slightly jettied dormer gables. To the right, there is a doorway with a Tudor arch and a restored door.

The lower bay is constructed from small slate uncoursed masonry with sandstone quoins. The east gable elevation has small windows with segmental heads and no sills, and the lower window is made of cast iron with three small panes.

The interior has a two-bay hall plan with a cross passage below and two inner rooms above, showcasing superb original carpentry. The main truss over the centre of the original hall consists of base crucks with an arch-braced capping collar beam and cusped timbering above. Cusped windbraces support the chamfered arcade plate, and the soffit of this truss is decoratively carved. At the upper end of the house, there is an aisled crossframe with doors leading to the inner rooms and post and panel infill. The spere truss at the lower end is carved like posts with caps, and its spere posts are designed as four colonettes separated by keels, similar to those at Hafod in the same community. The end frames are also of an aisled form, with butt purlins and no ridge beam.

When the house was altered to a storeyed form, likely in the early 17th century, it was fitted with a staircase described by Hughes as striking, featuring carved newels with elaborate finials and wide balusters designed to follow the pitch of the stairs, all carved on every face.
