Ty-yr-ychen, also known as Sker House farm buildings.

Ty-yr-ychen, also known as Sker House farm buildings, is a long range structure aligned east-west, constructed from local rubble limestone with slate roofs that rise in two stages towards the east. The western gable contains remnants of medieval architecture, likely part of a chimney breast from a now-lost building to the west. This range serves as a seven-bay farrowing house extending east from the gable, believed to date from the 17th century, with the middle section converted into a cow-house in the 18th century. It features one wide cart opening at the eastern end, two doorways, and two windows, all with cambered heads, boarded doors, and small-pane glazing. The northern side has slit ventilators with diagonally set projecting capping stones.

At the eastern end, the barn has slightly projecting central porches on either side, with cambered brick arches covered by an extension of the roof and tall boarded doors on the northern side. There are three staggered slit ventilators on each side of the central bay, some of which are blocked. The upper section of the southern door is obstructed by a later arch and cut-down boarded doors, with similar slit ventilators present.

Adjacent to the barn is a feed store featuring a single door opening on each side. The farrowing house range at the eastern end boasts six fine open trusses with chamfered principals that rise from within the walls, with later applied collars supporting three tiers of trenched purlins. Former tie beams are visible in the entrance bay, and the gables have splayed windows.

The adjoining building includes a splayed opening with a round arch, possibly a medieval window. The barn itself has four bolted A-frame trusses resting on wall plates and a flagged threshing floor, with evidence of a former inserted floor at the western end. A gable window with splayed jambs connects to the adjoining building, and there are doorways with curved timber lintels at each end of the threshing floor.
