Barn at Tan-y-Foel

The barn at Tan-y-Foel is a long structure built from rubble, topped with an old slate roof. The main section, which consists of four bays, is located at the downhill end. It features a wide 20th-century entrance on the left with boarded double doors that reach the eaves. To the right of this entrance, there is another opening with studded and boarded stable doors, accompanied by a recessed 19th-century slate lintel. A small square light is positioned to the right, along with a ventilation slit beyond it. Additional ventilation slits can be found at the rear and on the lower gable. On this gable, there is a 19th-century lean-to that is slated and has a boarded door set in a pegged frame.

At the upper end of the barn, there is a 19th-century addition that is flush with the main block and shares the same roofline. This addition originally had three stable or byre entrances with similar lintels, but only the leftmost entrance remains open; the right entrance is blocked, and the central opening has been converted into an 8-pane window. In the gable apex of the upper end, there is a 4-pane window with a recessed lintel.

Inside the primary section, there is a four-bay layout featuring three pairs of steeply-pitched cruck blades. The original pegged collars and tie-beams have mostly been removed, as have the purlins. A later 19th-century or 20th-century roof with a shallower pitch now covers the barn, and the 19th-century raising is clearly visible from the interior. The uphill extension consists of two bays and has a plain collar and tie-beam truss, although the collar has been removed.
