Outbuilding at Ty Gwyn

The outbuilding at Ty Gwyn is a single-storey structure built from white-washed random stone and topped with a slate roof, featuring large stone quoins. The front has openings with segmental heads made of stone voussoirs. A central doorway leads to a through-passage and is lowered, containing split doors with a segmental head. To the right, there are two openings, and to the left, one opening, arranged asymmetrically, featuring late 20th-century two-light wooden casements with quarries; the two windows on the right may have originally been narrow doorways. There are ventilation slits on the far left.

The rear elevation has a doorway with a boarded door under a timber lintel, with a small opening above that likely served as an overlight or for timber boarding. There is a small late 20th-century two-light casement on the far left and a very small light to the right of the doorway, with ventilation slits on each side. The west gable end has a two-light window similar to the front, under a segmental head of stone voussoirs and offset to the left. The east gable end features an earlier two-light wooden casement without glazing, offset to the right. The interior has not been inspected.
