Description

This is an outbuilding located southwest of the house at Aberdeunant, constructed from whitewashed rubble stone and topped with a slate roof that has a shorter pitch at the rear. The building is a narrow single-storey range featuring a square window and door on the left, a central door, and two very small square windows, with the right window situated in a blocked door. The structure has timber lintels. There is a door at the south end, and a small gabled outhouse at the north end, which has curved corners, a corrugated iron roof, and an entry on the north side.

Inside, the roof trusses are made of reused timbers, with some remains of scarfed crucks. The outbuilding contains three rooms: the southern room has 20th-century feeding troughs, while a low block wall separates it from the middle room, which features a rough cobbled floor. The northern room, which was used as a dairy, has a low brick wall and a cupboard in the blocked northern window.
