Barn and byre range at Coed Hir

The barn and byre range at Coed Hir consists of two separate units built into a slope. The upper unit, which is the byre, features limewashed rubble walls and a Welsh slate roof. It has arched doorways at each end facing the farm track, with a stone-tiled hood to the left and a wide stone buttress in between. There is a loft door at the gable end, and while there are no windows at the rear, the roof extends to form a hood.

The lower unit has a half hipped roof that combines pantiles and stone tiles, extended on both sides to create porches for the double doors. The stone tiles may have been reused from the earlier part of the building located uphill. The south side has been extended with outshuts to the level of the porch, resulting in a catslide roof. There are ventilation slits on either side of the porch and in the gable end, with a stone divider in the middle, as well as additional small ventilators in the outshuts.

Inside the byre, some stone stalls and a central feed passage remain. The barn consists of four bays supported by pegged and bolted tie-beam trusses and three rows of trenched purlins. It features a stone threshing floor with stone kerbs and a cobbled porch floor. The outshut on the right is believed to have been used as a bull pen, while the one on the left served as a calf shed.
