Barn and cow house at Tyncoed

The barn and cow house at Tyncoed form an L-shaped structure, with the barn being timber-framed and featuring weatherboarded walls on the south and east sides, while the north wall is made of corrugated iron. The barn has a slate roof that is hipped to the right (east) and is open on the west side where a stable was previously attached. Facing the yard, the wagon bay still has one of its 19th-century split boarded doors with strap hinges, while the opposite side retains one door and part of another.

On the south side is the lofted cow house, which faces a pitched-stone cattle ramp on the west side. This cow house is constructed of brick with blue-brick dressings and quoins, topped with a slate roof. It features openings with segmental heads and has six doorways, most of which have split boarded doors. These doors lead to various areas, including cow stalls, a byng, two more doors to cow stalls, another byng, and a bull shed. Between the windows, there are four wood-framed windows, three of which still have wooden vents. The cow house also has two segmental loft openings, with the left-hand opening located beneath a gablet. The gable end includes a single boarded door, which may lead to a calf cot. At the rear, there is a continuous outshut that houses calf pens, featuring four windows with vents.

Inside the barn, there is a five-bay roof supported by tie beams and raking struts, with principals added when the barn was heightened. The threshing floor retains its original flagstones.
