Farm buildings at Dolaugwyn

The farm buildings at Dolaugwyn consist of a barn and a cowhouse, built in the 19th century. The barn is constructed from roughly coursed boulders, including some igneous rock and white quartz, with the joints galetted. It features a corrugated iron roof that has replaced the original slate, and it has a raised boulder-coped gable on kneelers at the north end. The cowhouse range is made of coursed rubble on a boulder foundation, topped with an old slate roof that is hipped at the return over a later link building of similar construction. Together, the barn and cowhouse form an 'L'-shaped plan, with the barn running approximately north-south and the cowhouse extending east-west at the south end.

The barn has two pairs of small double cart doors with timber lintels and two levels of slit vents in each bay. The north gable end has been rebuilt and features a later open-fronted lean-to structure. A modern large-span building with a sheet roof covers the rear of the barn range. The cowhouse range includes five stable doors alternating with square ventilated windows, with some of the doors converted into windows.

Inside, the barn consists of five bays, each with a span of about 6 meters, supported by four pairs of full cruck trusses that are halved at the apex. These trusses have high-set collars and originally featured trenched tie beams, although these have been replaced with later tie beams set higher. One couple of trusses has been replaced with a conventional tie beam truss on an internal pier, and another cruck blade has been cut off at tie beam level on the west side. There are two tiers of purlins, and the central threshing floor is paved with slate. The cowhouse range was not accessible during the inspection.
