Barn Approximately 18 Metres South of Burnthouse Farmhouse

This is a 18th-century threshing barn with an adjoining byre, located approximately 18 metres south of Burnthouse Farmhouse. The structure is built of cob on stone rubble footings, with some patches of 19th and 20th-century brick, and features a thatched roof. It is a long block that faces the farm courtyard to the northeast and is built down a slope, with the byre on the uphill left end and the barn downhill to the right.

The barn has central opposing doors leading to the threshing floor, while the byre has a brick-lined doorway that appears to have been reduced in width in the 19th century. It contains a 19th-century door with a contemporary loading hatch directly above and an unglazed window to the right. The barn has large full-height doorways on each side, both flanked by short midstrey walls, and features 19th-century double plank doors, each split into two flaps. The roof is hipped at each end, with the eaves extending down slightly as a hood over the barn doorway.

Inside, the two parts are separated by a cob crosswall. The byre has two large oak crossbeams with roughly-made soffit chamfers supporting the hayloft, while the barn is open to the roof. The structure consists of seven bays in total, with three in the byre and four in the barn. The trusses are A-frames on tie beams with spiked lap-jointed collars and X-apexes. This barn is a rare example of a traditional Devon farm building that still retains its thatched roof.
