Threshing Barn and Additions North of High Town House

This is a threshing barn and its additions located north of High Town House, dating from the early 19th century with later 19th-century modifications. The barn is constructed from dressed stone and has a corrugated-asbestos roof, while the additions are made of coursed rubble with slate roofs. The building has a linked T-plan, featuring the threshing barn with an extension on the right side, and a byre at right angles to the barn, which has a lean-to barn attached at the rear.

The threshing barn is two stories high and has five bays, with central opposed elliptical archways that feature paired boarded doors. There are two rows of breathers and a blind pointed archway on the left return. The two-story, two-bay extension on the right return includes 20th-century garage openings and a small boarded window above, with a hipped roof on the right side. The two-story, three-bay byre, located to the right of the barn's archway, has a central Dutch door with a boarded loft opening above, set in surrounds with alternating jambs. At the rear of the byre is a lower two-story lean-to barn. A single-storey garage on the gable end of the byre is not considered of special interest. The building is included for its group value.
