High Birk Hat Farmhouse, Attached Barn And Byre

High Birk Hat Farmhouse, along with its attached barn and byre, dates from 1741, as indicated on the door lintel, with some alterations made in the mid-19th century. The buildings are constructed of squared rubble and feature stone-flagged roofs and stone chimney stacks. The farmhouse is a two-storey, four-bay structure with a replaced four-panel door and a three-pane overlight in the second bay. The door is set in a flush surround and has a lintel inscribed with "17 IID 41." The windows have flush lintels and projecting chamfered sills, including a small 12-pane sash above the door and flanking 16-pane sashes. The roof has coped gables and shaped kneelers, with end stacks that have top bands and water tables.

The two-storey barn has a blank front wall and a coped left gable. It is accompanied by a lower three-bay byre and loft. The byre features a central boarded door in a flush surround, flanked by partly-glazed hit-and-miss windows, with a boarded opening above the door. It has a low-pitched roof, and the right return of the byre includes an external stone stair leading to a boarded door.
