Harewalls farmhouse is a remodelled bastle. It dates to the late16th or early 17th century and is built of large roughly squared blocks with massive corner stones. The walls are said to be 1.35m thick. The byre doorway is now blocked as is a small basement slit vent. The original first floor doorway can be seen as well as a unique keyhole-shaped gun loop cut through a single block of stone, both features are now blocked. Later windows and doorways have been inserted. (1-3)
