West Barn at Purkis Farm is a remarkable example of Britain’s agricultural heritage, rooted in nearly a millennium of threshing barn tradition. These barns were vital to rural life, originally built to protect and process grain harvests. Over centuries, they evolved from simple hand-threshing spaces to sophisticated steam-powered facilities. Constructed between 1841 and 1876, West Barn reflects the shift from manual labour to mechanised farming. Its three-bay timber frame, made almost entirely from reused oak and elm, showcases Victorian ingenuity. Originally clad with weather-boards and lath and plaster panels, the barn features nailed interrupted studwork and wrought iron bolts. In the 20th century, West Barn was converted into a stable, with homemade harness trees still visible on the eastern wall. Later, it served as a loading area for milk churns and the adjacent West Shelter became a milking shed. Despite its age, the barn retains much of its original structure, including threshing boards and housing grooves, making it a rare and well-preserved piece of agricultural history.
