Green Cottage and Millstone Cottage, South of Blackhall Wood Farmhouse, and Threshing Barn to South

Green Cottage and Millstone Cottage, located south of Blackhall Wood Farmhouse, along with a threshing barn to the south, comprise a house and cottage that were formerly a farmhouse and barns. The house dates from the mid-18th century, while the early 19th-century barns were converted for steam threshing around 1840. The house features painted brick walls with stone dressings and a roof made of stone-slate and slate, topped with coped gables and brick chimney stacks. It is two storeys high and has three bays, with both double and single sash windows that include glazing bars. The entrance, which has a plain stone surround, is located in a two-storey brick barn that is now a holiday cottage and features 20th-century windows, a door, and a garage door. The threshing barn is positioned at right angles to the house and has a large cart entrance. Its walls are constructed of mixed sandstone and cobbles, and it has a stone-slate roof. There is a large cart passage leading into the farmyard, which features a rounded arch with a plain stone surround, as well as stone surrounds for the windows and doors. At the outer angle of the barns, there is a boiler-house with a slate roof and an adjoining brick chimney that has a stone string-course and cap. The listing does not include the cart-shed in the farmyard, which has a 20th-century corrugated iron roof.
