Description
The Mill is a two-storey house with a later rear wing, constructed of whitewashed rubble stone and topped with a slate roof featuring a stone stack on the left side. The front has three windows, which are offset to the right, consisting of 19th-century two-light casements set under segmental heads on the lower storey and extending up to the wall plate above. There is a central boarded door.
On the left gable end, there is a shallow oven projection, a blocked door at the lower left, and an inserted window above. The right gable end features a two-light casement window at the upper right and a recently added window below it, along with similar windows on the side wall of the rear wing. The rear wing has a gabled two-span roof, and its rear wall contains two windows with 19th-century two-light casements in the upper storey, as well as a lean-to at the lower left with two-light casements and a boarded door.
The lower storey is divided into two units and includes a fireplace stair.
