Shown on the 1838 Tithe Map, the asymmetrical plan of the farmhouse and the change in masonry construction between the ground and first floors suggest a building of C18 or earlier origin, substantially remodelled in the early C19, with the front ground-floor windows changed again in the mid-C19.


3-bay, 2-storey rectangular plan, aligned roughly north-south with full-height range at right-angles to rear on north forming L-plan. Roughly coursed rubblestone on ground floor giving way to larger, more regularly coursed and dressed slabs above; graded slate roof. 3-window front has irregularly spaced fenestration, left and centre windows closely set, with unhorned 12-paned sashes on first floor and 4-paned sashes on ground floor, all with slate cills. Central entrance has prominent C20 gabled porch; integral end stacks, right roughcast.


Interior not inspected at time of Survey.
