Unthank Mill, Houses And Cow House Attached

Unthank Mill, house, and cow-house, now all functioning as a cow-house, date from the 17th, 18th, and 19th centuries. The building is constructed of coursed sandstone rubble with tooled and pecked ashlar dressings and features a stone-flagged roof. It is arranged in an L-plan, with two storeys, four bays, and a one-storey wheel-house on the right. A two-storey addition from the 19th century projects from the left side.

The mill section on the right has a tooled surround to a partly-blocked central doorway, with flat stone lintels over a boarded loft opening and flanking windows, the left window being smaller. The wheel-house features a wooden lintel over its door. The 19th-century addition has pecked stone lintels and projecting stone sills for the ground floor and first-floor openings, which are boarded up. The low-pitched roofs, with parallel ridges, have three ridge chimneys, two of which are truncated. The right return rear wing includes a plain stone surround to a Dutch door and flanking windows.

Inside, there is much machinery, including a pit wheel, with all visible gears and cogs made of whitish wood. There are two bed-stones on the floor above, and while the water wheel is missing, a sluice for the undershot is partly surviving. The cow-house at the rear has two internal boarded partitions and three V-shaped plank feeding troughs between the stalls.

Outside the mill, there is one upper stone on the ground. The building was noted as decaying and derelict at the time of the survey, although some roof timbers have been renewed.
