Description

The Water-Mill at Sadborow Mill is a detached water mill dated 1827, as indicated by the keystone of the top right window. It features rubble walls with brick quoins and dressings, and has a hipped Roman tile roof from the 20th century. The building is rectangular in plan and consists of two storeys.

On the exterior, there are three casement windows with renewed wooden frames and cills, set beneath segment-headed arches with stone keys and some burnt headers. Near the center of the ground floor, there are two 'stable-doors' with brick jambs and wooden lintels. One of the stable-doors has a large iron hook above it, and there is a tall built-in wooden buffer beside one of the ground doors.

At the rear, the mill features a 22-foot overshot wheel that operates at 6 revolutions per minute, originally driving two millstones and later three. Inside, there are 19th-century wooden partitions and doors, a stone floor, and two extant millstones along with the full milling apparatus, including a winnowing box and a mixing room (though the scales are not original to the mill). The bin-floor includes a platform and chutes. The machinery is notably complete, and the mill was operational within the last two years, although full operations ceased in the 1950s. A mill pond is located behind the building, fed by a spring from the Sadborow estate.
