Estate Mill, Gresgarth Hall

The Estate Mill at Gresgarth Hall is a building that has been repurposed as a workshop. It is believed to have originally functioned as a corn mill from 1780 to 1815, then as a threshing mill in 1843, and later as a saw mill. The structure is constructed of sandstone rubble and features a roof made of slate and stone slate. It stands 2½ storeys tall.

The north-east wall displays a central section with three bays, each featuring plain stone surrounds and Tudor-arched heads. The left bay contains windows with glazing bars that intersect beneath the arch. The central bay has a door on the ground floor, with a loading door above that has been blocked to create a window. The right bay includes a ground-floor door and a window above it with brick reveals. To the right of the central section is a ground-floor window with a plain stone surround. Adjacent to the left, beyond a straight joint, is an added section that has two ground-floor doors with plain reveals. The left return wall features external stone steps. Both the attic and first floors have windows with plain stone surrounds, Tudor-arched heads, and glazing bars that intersect. At the rear of the building is a projecting wing. There is no machinery remaining inside.
