Sebay Mill

Sebay Mill is a near-symmetrical, L-plan mill built around 1854, featuring 2 and a half storeys and four bays. It has a later two-storey lean-to addition at the internal angle on the rear. The exterior is made of roughly coursed rubble, with gables that have block finials and attic windows positioned close under the eaves.

On the south elevation, there is a large timber sliding door at ground level in the bay to the left of the centre, a boarded door at the first floor, and a small window in the attic above. Each bay to the right has a window on every floor, while the bay to the left also has windows on each floor.

The west elevation includes a window at ground level and an attic window in the bay to the left. There is a boarded door set to the left at ground level in the gabled bay to the right, with a window above it at the gablehead.

The north elevation is a four-bay arrangement, with windows grouped in pairs. There is a window at ground level and a small window at the first floor in the recessed lean-to block to the left. Each bay to the right has a ground-level window, with a gablehead window above.

On the east elevation, there is a window at the first floor with an attic opening above in the gabled bay to the left, while the lean-to bay to the right has a window on each floor.

The mill features timber-framed windows, some of which are blocked. The roof is covered with purple slate, and there are stone ridges and stone skews. The interior was not seen during the last inspection in 1998.
