Trevillet Mill

Trevillet Mill is a mill and millhouse, converted into domestic use and a cafe, dating back to the 18th century, though built on the site of a 15th-century mill. The building is constructed of slate stone rubble with a slate roof featuring gable ends. There are two brick lateral stacks to the taller main mill building, and gable ends with stone rubble end stacks to the two lower ranges, which originally served as domestic accommodation. The mill has a rectangular plan and stands three stories high, housing two pairs of millstones. An overshot wheel originally stood on the opposite side of the mill, and a loading bay with a hoist is situated in the right-hand gable end. Brick lateral stacks are present on the front and rear of the left side of the building.

The left-hand domestic range consists of a single-room plan with heating provided by an end stack. The second domestic range, also of a single-room plan, extends forward on the front left and appears to have originally been heated by a projecting stone rubble stack. This stack was later blocked in the late 19th century, and a fireplace was inserted on the rear wall, served by a brick lateral stack from the mill building. The mill building is three stories high, while the domestic wings are each one and a half stories high.

The front elevation features a projecting wing on the left with a stone rubble end stack, and the mill building behind. C20 two-light casement windows are set within the two gabled half dormers. The lower wing on the left has a possibly reused ovolo moulded lintel above the ground-floor two-light casement, and a C20 two-light casement in a gabled half dormer on the first floor. A C20 extension is located in the angle between the two domestic wings. The right-hand gable end of the mill has C20 fenestration in the loading bay, on the third floor, and the slate hood and winch above the loading bay are intact. The rear elevation shows remnants of a mill race, the pit, and part of the wheel shaft.

Inside, the mill machinery, dating to the late 19th century, has been restored and includes two pairs of balanced millstones and a sack hoist. The left-hand wing features closely spaced, roughly chamfered ceiling beams, while the front wing has a circa mid-19th century chimney-piece. The mill is documented back to 1472, and a 19th-century painting of the mill by Creswick, entitled 'The Valley Mill,' exists.
