Scotts Mill House, Fettykil Paper Mill, Leslie

Scotts Mill House, located at Fettykil Paper Mill in Leslie, is an earlier 19th-century lint mill. It is a two-storey building with an attic and a single-storey extension, featuring a rectangular plan and seven bays, situated on sloping ground to the south. The structure is built of whinstone rubble with dressed quoins and is currently used as a store.

On the north elevation, there are seven windows on the ground floor, and an altered door on the outer left at the first floor, which is accessed via a modern footway bridge from the first floor of the opposite building. To the right, there are three additional windows and a modern flat-roof linking extension over two bays, with a window on the outer right.

The east elevation shows a blocked opening with a rubble lintel to the left of center, above a narrow projection that slopes away to the south, indicating evidence of a low-pitched roof above. There is a modern single-storey brick extension to the left, a small window on the outer right at the first floor, and a gablehead window in the center with a small square opening above, possibly for ventilation.

On the west elevation, there is a centrally located sliding garage door at ground level, with a door to the right in a slightly recessed rubble extension that adjoins a modern brick extension on the outer right. A gablehead window is also present in the center.

The south elevation features six visible windows at the first floor above the pitched roof of the brick extension, along with a corrugated tin link roof to the outer left and three rooflights to the left of center.

The brick extension to the south has a lower profile with a piended, corrugated-iron roof. It is constructed of Flemish bond red brick, featuring six vertical open-work sections corresponding to the windows in the earlier building on the south, three on the east, and a narrow horizontal section spanning the entire south elevation close to the base.

The interior includes a stone wheel stair with a wooden handrail at the top, five relatively narrow cast-iron columns, approximately 2.5 inches in diameter, likely dating from around 1820, as well as larger cast-iron columns with curved brackets. Some lath and plaster work is visible in the attic.
