Mill to South of Highbury Works

The building is a paper mill, later converted into a tannery, and is now vacant. It was constructed around 1800, with additions made in 1844 and 1857, and features later alterations. Originally built for Thomas Martin, it was converted for Samuel Smith. The structure is made of dressed stone with ashlar dressings and has a hipped corrugated sheet roof that includes eight circular metal ventilators. The building is L-shaped and has three storeys.

The east front has 13 bays, with a pair of double doors on each floor to the right. The ground floor has various blocked windows, while above it features an off-centre loft door, four 2-light windows to the right, and seven similar windows. The upper level has 12 openings, which originally had louvred shutters but are now partly blocked, with 3-light upper windows. The left return to the south has two bays with similar window arrangements.

The west front consists of 12 bays arranged in a 5:8 pattern, with the left block projecting. A set-back wing to the right has eight windows, with eight more above, most of which are blocked. The upper section has eight openings that originally had louvred shutters but are now partly blocked, featuring 2- and 3-light upper windows.

Inside, the building retains wooden beams and floors, along with original wooden staircases. It was initially built as a paper mill and later converted into a tannery.
