Former Upper Tin Mills

The Former Upper Tin Mills is a building that has been repurposed as a builders' merchants. It features a large triple-roofed shed that incorporates parts of the original double-roofed range. The northeast gable ends, party wall, and southwest walls are made of original rubble stone, while the former have been raised with 20th-century concrete blocks. The roofs are all from the 20th century, with the northwest parallel range being an addition that has mostly been rebuilt during the same period. The triple roof is covered with corrugated metal.

On the northeast end, there are three broad low-roofed gables; the left two are original but have had their eaves rebuilt in blockwork. The left gable features a broad cambered-arched entry framed in brick, likely from the 20th century, with an arched window above it. The middle shed has similar arched windows, with three openings below and one above, and the bricks are quadrant-curved. The right shed is an addition and is mostly constructed of blockwork. The side wall has been extensively rebuilt in blockwork.

The party wall between the two principal sheds includes a series of semi-circular double-brick arches, arranged with two large arches flanking four smaller ones, and two additional small arches to the right of the second large arch. Some of these arches have chamfered surrounds. There is also a series of round-arched openings in the outer wall of the southeast shed.
