Warehouse, Former Premises of Marble Mosiac Company

This former warehouse, built in the mid-19th century, was the premises of the Marble Mosaic Company. It is constructed from pennant rubble and features a brick and steel truss roof covered with corrugated sheets. The building has a rectangular open-plan layout divided into three sections and is a single storey with a nine-window range. There are three gables with a plinth, each featuring three rock-faced semicircular vehicle arches, which have been infilled to plinth height with brick and 20th-century glazing. Four 20th-century openings have reinforced concrete lintels above the 3rd, 5th, 7th, and 9th arches. Below the smaller arched windows with 20th-century glazing, there is a first-floor string, along with a small string above. The roof has been raised in the 20th century, with brick walls and gables added. The side elevations include six upper semicircular arches. Inside, there is an inserted first floor supported by steel stanchions in the middle shed. Historically, this building may have served as the Coke House for the Avon Street gas works and could have later been part of James Gibbs' Vitriol Works, as indicated in Lemarr's View of 1887.
