Attercliffe Sipelia Works

Attercliffe Sipelia Works is a steelworks, now utilized as various workshops, constructed between 1850 and 1855. It was originally built for Eyre, Ward & Co. The building’s construction incorporates brick (painted on the front), rock-faced stone, stone dressings, and roofs covered with slate and plain tiles. The complex is arranged around a long courtyard, with workshop ranges on either side, positioned between the canal to the north and Blast Lane to the south. An office range sits to the east.

The exterior of the office range features a plinth and a first-floor band. It has two storeys and a five-window front featuring 12-pane sash windows with brick flat arches. A central segmental carriage arch, adorned with a keystone, is flanked to the right by a moulded four-panel door with a traceried round-headed overlight, set within a common rusticated corniced surround. To the right of the door is a boarded-up window, and to the left, a 20th-century casement. A single-story building with two windows and a double door is located further to the left. The curved return to the canal displays continuous rock-faced ashlar at basement level and a roll-molded string course. A two-story range exists to the left with regular fenestration featuring a mix of 19th- and 20th-century windows, arranged in a pattern of 2:3:4:5:7:2, with many now blocked. To the right of this, a two-story range with nine windows is followed by a range reduced to a single-story screen wall with twelve windows. The basement has a segment-headed doorway with a rusticated surround. The courtyard side of the buildings is two stories high and includes a blocked cart opening. The left return features a two-story range with segment-headed windows to the left, and a taller single-story range, likely a heavy forge, to the right, with eight tall segment-headed windows—the left one featuring an inserted door—all reglazed in the 20th century. A tall carriage entrance with a steel lintel is situated to the right. The courtyard side of this carriage entrance range, formerly open, now has round cast-iron columns with brick infill and multi-pane glazing above. A square chimney base is present to the right. The canal-side buildings, initially intended for light trades workshops, have brick vaulted floors and numerous flues. The basement contains storage rooms, an engine room, and a boiler house. The interior of the building has not been inspected.

This structure was established as an extension of the nearby Sheaf Works and represents an example of steel trades workshops from the mid-19th century.
