Large steelworks complex now covering most of the area of this polygon. "The part adjoining the [goit] comprises a long range of mid 19th century brick buildings on a stone base, the largest of four storeys with broad windows on the upper three" (Harman and Minnis 2004, 168). Along the Green Lane frontage are early 20th century buildings. The site seems to have developed through expansion and intensification from a number of courtyard works shown on the 1851 OS 60 inch to the mile plan probably after the acquisition of the site by Ibbotson Bros (along with the former workhouse (HSY1780) to the south west) in the 1860s. Significant legibility of earlier phases.
