Dated on stylistic evidence to the later 20th century, these buildings, which include offices, warehouses and some light industrial units, replaced an area of grid iron industrial / residential development dating to the early 19th century. The area was cleared and the earlier street pattern overbuilt at the time of construction of St Mary's Gate to the north (HSY1769). The area lies to the immediate east of the site of the hamlet of 'Little Sheffield' and was depicted as piecemeal enclosure fields on a Fairbank sketch map of 1789 (reproduced in May, 2003 illus. 3). The area was laid out as streets by 1818 (ibid, 3) with a pattern typical of the late 18th and early 19th centuries in the city centre, with streets made up of predominantly back to back housing with small courtyards a regular feature - often containing workshops of various sizes. Between 1851 and 1891 the small trades being carried on in domestic scale workshops (ibid, 4) were joined by larger dedicated works complexes. From WW II to the near present the earlier buildings of this area were progressively demolished - resulting from a combination of slum clearance, bomb damage and manufacturing recession. Invisible legibility of street pattern and earlier buildings although there may be good archaeological potential for remains of the 19th century development in patches throughout this area.
