The three main office blocks of this polygon house the bulk of Sheffield City Council's offices - Redvers House is the oldest, dating to 1971 - Howden and Derwent House date to 2001. The roads around this block were first formed in the 1880s by the laying out of speculative development plots by architect James Paine at the behest of the Duke of Norfolk (SCC 2002). These streets, shown as proposed on the 1771 Fairbanks plan, were shown as built up by 1795. In 1850 the area was first comprehensively planned by the Ordnance Survey whose survey shows dense urban development of inns, dwellings, workshops and courtyards. Early 20th century map evidence indicates piecemeal redevelopment of the area with significant clearance of residential property. By 1953 the block is occupied by: a 'Packing Case Works', the 'Union Street Picture Palace', a number of metal trades works, a 'Printing Works' and 3 public houses. Legibility of the area's former land use is fragmentary, consisting of the street layout (truncated by the Arundel Gate dual carriageway) and the Roebuck Tavern (shown as a domestic building in 1850).
