This plot represents the former site of the Union Buildings, a 'planned, model industrial' housing development connected to the adjacent Union Grinding Wheel (Atchison, 2002). Demolished in the mid twentieth century and replaced with a modern warehouse. This in turn has been demolished and the site is currently awaiting the construction of the Sheffield Inner Relief Road. Archaeological evaluation in 2004 / 2005 concluded that there was little below ground survival of this complex (D. Saich pers com). Invisible legibility.
