This is the first glimpse of Allies and Morrison's multistorey car park scheme, part of a wider masterplan by the practice in Sheffield's city centre. The 12-storey building will house 520 parking spaces, accommodation for a casino in the ground and basement levels, and retail space leading on to St Paul's Place. The design of the cladding on the car-park levels creates an undefined, patterned surface by using square aluminium panels with two folded triangular sides to produce a tilted face. This will produce a varied pattern of light and dark, with each panel providing a different reflection. The tilted faces also aim to transform the building's appearance at night, with internal light bleeding between each panel, creating a non-uniform composition on the surfaces. The scheme will go on site in November, with completion due in Spring 2008.
