Caruso St John Architects have just unveiled the new Nottingham Contemporary Arts Centre, which takes inspirations from both the physical nature of the site and the architectural character of the warehouses in the lace market near to it. The most interesting feature though is the lace moulds for the external facade, which have taken original lace patterns and machine milled by computer control an original, from which a mould can be taken and then several concrete precast units can be formed.
