This rooftop addition, which creates apartments over the original industrial warehouse building in London's fashionable Shoreditch, is conceived as a contemporary extension which 'floats' over the original. Within this new area, two duplex penthouse apartments and two single bedroom apartments have been created, with large roof terraces to the larger units providing spectacular views over the city. The exterior street frontage at roof level is completely glazed and clad in light silver anodised panels to reflect light down into the courtyard below, to which it is linked by a new lift tower at the rear.
