The 640 residential unit building complex is comprised of a singular universal block, interconnected on two levels. It thereby suggests a permeable, notional, perimeter block. Each block is connected to the other as a bridge, which also produces a roof terrace on the free, upper surface of the block below. These terraces are for the leisure use of the residents. On the top-level, the roof terraces have gallery-type rooms above the lift cores with varying functions – a library, a gym, a nursery, a boiler room and a gallery.
