The 256m high Helical tower on Heron Quay is mixed use, consisting of retail, co-working offices, business incubator, apart-hotel and residential apartments. These are organized into horizontally zoned 'villages' separated by sky courts, and on the main level, a sky bridge to the neighboring tower. Floor plates are optimized for natural light and ventilation, staggered and adjusted for each use. Each plate rotates 5 degrees to create a twisting tower. An atrium follows the twist a full 250 degrees, in an east to west path allowing direct sunlight for each hour of the day. The circular core is the only straight vertical element, carrying primary circulation and services. Two additional helical elevators follow the twist of the atrium, using maglev technology. An exoskeleton diagrid lattice works in equilibrium with the circular core and floor plates to provide the structure. The tapering helical form is ideally suited to resist resonant wind effects, and is completed by a massive vertical axis wind generating turbine on the crown.
