The tower itself is 126,000 square feet that will be divided up between retail, office, hotel and residential spaces. The building is a long tower which is anchored to the ground by a 38 meter diameter spiral. This feature will enclose an indoor plaza or ‘winter garden’ connecting the two sides. The spiral provides major support for the structure and encapsulates the five public venues near the ground level. In between these five spaces, four courtyards let natural let in and are each shaped to represent the four seasons of the year.
