The swirling volumes were inspired by the helix DNA structure and the Taij philosophy based on dynamism and harmony. The towers are covered with greenery cascading down and boasting 360-degree panoramic views of the city. They are a combination of trees and buildings, whose energy-efficient performance is complimented with hyper-flexible, column-free spaces formed thanks to a structural system based on the Vierendeel Truss.
The architect developed 24 prototypes of Citytrees based on the technical innovations of the Tao-Zhu-Yin-Yuan project in Taipei, Taiwan, currently under construction. They were conceived as proposals for different urban contexts that raise awareness of green sustainable architecture. Drawing on passivhaus principles and sustainable technology, the structures are meant to produce more energy that they consume and transform cities into vertical, dense, interconnected eco-systems.
