UK-based Chetwood Architects just unveiled plans for the Phoenix Towers in Wuhan, China, which will be the world’s tallest pair of skyscrapers upon completion. The supertall structures are the centerpiece of the firm’s four master plans slated for construction in China. The Phoenix Towers are outfitted with wind turbines, solar panels, thermal chimneys and rainwater harvesting systems and they will act as an “environmental catalyst” to re-invigorate the city of Wuhan. Inspired by the symbol of the Chinese Phoenix, which combines male and female principles in perfect balance, the architects designed two interdependent towers. The “male” one (Feng) feeds the “female” (Huang) with renewable energy and together they act as a beacon of sustainability in the area.
