‘Leeza SOHO’ is the most recent of four project collaborations between Zaha Hadid Architects and SOHO China, totaling 1.4 million square meters of office and retail space. Anchoring the new financial district in the heart of Beijing, the tower is currently under construction where it is scheduled to reach its full 207 meter-height in September, and be completed by late 2018.
The proposal by Zaha Hadid Architects straddles a new subway tunnel that diagonally divides the site. A distinctive feature is the building’s central atrium — the world’s tallest — that extends 190 meters through the full height of the structure. This architectural feature, which will be a new public space for the city, allows natural light and views of the city to reach all floors.
Structurally, the envelope uses a double-insulated, unitized glass curtain. This wall system steps the glazing units on each floor at an angle, allowing ventilating registers to draw outside air through an operable cavity when required, creating efficient environmental control for each floor. The scheme hopes to reach LEED gold certification using techniques, including the self-shading atrium that will be insulated with low-e glazing to promote a comfortable indoor environment throughout Beijing’s changing seasons.
