Leeza SOHO tower designed by Zaha Hadid Architects, one of them more anticipated skyscraper in Beijing, opened to the public yesterday.
The tower already made a big attention in architectural media during its construction with its 190-meter-tall (623-foot), full-height atrium (the world's tallest) and spectacular, Piranesiesque construction photographs of the structural skeleton.

Located on Lize Road in southwest Beijing, Leeza SOHO tower, The 45-story development, anchors the new Fengtai business district – a growing financial and transport hub between the city centre and the recently opened Beijing Daxing International Airport to the south.
Project description by Zaha Hadid Architects
Located on Lize Road in southwest Beijing, Leeza SOHO tower anchors the new Fengtai business district – a growing financial and transport hub between the city centre and the recently opened Beijing Daxing International Airport to the south. The new business district is integral to Beijing’s multi-modal urban plan to accommodate growth without impacting existing infrastructure networks in the centre of the city.
This 45-storey 172,800m² tower responds to demand from small and medium-sized businesses in Beijing for flexible and efficient Grade A office space.
Adjacent to the business district’s rail station at the intersection of five new lines currently under construction on Beijing’s Subway network, Leeza SOHO’s site is diagonally dissected by an underground subway service tunnel.
Straddling this tunnel, the tower’s design divides its volume into two halves enclosed by a single facade shell. The emerging space between these two halves extends the full height of the tower, creating the world’s tallest atrium at 194.15m which rotates through the building as the tower rises to realign the upper floors with Lize road to the north.
This rotation of the atrium intertwines Leeza SOHO’s two halves in a dynamic ‘pas de deux’ with connecting skybridges on levels 13, 24, 35 and 45; its glaced facade giving panoramic views across the city.
Leeza SOHO’s atrium acts as a public square for the new business district, linking all spaces within the tower and providing varying views due to its twisting, sculptural form; creating a fantastic new civic space for Beijing that is directly connected to the city’s transport network.
The atrium brings natural light deep within the building, acting as a thermal chimney with an integrated ventilation system that maintains positive pressure at low level to limit air ingress and provides an effective clean air filtration process within the tower’s internal environment.
Leeza SOHO’s double-insulated, unitised glass curtain wall system steps the glazing units on each floor at an angle, providing narrow ventilating registers to draw outside air through operable cavities where required; creating extremely efficient environmental control for each floor.
The two halves of the tower shade the atrium’s public spaces, while the double-insulated low-e glazing maintains a comfortable indoor environment in Beijing’s extreme weather conditions. With a u-value of 2.0 W/m²K, the glazing has a shading coefficient of 0.4. The tower’s overall external envelope u-value is 0.55 W/m²K.
At the forefront of 3D Building Information Modelling (BIM) in design, construction management and building operations, Zaha Hadid Architects and SOHO China have implemented proven technologies to reduce the energy consumption and emissions at each of their four collaborations, totalling 15 million square feet (1.4 million sq. m) of mixed-use urban space in Beijing and Shanghai.
Designed to achieve LEED Gold certification by the US Green Building Council, Leeza SOHO’s advanced 3D BIM energy management system monitors real-time environmental control and energy efficiency. These systems also include heat recovery from exhaust air and high-efficiency pumps, fans, chillers boilers, lighting and controls. The tower incorporates water-collection, low-flow rate fixtures and grey water flushing as well as an insulating green roof with photovoltaic array to harvest solar energy.
2,680 bicycle parking spaces, with lockers, shower facilities and dedicated charging spaces for electric and hybrid cars are located below ground; while low volatile organic compound materials are installed throughout Leeza SOHO to minimise interior pollutants and high efficiency filters remove particulates via the air-handling system.

ZAHA HADID
Zaha Hadid, (Bagdad, 31 October 1950 – Miami, 31 March 2016) founder of Zaha Hadid Architects, was awarded the Pritzker Architecture Prize (considered to be the Nobel Prize of architecture) in 2004 and is internationally known for both her theoretical and academic work.
Each of her dynamic and innovative projects builds on over thirty years of revolutionary exploration and research in the interrelated fields of urbanism, architecture and design. Hadid’s interest lies in the rigorous interface between architecture, landscape and geology as her practice integrates natural topography and human-made systems, leading to experimentation with cutting-edge technologies. Such a process often results in unexpected and dynamic architectural forms.
Education: Hadid studied architecture at the Architectural Association from 1972 and was awarded the Diploma Prize in 1977.
Teaching: She became a partner of the Office for Metropolitan Architecture, taught at the AA with OMA collaborators Rem Koolhaas and Elia Zenghelis, and later led her own studio at the AA until 1987. Since then she has held the Kenzo Tange Chair at the Graduate School of Design, Harvard University; the Sullivan Chair at the University of Illinois, School of Architecture, Chicago; guest professorships at the Hochschule für Bildende Künste in Hamburg; the Knolton School of Architecture, Ohio and the Masters Studio at Columbia University, New York. In addition, she was made Honorary Member of the American Academy of Arts and Letters, Fellow of the American Institute of Architecture and Commander of the British Empire, 2002. She is currently Professor at the University of Applied Arts in Vienna, Austria and was the Eero Saarinen Visiting Professor of Architectural Design at Yale University, New Haven, Connecticut.
Awards: Zaha Hadid’s work of the past 30 years was the subject of critically-acclaimed retrospective exhibitions at New York’s Solomon R. Guggenheim Museum in 2006, London’s Design Museum in 2007 and the Palazzo della Ragione, Padua, Italy in 2009. Her recently completed projects include the MAXXI Museum in Rome; which won the Stirling award in 2010. Hadid’s outstanding contribution to the architectural profession continues to be acknowledged by the most world’s most respected institutions. She received the prestigious ‘Praemium Imperiale’ from the Japan Art Association in 2009, and in 2010, the Stirling Prize – one of architecture’s highest accolades – from the Royal Institute of British Architects. Other recent awards include UNESCO naming Hadid as an ‘Artist for Peace’ at a ceremony in their Paris headquarters last year. Also in 2010, the Republic of France named Hadid as ‘Commandeur de l’Ordre des Arts et des Lettres’ in recognition of her services to architecture, and TIME magazine included her in their 2010 list of the ‘100 Most Influential People in the World’. This year’s ‘Time 100’ is divided into four categories: Leaders, Thinkers, Artists and Heroes – with Hadid ranking top of the Thinkers category.
