Project Zaha Hadid Architects Leeza SOHO Location Beijing, China Date 2015/2018 Client SOHO China Ltd. 01 Status Under Construction Site Area 30,688m² Gross Floor Area 172,800m² 01 Leeza Soho Construction of Leeza Soho, a 46-storey (207m) mixed-use tower with the world’s tallest atrium, has reached level 20. Within the Lize Financial Business District - a new business, residential and transport hub adjacent to Financial Road in southwest Beijing - Leeza Soho is located at the intersection of Lines 14 and 16 currently under-construction for the Beijing Subway rail network. Directly above the new interchange station, Leeza Soho connects with the city’s bus network on Lize Road to the north and Lou Tuo Wan East Road to the east. Anchoring the financial district, the 172,800m² Leeza Soho design has evolved from its specific site conditions. Straddling the new subway tunnel that diagonally divides the site, the tower rises as a single volume divided into two halves on either side of the tunnel. A central atrium - the world’s tallest - extends 190m through full height of the building, connecting the two halves together. As the tower rises, the diagonal axis through the site defined by the subway tunnel is re-aligned by ‘twisting’ the atrium through 45 degrees to orientate the atrium’s higher floors with the east-west axis of Lize Road, one of west Beijing’s primary avenues. Connecting with the interchange station below, this 190m atrium will be a new public space for the city. An outdoor, public piazza surrounds the tower, echoing its circular form at the centre of the new financial district and welcoming visitors inside. The atrium’s ‘twist’ allows natural light and views of the city from the centre of all floors 02 01-02 Renders by MIR Zaha Hadid Architects Architect Competition Project Consultants Executive Architect Size Floors Below Ground Zaha Hadid Architects Directors BIAD 4 levels: Structure Site Area Satoshi Ohashi 2 levels retail Design Bollinger + Grohmann General Contractor 30,688 m2 Manuela Gatto 2 levels parking Zaha Hadid (Competition) China State Construction Gross Floor Area subway tunnel Patrik Schumacher Competition Team CABR (SD) Engineering Corporation 172,800 m2 Lead Designers BIAD (DD) (CD) #3 Retail Project Director Philipp Ostermaier Above Ground 10,000 m2 Satoshi Ohashi Facade Facade Contractor Dennis Brezina 124,000 m2 KWP (SD) Lingyun Vehicle Parking Project Associate Claudia Glas Dorner Kighton Façade Yuanda Towers & Pavilions 480 Kaloyan Erevinov Competition Team Yuanda (DD) (CD) Tower: 123,740 m2 Ed Gaskin Bicycle Parking Yang Jingwen Pavilions: 220 m2 Armando Solano MEP 2,680 Igor Pantic Parsons Brinkerhoff (SD) Below Ground Project Architect Mu Ren BIAD (DD) (CD) 48,800 m2 Philipp Ostermaier Konstantinos Mouratidis Nicholette Chan Lighting Height Project Team Yung-Chieh Huang Light Design (SD) (DD) 207 m Yang Jingwen Leuchte (CD) Di Ding Top of occupied floor Xuexin Duan Landscape 190.5 m (45 floors) Samson Lee ZHA (SD) (DD) Floors Above Ground Shu Hashimoto Ecoland (DD) (CD) 46 levels: Christoph Klemmt Interiors Lobby 3,900 m2 Juan Liu ZHA (SD) (DD) Offices 110,474 2m Dennis Brezina Huateng (CD) MEP floors 9,406 m2 Rita Lee Seungho Yeo Leeza Soho of Leeza Soho.

Zhang Xin, CEO of Soho China explained: At the forefront of 3D Building Information “China attracts the best talent from Modelling (BIM) in design, construction around the world. It’s important to work management and building operations, with architects who understand what Zaha Hadid Architects and Soho China the next generation requires; connecting have implemented proven technologies to communities and traditions with new significantly reduce the energy consumption technologies and innovations to embrace and emissions of their previous project the future.” collaborations. Targeting LEED Gold certification, an advanced 3D BIM energy management system will monitor real-time environmental control and energy efficiency within Leeza Soho, integrating heat-recovery from exhaust air, high-efficiency pumps and fans, chillers and boilers, lighting and controls, in addition to water-collection, low-flow rate fixtures, grey water flushing and landscape irrigation. 04 03-04 Renders by MIR.
