The 45-storey tower also boasts the world's largest atrium, located in 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.

This 45-storey 172,800 sq m 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.

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 194.15 metres.

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 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.

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.
