Two ZHA projects included in Emporis' Skyscraper Award top ten of 2019

One Thousand Museum in Miami and Leeza SOHO in Beijing are both included in the Emporis' Skyscraper Award top ten of 2019.

Chosen by an international jury of experts from over 700 skyscrapers worldwide completed in 2019 with a minimum height of 100 meters, the Skyscraper Award by Emporis, a global provider of building data, is the world’s most renowned prize for high-rise architecture.

One Thousand Museum’s 62-storey concrete exoskeleton - a web of flowing lines integrating structural support with lateral bracing – reads from top to bottom as one continuous frame. Columns at its base fan out as the tower rises to meet at the corners, forming a rigid tube highly resistant to Miami’s demanding wind loads; its curved supports creating hurricane resistant diagonal bracketing. “The design expresses a fluidity that is both structural and architectural,” explains project director Chris Lepine. “The structure gets thicker and thinner as required, bringing a continuity between the architecture and engineering.” The design incorporates GFRC form-work which remains in place as construction progresses up the tower. This permanent concrete form-work also provides the architectural finish that requires minimal maintenance. Behind the exoskeleton, the faceted, crystal-like façade contrasts with the solidity of the structure. With its frame at the perimeter, the tower’s interior floor plates are almost column free; the exoskeleton’s curvature creating slightly different plans on each floor. On the lower floors, terraces cantilever from the corners, while on the upper floors, the terraces are incorporated behind the structure.

Leeza SOHO is adjacent to the new rail station at the intersection of five new lines currently under construction on Beijing’s Subway network, with its site 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. The space between these two halves extends the full height of the tower, creating the world’s tallest atrium at 194m which rotates 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’, creating a fantastic new civic space for Beijing that is directly connected to the city’s transport network. 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; creating extremely efficient environmental control for each floor. With LEED Gold certification, Leeza SOHO’s energy management system monitors real-time environmental control and energy efficiency. The tower includes an insulating green roof with photovoltaic array; 2,680 bicycle parking spaces, with lockers, showers and charging spaces.

One Thousand Museum and Leeza SOHO continues Zaha Hadid Architects’ commitment to the highest standards of high-rise design and construction, with Wangjing SOHO in Beijing (2014) and Generali Tower in Milan (2017) honoured in previous cycles of the Skyscraper Award.
