The London-based practice was selected to provide a 150,000m2 'eco-quarter' in the downtown region of Singapore.
The scheme will incorporate commercial, residential, retail and two high-end hotels, as well as a new 'green' transport link to the city's Mass Rapid Transit train station.
Central to the project is a canopy comprising articulated ribbon forms that flex above the public spaces and continue up the east and west elevations of the towers, helping to filter the sun.
The practice claims: 'The buildings' forms and slanted facades are oriented to catch prevailing winds and direct air flow downwards to cool the ground level spaces.'
It is hoped the project will also provide a new civic destination for Singapore.
