UNStudio's competition design for the new Yongjia World Trade Centre in Wenzhou presents a green neighbourhood in the sky which combines three main aspects of trade and business, a diverse program mix and an accessible public landscape. The notion of precious objects on a tray drives the main design concept, where the continuous podium landscape occupies the entire site and serves as a tray-like, green plain for the towers. The composition of the towers will interweave with its surroundings, yet will remain recognisable as a family of objects.
