The Yongjia World Trade Centre, located in the new riverside city of Wenzhou, presents a functional shift of the WTC area from a business and financial district to a mixed-use development incorporating cultural and recreational facilities and a high percentage of residential properties. The notion of precious objects on a tray drives the main design concept by UNStudio, where the continuous podium landscape occupies the entire site and serves as a tray-like, green plain for the towers. On the tower scale ‘frames’ underline the concept of neighbourhoods in the sky which create unique locations with distinct identities. Where these frames overlap the so-called ‘Eyes’ are located. These are communally used spaces such as sky gardens and lounges, or social gathering places for office areas that afford the best views towards the river and city centre.
