'Flexi-port' is not only about urban planning. It is the integration of city planning, mega structure, functional space and the representation of the sea surface. Its responsive structure can reconfigure to accommodate infinite activities and more importantly to interact with the people occupying the space as it synchronizes with the life of the sea. As it is a generic responsive structural system, which adapts to different spatial condition, it can enliven and enrich the waterfront, at the same time bring its smooth, dynamic surface into the striated city. Moreover, the system demonstrates architecture as a tool to experiment different programs. It is believed that different from ordinary constructions, the making-up process of the responsive system will sure become a part of an event in the future. People will no longer think how much land they can ‘create’ in the harbor, but how to make use of the existing valuable resources we already have.
