In February 2021, China began to prepare for the 14th meeting of the Conference of the Parties to the Ramsar Convention on Wetlands. The venue of the conference was located in Wuhan, a city with many lakes. Therefore, the important supporting building of the conference, the Exhibition Hall for the Achievements of the 30th Anniversary of Chi-na's Implementation of the Ramsar Convention on Wetlands, was located in East Lake of Wuhan. We hope to revitalize and regenerate the old factory through the design, and implant new cultural scenes and display functions while retaining the memory of the place. By referring to the shape of waterfowl wings and combining with the lift and fold curves of traditional Chinese wooden buildings, we designed a shed roof with deep eaves, and set a mezzanine in the higher side of slope facing the large lake to form a viewing platform. Following the “explore structure directly tradition”of ancient Chi-nese architecture，we deliberately exposed the entire structure to reveal the expressive wooden structure system under the eaves.
