Au – This expo is a retail facility adjacent to 2025 (Osaka, Cancei) Arena. Since the expo site was constructed on the coastal renovated land, it was proposed that an architectural structure be made up by raising sea plastic waste. Marine plastic pollution severely affects the ecosystem worldwide and is recognized as a shared global issue. The purpose of this architectural project is to promote the concept of a circular economy at the expo site, where visitors from all over the world will gather. The building, including its foundation, is designed for easy assembly and is disabled with a plan of transfer or reuse as furniture after the end of the expo.
