Hangzhou Wulin Star Expo Center is located in the core area of Hangzhou city center and belongs to the historical protected buildings in the original Hangzhou Oxygen Plant building complex. The protection and utilization strategy of this project is to allow history and the future to intersect here, making the space itself a medium for storytelling. Design should not only preserve the original elements to the greatest extent possible, but also allow for the coexistence of old and new elements.
