This project is a warehouse, storing materials for flood control on Dongtaihu Lake border, Suzhou, China. The main job to the architects was to get the boundaries between nature, architecture and time, to avoid the changing of the original lakeside landscape and ecology by building the warehouse. The solution is " Natural wisdom " which made the warehouse "growing" with the lakeside environment, by time. Design techniques were:1. Location: maximum concealment.2. Construction: buried, above the flood level line.3. Growth: time made hiding more natural. What it delivers is something appropriate and sustainable.
