At the request of OUTLOOK magazine, three different concepts are conceived to imagine how to deal with the 2010 shanghai world expo pavilions. By stacking them, by floating them, or by building over them, these expo pavilions will be saved without judgment on their values, beauty or nationality. While they will serve the different purpose and functions in the future, the symbols of this phenomenal extravaganza will be transformed and integrated into people’s life, and ultimately the city. Better city better life. Be thrifty, no waste.
