Immigrants account for nearly half of Shanghai's population at present, and their background are as tanglesome as Shanghai itself. Many of them flow in the city in a placeless life. On the one hand, immigrants now become an inalienable element when we discuss Shanghai. On the other hand, old Shanghai city has many old structures such as lilong houses survived from previous developments. This project is trying to explore the opportunities of a new mobile lifestyle of Shanghai immigrants by exploring a new architecture responses in relation to those existing structure.
