Prof. Guohua Fu, the founder and Chief Designer of KFS International Architect Firm, started the program of Ecological Box Theatre with Shanghai Cultural Square. Ecological Box Theatre is the first outdoor theatre in Shanghai. The Ecological Box theatre recycle and reuse used containers as building materials. This project turn useless containers as innovative and interesting theatre space. Pardon, pluralism, openness, and share are most important design concepts for Prof. Fu. The most significant characteristics for the outdoor theatre is the aggregative multidimensional stage. The whole theatre is made by a container used as the main stage surrounding by other small containers. Within this particular stage, there are dressing room, performance stage, entrance, assess route, auditorium, toilet and evacuation exit. For the auditorium, chairs that can be rotated in 360 degree provides a brilliant view to audience. The form of semi-enclosed stage shortens the distance between audience and actors. In addition, it transfers the theater into an ecological environment. Moreover, the whole working process did not produce any construction waste and rubbish.
