Abstract: Hankou Quanye tower, being a mutiple- function high- rise building, has a close relationship with its?environment, its design is not only a process of composing the inner space and outer space but also a process of?differentiation which imposes the environmental restrictions on its inner space.With a special conception, it offers a veryelastic inner space and creates a very characteristic outer image at the same time, thus giving an excellent space for urban?cultural life.
