The infrastructure space is the node of moving path. It functions to connect different places and keep people moving tot her their destination. Within the density of the city, the infrastructure is unavoidably packed of people. The individual can't stop on the way, he is like an object been moved from one place to another. In the night, the infrustructure space that was packed with people and objects becomes empty. The familiar space is strangely large and border-less almost like a natural scene. The infrastructure space now is the place to stay. The night worker can stay in the space undisturbed. He is alone in the space experiencing the dramatic emptiness.
The design introduces the neutral space to daytime as an extension of the infrastructure. Contrasting to the noisy and busy infrastructure space, this created space reproduced the quality of then night space which has no distinated program but allow people to experience this large volume by themselves.
