It integrates the comprehensive cultural activity center, the comprehensive community service center, the origin and the terminal stations. We put forward the design concepts: One Box-Scarcity of Public Space; One Corridor-Three-Dimensional Public Space; One Shadow-Permeability of Public Space; One Forest-Recognition of Public Space. The narrow ground public space is not enough to satisfy the needs of all kinds of people, so we tack the origin and the terminal stations, the community comprehensive service center and the cultural activity center vertically in a box of no more than 24 sqm.
