Nowadays, the singularity of outdoor space in urban community has been unable to meet the needs of people. The concept of home, the smallest unit of society, is changing with the change of family structure. The huge living community consists of a family of loose relationship or fragmented families, each of which is an island. In the past, it is said that a neighbor that is near is better than a brother far off. However, at present, a close neighbor is like a stranger. The walls of the building have become a barrier for people to communicate. People’s activities should not be restricted by the ”box” of home. Can we open the walls and re-design the outdoor space? Therefore, we begin to think about the connection between people, can we achieve it through space? Can there be more public space between neighborhoods? Can such a public space be used as part of the family space again? In this paper, the outdoor space of urban community is taken as the research object to strive to break the boundaries of traditional indoor and outdoor space. How to optimize the outdoor public space in urban communities to promote residents’ communication is taken as the purpose of research to carry out a new design of this kind of space. The outdoor space outside the traditional wall is combined with the living needs of present people to discuss the possibility shaping of outdoor space in urban community.
