Common places are designed with regard to the needs of people. This is usually associated with the physical-material dimension of space, i.e. the natural and built environment. However, the social and individual dimension must also be included in the design of space. So common places are not only designed for people, but also with them. But how exactly do people relate to it? Why and which spaces are important for people? Neighbourhoods in housing estates for example start from a place and require a spatial-built structure that connects people living close to each other; a formation of buildings and facilities through which neighbours can make contact with each other or keep their distance. From a spatial sociological perspective, housing estates as physical superstructures do not simply exist as rigid, unchanging complexes, but have always been created in a certain temporal context under certain conditions and are subject to constant change through use. The neighbourly determination of belonging depends on the spatial density and proximity of the development. The circle of known neighbours in high-rise buildings is thus generally defined more narrowly, whereby the integration of various facilities made available to the residents for common use is decisive. Young people attribute particular importance to outdoor common places with installed playground equipment, sports fields and open spaces for their socialisation.
