Also on a small scale — particularly in connection with individual dwellings — clarifying territories and affiliations is crucial for contact with others and for protecting the private sphere. Whereas efforts are made to graduate and soften transitions between private and public areas by building semiprivate and semipublic transition zones, the likelihood of contact from zone to zone increases, and residents gain the opportunity to regulate contacts and protect private life. A well-proportioned transition zone can keep events at a comfortable arm’s length. In the previous section soft edges and their importance for life in the city are discussed. It is emphasized that edge zones, porches and front yards can make a decisive contribution to vitalizing life in public space. These transition zones between the private and public sphere must be carefully articulated in order to clearly distinguish between what is private and what is public. Changes in pavement, landscaping, furniture, hedges, gates and canopies can mark where public space ends and fully or semiprivate transition zones begin. Height differences, steps and staircases can also mark the transition zone, providing critical prerequisite for the important function of soft edges as the link between inside and out, between private and public. Only when territories are clearly marked can the private sphere afford the degree of protection that people need to make contact with others and contribute to life in the city.
