Defensible Space Theory is a concept developed by architect Oscar Newman in the 1970s. It focuses on designing urban environments to reduce crime and enhance safety. The theory emphasizes the importance of physical design elements, such as natural surveillance, territorial reinforcement, and access control, to create spaces that discourage criminal activity. The idea is that well-designed spaces can empower residents to take ownership of their environment. By fostering a sense of community and encouraging social interaction, Defensible Space Theory aims to create areas where people feel safe and are more likely to look out for one another, ultimately reducing crime rates.
