What does 'defensible space' promote in a built environment?

Defensible space promotes the idea of reducing crime opportunities within a built environment. This concept was developed by architect Oscar Newman in the 1970s, emphasizing how the design of urban spaces and residential areas can influence the behavior of residents and potential offenders. By creating environments that allow for natural surveillance and territoriality—such as well-defined public, semi-public, and private spaces—defensible space helps occupants feel a sense of ownership and responsibility over their surroundings. This increased awareness and attentiveness can deter criminal activities, as the presence of vigilant residents makes it less likely for crimes to occur unobserved.

While there are merits to the other options, they are not the primary focus of the defensible space concept. For instance, promoting psychological security, creating personal territories, and encouraging social interactions all relate to the broader context of urban design and community building, but the primary intent of defensible space is specifically about curtailing opportunities for crime through thoughtful environmental design.
