Defensible Space is a concept in urban design aimed at reducing crime by creating environments that promote natural surveillance and territoriality. Developed by architect Oscar Newman in the 1970s, it emphasizes the importance of physical design elements, such as lighting, landscaping, and building layout, to foster a sense of ownership and community among residents. By encouraging residents to take responsibility for their surroundings, Defensible Space helps deter criminal activity. Features like clear sightlines, well-defined boundaries, and active public spaces can enhance safety, making it more difficult for potential offenders to operate unnoticed in neighborhoods.
