Territory can provide a sense of security from the danger that is happening out there. Territory is one of the variables in Crime prevention through environmental design concept, yet the concept of territory as a crime prevention in the interior is less concerned. Therefore, this research will explain and expose the territory concept as crime prevention method in interior design in public space where people expect to see strangers in this space. For the result, territory concept can be achieved as a crime prevention in interior design, with mechanisms that should be applied in each type: the boundary between areas; limitation to the symbolic; supervision and control of space.
