Crime Prevention Through Environmental Design (CPTED) is a set of design principles used to discourage crime. The concept is simple: Buildings and properties are designed to prevent damage from the force of the elements and natural disasters; they should also be designed to prevent crime. Here are 5 ways that you can use these principles to improve anything from a home office to a high-rise buildings.
CPTED is not meant to be a cure-all for criminal behavior, nor should it be the only weapon in your crime prevention arsenal. It is, however one effective, and often inexpensive, method of securing your building and property.
2. Use Natural Surveillance to keep a watchful eye out.
Criminals thrive on anonymity. They do not like to be seen or recognized, so they will normally choose situations where they can hide and easily escape. Natural surveillance, then, is simply arranging your property for maximum visibility.
3. Control the flow of traffic with Natural Access Control.
Criminals like to feel that they are in control as they enter and exit an area. When they are in control, they have a low perception of risk, since they believe they are able to move about unnoticed. However, this sense of control can be denied by limiting and clearly marking the approaches to buildings and properties, thereby channeling visitors into a defined area.
4. Stake your claim with Territorial Reinforcement.
The purpose of territorial reinforcement is to create a clear distinction between public and private property. This is important for two reasons: legitimate occupants have a sense of ownership and will notice people who don't belong; intruders, on the other hand, will have a hard time blending in.
5. Apply the Broken Window Theory with regular Maintenance.
Surprising as it may seem, many experts believe that a well maintained property can deter crime. Why? Because a poorly maintained building demonstrates that its owner is no longer able or willing to control his property. It thus becomes an invitation to any criminal who wants to seize control. To state it positively, a well-maintained property demonstrates vigilance, watchfulness and involvement. These are the very things that intimidate the potential offender.
