Crime is a social problem in our society that affects thousands of people’s lives each year.
“Crime Prevention Through Environmental Design (CPTED) is a multi-disciplinary approach of crime prevention that uses urban and architectural design and the management of built and natural environments. CPTED strategies aim to reduce victimisation, deter offender decisions that precede criminal acts, and build a sense of community among inhabitants so they can gain territorial control of areas, reduce crime, and minimise fear of crime.”

By incorporating CPTED theory at the outset of a project, a reduction in other security measures (sometimes very costly ones) can be realised. Landscaping is an element of CPTED and has many benefits when utilised, detection, deterrence and delay of intruders.
CPTED has 3 underlying elements; mechanical, organisational and natural. The following are CPTED tools which should be integrated into landscape design:
- Natural Surveillance – Design the outdoor space to allow visibility by legitimate users and keep unwanted behaviours under observation.
- Territorial Reinforcement – Using design elements such as pavements, hardscape, soft landscaping, and low fencing or barriers such as hedging to help distinguish between public and private areas. Foster a sense of ownership.
- Natural Access Control – Use landscape elements such as strategic entrances and fences to deny admission, limit access and create a perception that there is a risk in targeting an area.
- Maintenance – Regular cleaning, repairing and landscape maintenance lets people know that an area is cared for and will be defended against vandalism or intruders.
