Design: relating to an overall design, legibility, place
management and building design;
Ownership: relating to clear definition, borders and
appropriate streetscapes, good location signage is an
important tool that enables emergency services to respond
promptly and timely to a routine call for assistance;
Individuality: social and cultural context, and no one size
fits all;
Management: activity mix and generation, maintenance
and response to provide safe recreational spaces;
Additional Requirements for Particular Types of
Development: additional requirements for residential and
public areas.

not only crime prevention, but has also
different goals:
1.To create an aesthetically pleasing physical
evironment for everybody
2.Promote both positive and desired
behaviours
3.Support the productive use of space
Natural Access Control takes advantages of
various elements in the design, for example,
•entrances and exits
•sidewalks and paths
•landscaping
•lighting
•signs
and uses these to direct and control movement
and to define appropriate behaviours
Natural Surveillance refers to areas where
people and their activities can be readily
observed
•Therefore the site and building design must
ensure that users can see and be seen
•Proper selection and placement of
landscaping, lighting and windows can create
opportunities for natural surveillance
Territorial Reinforcement refers to the
development of areas or places where
the users feel a strong sense of
ownership.
It is an umbrella concept, embodying all
natural surveillance and access control
principles
• Design for everybody for
every day use
• No matter what user group (age,
ethnic or social background,
education, religion, race)
• New Urbanism
(increasing use of public
space)
• Communication, mobility,
technology, climate, public viewing
• Accessibility
• Fluctuation and overall time flow
• Target user groups
• Dedicated to special user groups
• Private engagement
• Informal social control rather than
formal
• Widening the radius from people of
social low-key areas
• Unlimited radius
