RESEARCH ON NATURAL SURVEILLANCE AND ACCESS CONTROL OF WINDOWS DAMAGED BY BURGLARS IN LOW-RISE APARTMENT HOUSES

Abstract

This research observed built environment of low-rise apartment houses attacked by burglars by field survey. On the ground floor, the burglary risk of apartments of which balconies face the back and the side was more than three times higher than that of the front. Approximately 70 percent of the damaged windows were not naturally visible from the streets mainly obstructed by fences and partitions for protecting privacy. Moreover, approximately 90 percent of the attacked apartment houses which balconies face the side do not have enough access control for some possible intrude routes, even where directly reach the side.
