What the evidence says
Secured by Design (SBD) is a UK police initiative aimed at reducing crime through enhanced building security. Established in 1989, it promotes specific security standards for property development, which have shown a significant reduction in burglary rates. Evidence suggests that properties adhering to these standards experienced a 53% lower burglary rate and a 77% lower attempted burglary rate when compared to non-compliant properties.
How it works
SBD reduces crime by enhancing household security, making opportunities for burglary less accessible and deterring would-be offenders through various physical security measures. Improved lighting and robust building designs serve to increase the chances of detection, thereby deterring criminal activities.
Implementation
The review did not provide specific information on how SBD is implemented or any related challenges, highlighting a gap in understanding the practical execution of these standards.
