South Somerset District Council is proud to work closely with Avon and Somerset Constabulary to reduce crime and develop safer communities.

The Constabulary has a specialist team of Designing Out Crime Officers (DOCOs) who work with architects, developers and local authority planners to incorporate crime prevention measures into new residential developments and refurbishments.

Trained by Secured by Design (SBD), the national police crime prevention initiative, DOCOs offer advice on the physical security of buildings, such as doors, windows and locks, to make sure they are sufficiently robust to withstand attack from opportunistic criminals. In addition, they give guidance on the layout and landscaping of developments. This includes working to maximise natural surveillance and limit through movement. Combining all of these measures and techniques have been proven to reduce crime by up to 87% each and every year in the lifetime of a development.

The work of SBD is embedded in the planning process. It is referenced in the National Planning Policy Framework (which sets out the Government’s planning policies for England and how these should be applied) and the National Planning Practice Guidance (which brings together planning guidance on various topics into one place).

SBD has produced a series of Design Guides to assist local authorities and the construction industry on how they can incorporate security into developments in order to comply with the Building Regulations in England and meet the requirements of SBD. These guides are updated regularly to keep pace with changing patterns of criminal behaviour.

Today, one million new homes have been built to SBD crime prevention standards around the UK.
