Secured by Design

Secured by Design is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Secured by Design rather than just read about it. In short: Secured by Design (SBD) is a police initiative in the UK that advises on the construction of buildings and development schemes to encourage the adoption of techniques or designs that are thought to discourage crime. SBD recommendations are included in the National Model Design Code and the programme incorporates training police officers as Designing Out Crime Officers (DOCOs), who are referred to in the National Pla…

Key takeaways

  • Secured by Design belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Secured by Design to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Secured by Design from memory before moving on to harder problems.

Reference excerpt

Secured by Design (SBD) is a police initiative in the UK that advises on the construction of buildings and development schemes to encourage the adoption of techniques or designs that are thought to discourage crime. SBD recommendations are included in the National Model Design Code and the programme incorporates training police officers as Designing Out Crime Officers (DOCOs), who are referred to in the National Planning Policy Framework, giving the initiative wide influence over British construction.

History Secured by Design was created in 1989 as a response to perceived failings of the estates built in the UK's postwar era, with two focuses: the vulnerability of certain construction methods, such as doors or glazing that were considered easy for burglars to bypass; and the wider design of housing estates or urban areas, which often incorporated pedestrian routes that were thought to create escape routes for criminals. Secured by Design developed into a wide set of standards and design approaches, including on road and footpath layouts, lighting, street furniture, public or communal spaces (such as parks and playgrounds), fencing, planting, building positioning, and the materials used in construction. Urbanist Adam Greenfield says that Secured by Design is based on the principles of Defensible Space, developed in the 1970s by architect Oscar Newman. The scheme is administered by Police Crime Prevention Initiatives, a limited company set up by the ACPO. After the ACPO's dissolution, ownership was transferred to the London Mayor's Office for Policing and Crime. The Director of ACPO Secured by Design in 2012 described the goals of the scheme as "reducing crime and the fear of crime through a blend of design and realistic physical security", claiming that "independent research shows that SBD properties suffer 50% less burglary" with other benefits across other forms of crime and the fear of crime.

Criticism Some urbanists and planners have criticised the power the police have over construction and public spaces. Urbanist Phineas Harper described the impact of the scheme as "rooted in systemic prejudices rather than community-centred design principles" and noted Secured by Design's promotion of cul-de-sacs, which have been increasingly criticised by urban planners for encouraging sprawl and unsustainable living. Architect Russell Curtis criticised the scheme's standards as "diametrically opposed to good placemaking", citing examples of his practice where Designing Out Crime Officers had called for public areas to be gated off and arguing that they had too much influence over local authority planners. Echoing these criticisms, Gloucester City Council decarbonisation lead Jon Burke argued that SBD's recommendation to remove trees and greenery may also harm communities and increase overall crime, citing studies by the Yale School of Public Health that found increasing urban tree canopy cover decreased violent and property crime. Secured by Design has also been criticised for the removal of street furniture and planting, including a flower walkway in Southwark that was said to be blocking CCTV sight lines, benches and shrubs in parks in Ashford, and foot and bike paths in Horsham. However, the UK police have defended Secured by Design's principles. Responding to Harper's criticisms, Matthew Scott, the Police and Crime Commissioner for Kent, claimed local residents in Ashford supported action to reduce anti-social behaviour. Jon Cole, the COO of Police Crime Prevention Initiatives argued that criticisms are based on misconceptions of the scheme, that cul-de-sacs are self-policing, and that overall "there is sometimes a little bit of inconvenience, but one which buys enormous amounts of safety."

Worked examples

Example 1 — a first encounter with Secured by Design

Start with the simplest possible case. Write down what Secured by Design claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Secured by Design before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Secured by Design ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Secured by Design

In research
Secured by Design appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Secured by Design in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Secured by Design is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crime prevention, Criminology, Environmental psychology, so understanding it makes those chapters shorter.
In everyday life
Look for Secured by Design outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Secured by Design matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Secured by Design?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
