Some urban planners have argued that redesigning stores and residential buildings in cities can meaningfully reduce crime. In England, the United States, and other Western countries, planners acting on the theory that a city’s run-down districts function as breeding grounds for crime tore those neighborhoods down and replaced them with newly designed high-rise buildings, better lighting, and heavier police patrols. Surprisingly, crime in these redesigned areas kept flourishing regardless – it barely budged.
Newman’s Critique: “Defensible Space”
The architecture researcher Oscar Newman took a hard look at this failure in his book Defensible Space and declared the whole approach fundamentally misguided. In his view, the very redesigns meant to fight crime had, in a sense, become crime’s best accomplice – because better lighting, more police, and stronger locks, on their own, don’t actually address what makes an area feel like nobody’s watching.
Newman argued that a genuinely defensible space has to awaken something in residents themselves: the sense that this area belongs to them. That feeling of ownership is what actually reduces crime, because it makes people use the space more, and makes a would-be offender reckon with the real possibility that a neighbor might recognize them and remember their face – often enough to make them think twice and simply leave. The second element Newman emphasized was active attentiveness – not just noticing something by accident, but actually calling the police the moment something looks wrong. His underlying goal was to shrink the anonymity that lets neighbors become strangers to one another, and pull them back into closer contact.
Newman and his colleagues backed these ideas with their own research, but plenty of experts pushed back. Critics argued that Newman’s framework was too mechanical for something as genuinely complicated as crime, reducing a messy social phenomenon to a handful of design variables. Some rejected the entire concept of “defensible space” outright.
Seeing It Through the Offender’s Eyes
It helps to look at this from the offender’s own perspective. The social scientists Ralph Taylor and Stephen Gottfredson argue that before settling on a target, an offender runs a real mental calculation – weighing the danger involved against the opportunity and convenience on offer.
Irwin Altman and Barbara Brown, examining the same question, found that a burglar’s mind tends to run through a fairly consistent checklist before acting:
Studying actual crime-prone properties confirmed a related pattern: areas see less crime where there is more rental housing, less street parking congestion, and fewer shopfronts crowding the block. Further research found that most break-ins happen at unfenced houses that sit visible from the main road – homes without fences, exposed to public view, get burgled far more often than homes that aren’t. Visible house numbers in large letters, an active-looking property, and clear sightlines from the street all appear to push burglars toward easier, less exposed targets elsewhere.
The 7-Eleven Experiment
This theory was put into genuine practice in the United States. The Southland Corporation, which ran 7-Eleven stores, redesigned its shops specifically to deter robbery – and consulted a former burglar and armed robber, who had spent fifteen years in prison, to design it. He stripped the stores of every hiding spot. Cash registers were repositioned to directly face the street, clearly visible to anyone walking past. Every advertisement covering the front windows was taken down so passersby could see straight into the store. Entrances were fitted with bright lighting. And the cash-handling system itself was redesigned so that only ten dollars could be withdrawn at a time, with a mandatory two-minute wait before the next ten dollars became available.
The results were striking: robberies at these redesigned stores fell 20 percent compared to competitors. The average loss per robbery at other convenience stores was $698 – at these redesigned 7-Eleven stores, it was just $45.
Further research into how offenders actually think confirms exactly why this worked. Offenders consistently look for a location where they won’t be seen and can’t be heard from outside. As one put it plainly: “I look for a place where there aren’t too many eyes.”
A Real Tool, Not a Complete Answer
Taken together, this research points to a genuinely useful conclusion: better building design and smarter urban planning really can create a stronger sense of security. But design is not a complete solution to crime. Areas redesigned to be more defensible don’t make crime disappear – they tend to push it somewhere else instead. Environmental design has no final answer to offer on its own, but used well, it remains a genuinely useful piece of the broader effort to bring crime under control.
