Designers have teamed up with the police to create the ideal ‘crime prevention garden’. Hannah Stephenson finds out more.

You may have locked your doors and windows, installed a burglar alarm and prompted neighbours to keep a watch over your home while you’re on holiday - but have you considered how the style and design of your garden could help deter thieves too?

At this year’s RHS Hampton Court Palace Flower Show, designers Lucy Glover and Jacqueline Poll had a crime prevention garden that was both stunning and secure, a collaboration between crime prevention initiative Secured By Design with Capel Manor College and the Metropolitan Police.

The striking urban garden featured green security measures, such as columnar trees and prickly plants, but also a calming atmosphere and soft relaxed planting, including beautiful perennials and grasses.

“Some 75 per cent of all burglaries across the Met are via a rear garden. Those with criminal intention are looking for opportunity,” says PC Leslie Gipps, a Designing Out Crime Officer with the Metropolitan Police.

“What we do in Secured By Design is put in those layers which make it harder for the criminal to spend any real time trying to break in. They will just leave that garden and go for one that’s simpler.”

Want to add some crime-preventing layers to your garden? Here, the garden designers and Met officers recommend 11 ways to help deter criminals from targeting your property...

1. Prickly plants

Create a hedge of prickly plants, such as Osmanthus, pyracantha or berberis, next to boundary fencing, which can act as a layer to deter thieves.

In the crime prevention garden, the designers used Osmanthus heterophyllus, a shrub with sharply toothed leaves (similar to holly) under the windows, Berberis thunbergii f. atropurpurea, with stems that bear spiky spines, and pyracantha, a dense spiky shrub which is great grown as a hedge. Pyracantha will grow in any soil and is fast-growing.

2. Green screens

Boundary fences can be the first line of defence, and a good bet is a wire mesh which you can adorn with ivy or other ‘green screen’ - these look pretty but also act as a good deterrent. After all, a wire fence is unlikely to take someone’s weight.

Gipps explains: “By attempting the fence, thieves would draw attention to themselves and possibly leave their DNA behind. They know that, and can see it from the other side of the street. So it’s crime prevention through environmental design.”

3. Dusk-till-dawn lighting

Install dusk-till-dawn low-voltage lights to ensure visibility in the garden at night. Stone effect solar lights will provide additional lighting and sculptural interest throughout the garden. “If your garden is lit through the hours of darkness, people with criminal intention don’t want to come into a lit environment,” says Gipps.

Householders often ignore sensor lights, thinking they’ve been set off by a fox or a cat. “Ten-watt LED lights are fine. We prefer white LED lighting, but you can choose a less bright option,” Gipps adds.

4. Gravel around the house

Gravel is noisy when walked on, so having it around your property means you can hear any uninvited visitors approaching the house. It also alerts dogs.

5. Curtain planting

“The aim is to have rich colour in the garden but not big solid shrubs that somebody can hide behind, so ideally grasses and other plants you can see through,” says Glover.

Light planting, such as grasses and ‘curtain planting’ with Verbena bonariensis and Sanguisorba canadensis, allows the homeowner to see through the planting.

6. Narrow trees

If you want to include architectural interest, use columnar-shaped trees, which are more difficult for intruders to hide behind and also difficult to climb.

7. Roses

Thorny roses can be used to great effect by training them over pergolas and other supports, which thieves might otherwise climb. The designers used rotating bars on their pergola to prevent thieves climbing. Roses will also give you scent and colour.

8. Green roof

Consider a green roof on your shed featuring spiky plants. The designers have planted a swathe of sedum on their shed roof, interplanted with aloe, a sharper specimen. Any intruder putting their hands on the shed roof would get a handful of prickles.

9. Shed security

Don’t leave tools outside, but also make it difficult for thieves to gain access to the shed, where you store them. Gipps explains: “The typical garden shed will come with a cheap padlock. We advocate that you have two locks - one a third up, the other a third down - with robust hinges and secure high-quality padlocks. You need robust hinges, coach-bolted through the fabric of the door.”

10. Secure garden pots

Thieves also use garden pots to break windows to gain entry. The best way to stop this is by using really heavy, large pots which are very difficult to lift. Keeping your plants well watered will help keep them heavy too.

11. Mark your property

Put your own forensic code on your garden items. Gipps recommends SmartWater (www.smartwater.com), a near-invisible, traceable liquid which gives your equipment its own unique forensic code, allowing items to be traced back to you, and the criminals back to the crime.

The code is registered to your home and stored on the SmartWater database. Once applied, it lasts for a minimum of five years, enabling stolen goods, if recovered, to be more easily identified and returned to the owner.
