A notorious drug den is to be transformed into a community space by 1,000 West London children.

The children have taken part in a special competition to design a multi-sensory garden at a crime hotspot, which used to be frequented by alcoholics and drug addicts.

The Wolf Fields project spearheaded by Southall-based charity A Rocha UK will see winners from four local schools presented with prize plaques at an open day on the site this Sunday.

Entrants came from Wolf Fields Primary School, Norwood Road, Clifton Primary School, Clifton Road, Three Bridges Primary School, Melbury Ave and Norwood Green Infant and Nursery School, Thorncliffe Rd. They had to create a design on A4 paper using pencil and crayon, to help visitors engage with Wolf Fields using different combinations of senses.

Conservation Director Andy Lester said: "In the past, local police were having trouble patrolling the area – which was basicallyu a drug den used for drug taking and binge drinking. But now, once work is completed, the site will be used for orchards, bee hives, pond dipping and a wild flower meadow."

Environmental Education Officer David Melville, said: "There were some beautiful pieces of artwork. One student was a budding landscape designer, and another produced a garden that reflected their school's colours. Their ideas will influence the final design of the sensory garden, which will enable those with learning difficulties and impairments to enjoy the natural environment of Wolf Fields."

As well as the prize-giving ceremony, this Sunday’s open day will also include a ‘spider drama’ to underline the message that insects matter. Other activities will include – bug hotel making, a demonstration bee hive, a bee story by a local storyteller, tours of the site in a nature trail style and refreshments.

A Rocha UK team members and volunteers will be joined by representatives from schools and churches, along with local residents. ‘People will be able to see the site, our plans for it, and to talk about why we’re trying to transform it,’ said Conservation Officer Becky Vickers.

The open day will run from 2-5pm, with the ceremony and welcome at 3pm.

A Rocha UK is a Christian conservation charity working for the protection and restoration of the natural world.
