Olympic legacy project somewhereto_ , which gives 16-25-year-olds access to unused spaces in order to explore their talents, has gained Prime Ministerial support, being given the keys to 10 Downing Street to record a promotional film.

Launched in July by youth engagement agency Livity, in association with Channel 4, somewhereto_ (sic) has already unlocked almost 300 spaces, donated by private, public and charitable organisations, for use by young people. The project is funded in part by Legacy Trust UK and charity supporters include Catch22, Land Aid and UnLtd.

Downing Street was lent to the project to promote how space can be used in alternative ways. Free-runners, boxers and spoken-word artists used the iconic building to campaign for more spaces in a promotional film shot within its walls and garden.

The project is a great example of the Big Society at work, said Prime Minister David Cameron lending his support: "somewhereto_ is a fantastic initiative to help young people find the space they need to develop their passions. It is a great example of the Big Society - connecting businesses that have space they can spare with people in their community who have a dream they can use it for.

"If 10 Downing Street can open its doors to something as adventurous as free running, I hope it will inspire other people to see what their building could be used for," he said.
