As statistics show more young people are becoming homeless in the UK, a new play questions why more is not being done to help those forced onto the streets.
Government figures show the number of people sleeping rough in England has increased by a third since 2010.
In London alone, 6,437 people slept rough during 2012-13, a 62% rise in two years.
Campaigners say there is a risk this trend could continue, given youth unemployment, the economic downturn and the pressures on low income families, combined with changes within welfare reform, reduction of public services and the general squeezing of housing supply and affordability of accommodation.
The official figures do not account for the hidden homeless.
Three months after his 18th birthday, Leo was forced to sofa surf for nine months until he received help from Centre Point.
He told Sky News: "I feel lonely and like I don't really have a voice. I'm not really accountable for anything despite going to college. I don't feel like a real person."
Ministers insist they are taking homelessness seriously and have pledged £400m to councils to tackle the issue.
Communities Minister Don Foster said: "We have one of the strongest safety nets across the world. If you look, for example, at rough sleeping in London, out of the 6,000 people in the last 12 months only 14 of those were under 18."
After spending 18 months speaking to young people at an east London hostel, director Nadia Fall has used their words for the basis of a new play called Home, which opens at the National Theatre this week.
"There is seriously a whole generation that will not understand what it means to call your home in the way that we do - somewhere of your own, either to have, own or to even to rent," she said.
