Two million families are on the UK housing list, and yet there are one million empty homes in Britain. So what's gone wrong? The UK (and Ireland, as it happens) is gripped by the worst housing crisis since World War II, but why, when there is so much empty property around? George Clarke is shocked by this senseless waste of housing stock. He wants to discover just how much public money is being spent to secure these empty homes. He aims to prove that refurbishing is a quicker and a more efficient way of getting people a roof over their heads than building anew. He's also setting himself the challenge of getting some families who have never had a permanent home housed by the festive season.
