George meets a teacher creating a bolt-hole in the Lake District by following an increasingly popular trend in the UK of buying his own plot of countryside and doing the building himself.
George visits a community in Hackney who live and work in customized shipping containers and is astounded to find an architect who has moved his kitchen onto the roof of his house.
In Oxford, Bernard Fontannaz has lifted a 1971 airstream caravan into his back garden to create the ultimate party palace - and it doesn't break any planning laws.
And on his own project, George bids farewell to the nostalgia of his caravan's 70s interior and takes the plunge with a risky but ingenious way of creating extra space for the family.
