Bolt-hole, Shipping Containers and a Caravan

George continues his exploration of the world of small builds, meeting a man planning a bolt-hole in the Lake District, and visiting a community in Hackney, London, that lives and works in customised shipping containers. He also travels to a home in nearby Shoreditch where the kitchen has been moved onto the roof, and finds out how an Oxford resident has turned his back garden into a party palace using a caravan.
