Library Van & Second World War Bunker

In Gloucestershire, two young artists are converting an old district library van into a mobile home and art studio. Also, Steve and Marie have found a bunker from World War Two under their garden and are turning it into an office, with an ingenious motorised lift to bring light into the space. In Japan, George visits a town that recycles 80% of all waste, including a pub where everything is recycled, from the windows to the beer itself. And George and Will's incredible supersized tree house is ready to be installed on site.
