New series. The architect returns with a fresh selection of ingenious and eccentric builds created by pioneering small-space designers around the UK. Throughout the series George also travels through Japan, where ground-breaking design and innovation blend seamlessly. To begin George visits a canal boat conversion in Dudley, a cattle trailer in Yorkshire being turned into a luxury holiday camper and - in Japan - a dynamic, multi-coloured open-plan space. He and right-hand man Will Hardie also get their heads together to build their own four-ton treehouse.
