Eco-lodge and Houseboat

George drops in on one of the most expensive builds ever seen on the show - a stunning, glass-fronted eco-lodge seemingly floating in mid-air. He also meets a newly married couple who are trying to turn an old boat into their first ever home on a shoestring budget, visits a Japanese-inspired micro-home in London and takes an inspiration trip to Israel to see one of the most unusual, hand-built homes he has ever seen.
