Glass Lodge and a Doggie Campervan

George Clarke looks back at some of the best and most eccentric entrants from the last three years of Amazing Spaces Shed of the Year. From a giant green tea pot to a shed that motors along Britain's rivers, George rediscovers the extraordinary things people have created from the humble garden structure. There's also a shed built from old wine bottles, as well as a faithful replica of a Japanese tea house built in an Essex garden.
