Amazing Spaces: Shed of the Year

George Clarke presents this year's competition. The first episode features normal sheds, which include a miniature railway shed, a makeshift observatory with a retractable roof and advanced telescope, a shed that doubles as a boat and a home cinema that is also home to a collection of movie memorabilia. The judges also cast their eyes over some environmentally friendly builds, including a shed shaped like an owl, a highland bothy, a geodesic dome and a building made entirely out of mud.
