Amazing Spaces: Shed of the Year' is a celebration of one of the symbols of British eccentricity: the humble garden shed, a hallowed land of splendid isolation in nature, and often an arena for creativity. The competitors have all expanded the limits what a shed can be, and what they can be used for. George Clarke pays a visit to the entrants, and has seen recreations of the Millennium Falcon, a museum for antique lawnmowers, and a travelling shed that can reach 80mph. The finalists are the top four sheds entered into each of the eight categories which include Eco, Unexpected, Pub & Entertainment, Workshop & Studio, Unique, Cabin & Summerhouse, Historical and Budget.
