George Clarke presides over the 2017 Shed of the Year competition, beginning with the cabins and summerhouses category. Among the contenders are a mushroom-shaped shed and a pink and turquoise construction inspired by a Los Angeles pool house. This year's contest will feature a new category, for unusual sheds that push the boundaries of construction in ingenious ways.

George Clarke presents the Pubs and Entertainment and Unexpected categories. Unusual structures featured include a hedgehog rescue centre, a West Country whisky den, a recreation of the Tardis from Doctor Who, and the UK's smallest cathedral.

George Clarke presents the entries in the Historic and Workshops and Studios categories. Among the finalists in these areas are a shed where a bestselling trilogy of novels were written and a build in Wales used for making prosthetic limbs for children around the world.

George Clarke presides over the final categories, for eco-friendly and budget sheds. Candidates include a stargazing hut in the Scottish highlands, a replica of a Hobbit hole from The Lord of the Rings, a shed built entirely from discarded materials, and a family home that cost just £1000. The judges will then decide which of the eight finalists is this year's winner.
