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.

George Clarke and the judges visit the nominees in the Unique Sheds category, which include a Japanese-style treehouse, a shed built in a tree 16 metres in the air, a gothic folly and the smallest shed in the competition, which forms part of a model railway. They also examine the entries for best historical shed, including an Anglo-Saxon dwelling, a 1950s diner, a writing hut that once belonged to George Bernard Shaw and a corrugated cottage from the Second World War.

This year's contest draws to a close as George Clarke and the team visit contenders from the Cabin and Summerhouse and Workshop and Studio categories. Among the spaces highlighted are a converted burger van, a tiny pixie-themed cabin, a mock-Tudor structure with a psychedelic interior, a state-of-the-art photographic studio, a spaced carved using a chainsaw, and an extraordinary potting shed. With the last round of visits concluded, it is then left to George and his fellow judges to determine which of the winning entries from the nine individual categories should be named the Shed of the Year. Last in the series.
