The first episode includes the Unique shed category, which features a 21ft-wide replica of a tea pot, a Titanic museum and a cinema shed with over 3000 films. The Eco category features a garden shed with an allotment built on the roof, a shed made out of 5000 wine bottles, an egg shaped studio and a glass shed built over a pond, which cost just £250.

The competition to find the country's best shed continues with the Summerhouse/Cabin group, which throws up a replica 18th century US frontier cabin, a Gothic grotto decorated with 50,000 seashells, and a scaled down Elizabethan lodge. In the Workshop category, a 1930s garage, complete with classic car restorations, battles it out with a graffiti artist's shed with its own gorilla, an extraordinary bird box production line, and the smallest shed in the whole competition: a music venue with room for just one performer and one audience member.

As the competition to find Britain's best shed reaches its climax, George Clarke and his fellow judges look at the final groups of shortlisted sheds battling it out for a place in the grand final. The 'Normal' sheds prove anything but, with one of the smallest discos in the world up against a Dad's Army themed shed complete with air raid siren, as well as a 1970s amusement park in a shed with a 12-foot working Ferris wheel outside. The judges cast their eyes over the most pleasurable category in the competition, the Pub Shed, before they decide which of them most deserves the overall prize of Shed of the Year 2014. George also visits last year's winner: an upside-down boat shed.

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.

George Clarke introduces the nominees in the Pub Sheds category, including a pirate-themed structure, a gin distillery, a biker pub that once housed a helicopter and a nightclub with a collection of shrunken heads. He also looks at budget sheds, featuring a hillbilly hut on wheels, a garden pavilion made of firewood, a Nepalese mountain hut and a shed made from the ruins of beach huts.

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.

From hundreds of entries received, just 32 have made it on to the judges' shortlist for 2016 - and only one will take the ultimate shed accolade. George Clarke begins his annual quest by turning his attentions to those sheds in the Unique and Historic categories. These include a shed that rotates 360 degrees to follow the sun and another that can hit the road, clocking in at speeds up to 90mph. Also on display are a faithful replica of an Anglo Saxon longhouse and a Vietnam War bunker in Staffordshire.

Architect, presenter, lecturer and writer George Clarke's mission to find Britain's 2016 Shed of the Year continues as he and his fellow judges turn their attention to the Eco and Unexpected categories. Eco includes a mud hut in Norfolk and a shed on wheels, while featuring in the new Unexpected category is a shed located on a flood plain designed to rise up with whatever water levels surround it. There is also an allegedly haunted shed, so viewers might wish to make sure they are not alone before tuning in.

The 2016 competition arrives at its half-way point, with the turn of the most popular category - Pubs and Entertainment sheds. This fiercely contested group includes an entire Wild West town built out of sheds up in Aberdeen, a faithful replica of a Polish mountain drinking den in rural Ireland, and a nightclub in a Hackney with a truly one-of-a-kind owner. Meanwhile, among the shortlisted sheds in the Workshops and Studios group are a blacksmith's smithy and Star Wars shed. Presenter George Clarke also meets a man with over 300 lawnmowers.

The 2016 competition continues, with the Budget category, which includes a colourful beach house made for just £20 and a shed that actually earned its owner £100 in profit. The Cabins and Summerhouses group features a classic van and a dream structure in an allotment. Next, presenter George Clarke and his fellow judges are tasked to choose one shed from all the category winners across the series to crown as the overall winner. Last in the series.

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.
