Plot: 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
