Piano Raft – owned by Ben Cummins in West Yorkshire, Saltaire Perhaps the most unusual of all of the shortlisted contestants is this self-made floating shed. Not only has the creator, Ben, spent the past five years building the structure piece by piece using reclaimed materials he finds on his journeys, but he has also manually pulled his shed on skis from Liverpool to Leeds. If you thought that may not have been complex or difficult enough, he has also started to transform it into a musical instrument.
