One of the most unusual corners of London is the remarkable Garden Barge Square (Photo: Drew Bennellick) where a community of barge owners live right by next to Tower Bridge. These historic moorings date back 200 years or more. Gardens have been created on the decks of many of the barges to form a kind of floating garden square. But be warned barge living is not as romantic it first might seem. The Thames is cold, damp and grey in winter and the cabins are cramped. See more on Tree Hugger.
