I would be too worried about the plumbing to live in one over the water, really! I am spoiled, I want real plumbing, thank you, and not to worry about the water quality below me!

When I was a kid, I imagined living in a small, Walden-like hut, of course, and could do it if I HAD to, as long as I had room to sleep and room for books, but nowadays, I'd want room for Paul, too!
