I found a few pictures of some other strange houses.
This first one looks as if it is made up of cargo containers. I would be afraid to stand so close to the windows or put any heavy furniture in that room. I also would have built it right on the edge of the water so the top would hang right over the water.
This next house is very precariously placed. I would hate to be sleep-walking around the yard. I think it would be cool to have transparent floors so you could watch the boats go by.
