Stella, believe it or not but I almost bought one of those bungalows a sort while back. My company was selling beach-front and over-the-water 'huts' in one of the Tahitian lagoons and the water ones included a glass floor and a small "chute" so your could watch as you fed the fish.
Each one bedroom hut included all the modern conveniences plus a small outrigger so you could get to the 'market' without the need to walk along the beach.
And at that time they were offered for less than $40,000 each ... Way less if I recall correctly!
But within a couple of days some major publication company bought them all up and only left a few of the less preferred huts available ... not on the beach, not on the water, but only a few yards away, so no one in the office made an offer.
And I don't regret it in the least because such a life style does get boring after a couple of weeks anyway.
This 2nd shot shows where I used to live. I spent many a day picnicking on that sand bar and swimming with some dolphins and many colorful tropical fish, but doing the same-o same-o everyday gets to be too damn routine and eventually very boring.
