Here is a picture I recently took which I though Satguru might be interested in since he likes looking at houses. This house was built in the 1970s in a quiet cul-de-sac in suburban Perth (not far from where I live) and has always been a bit of a curiosity among the locals.
To the best of my knowledge, only two of these "houses of the future" were built - this one and another one in a different suburb which was built up on "stilts" (for lack of a better term) and really looked like a flying saucer. That second one no longer exists. This house is a little run down and neglected now, although people do live in it.
The only housing I have ever seen more unusual than this would have to be the cube houses in the Netherlands.
