Unbuilt buildings

Hi, i have a couple of ideas but the one i am most interested in the information is limited.
1. The Sydney Opera House had many political issues with it. Jorn Utzon was forced to resign before he finished the interior of the halls and theatres. [i'm very sure you know this already] so i was interested in modelling what the interior was supposed to look like. [i do know for a fact that this was accomplished in a warehouse some years ago]

2. House of two horizons, 1973, Raimund Abraham [American project] look very interesting and challenging because it was a hypothetical project.

3. Aerial Restaurant, 1929, Norman Bel Geddes. It was abbandoned, but very different, looks like a space station.

4. Wrapped Building No.1, 1968, Christo. looks so interesting and maybe something that would fit in a very innovative emerging country of today wanting to be different.
