I uploaded some pictures of a house in development I was lucky enough to look around. This home is is the $25 million price range, and everything is custom-made, even the $17,000 doors. The owner is a casino owner, and was a very nice guy, which surprised me.
The thing that strikes me is how much it looks like a Q3 map, but the real influences are from Native American culture (the name comes from this too) such as parts of the house inspired by the shape of the Teepee. Also, the house was designed to work with nature, using a few of Frank Lloyd Wright's ideas. Unlike Lloyd Wright, however, they've been landscaping extensively and placing boulders and hills in order to make nature "more ideal".
Also, in something that, ironically, also relates to Q3 mapping, the caretaker complains that the building focuses too much on aesthetics, and the 'flow' of the house and practicality have taken a back seat. So it's got crap gameplay, but it sure looks nice.
First page is exterior shots, 2nd and 3rd are interiors. Look out for the 'detailing'; there are lights carved into rocks, custom triangle floor grates, and custom stair light trim, and more! Enjoy.
