P H E N O M E N A L , isn´t it? Even though I probably couldn´t deal with an all white (and I mean ALL white) home (unless it is a vacation home only) but I adore the clean and super sculptural geometry of this artwork. The tapered walls are superb and I like the sliding door to reveal another opening, either opening or closing the facade entirely on the middle floor. Have a look here for more images and some floor plans.
