My favorite design might be the Chrysler Building's. The concrete color though kind of turns me off, because it just blends into everything else in NYC. My favorite then I think is the Sears Tower. The multiple sections prevent it from being brutalist. I like that it is black rather than concrete (somthing I think Chicago does far beeter than NYC). I dont care much for the John Hancok building whih seems to be on more coins and books.
