Yamasaki, along with Edward Durrell Stone, designed some of the most unusual skyscrapers.
Often vaguely gothic, Yamasaki was trying to add a human scale or visual interest to these buildings.
Maybe, Yamasaki, Stone, and Morris Lapidus were the first post-modernists.

Interesting building.
truly unusual
This isn’t a Yamasaki building. I’ve been researching his work for years and am currently writing a book, and can say with 100% certainty that Minoru Yamasaki did not design the building at 1200 Brickell Ave.
This unfortunate myth has been around for years but is easily debunked.
