World's Coolest Buildings
Architect: Rem Koolhaas and Ole Scheeren
Why It’s Cool: No two layouts of its 55 floors are the same. Only the Pentagon is a larger office building. Even in a country pushing architectural boundaries, this squared-off doughnut seems dizzyingly unique. And next fall, visitors could stand on glass discs in a cantilevered floor and stare down 500 unencumbered feet to the street (though a February fire at the Mandarin Oriental hotel next door could push back the already-delayed opening). “Amidst all the skyscrapers there, it’s relatively low,” said Koolhaas in 2006. “It will feel accessible.”
How to Visit: 11 Fuxing Road; under construction, but much to see from the streets. Tours may kick off when it opens.
