Porsche Museum in Stuttgart

You're standing at the Porsche Museum in Zuffenhausen, a district in the north of Stuttgart. It sits on a prominent junction right next to Porsche's headquarters. Now look up. That big white building seems almost to float. That's the idea. The exhibition block is nicknamed the Flieger, the flyer, and it weighs a hefty 35,000 tons. Yet it rests on just three cores: one shaft holding the lifts, and two cores carried by Y-shaped columns.
