The Commune, Beijing

First phase completed 2002, expansion scheduled for completion in 2010

Even if the Commune didn't sit beside that wonder of the ancient world, the Great Wall of China, it would still qualify as a wonder. The complex includes houses by 12 of Asia's leading architects. It was conceived by married real-estate developers Zhang Xin and Pan Shiyi, who gave each architect a $1 million budget. Shigeru Ban, the Japanese architect most famous for the paper houses he designed for refugees of the Kobe earthquake, designed the Furniture House, featuring the laminated plywood typically used for modular furniture, and China's Yung Ho Chang created the Split House, which takes the idea of a boxy dwelling, slices it in half, and spreads it out like a fan.

The Commune is now operated as a boutique hotel by the Germany luxury hotel group Kempinski, which is responsible for an upcoming expansion, which will feature 21 homes (including replications of the originals). One element will remain untouched in the new development: the Commune's private pedestrian trails, which trace untouched sections of the Great Wall.
