This is the Capital Gate, a 525-foot tall tower that leans 18 degrees to the west, 14 degrees more than the Tower of Pisa. And unlike many of these spectacular projects, this one is actually well underway in Abu Dhabi, as you can see in this image:

The building—which will house a 5-star Hyatt hotel—can lean this much thanks to its steel exoskeleton and 490 piles drilled 100 feet into the ground, designed to compensate for gravity, wind, and seismic pressures caused by its peculiar shape. I wonder who is compensating for all the gravity, wind, and seismic economic pressures generated by all this crazy developments in the desert. [ArchDaily]
