3. Infinity Tower – Dubai, UAE
The Infinity Tower is the world’s tallest high-rise building with a twist. The unique and almost complete skyscraper spirals an amazing 90˚ from its base to its crown, 305 meters (1,000 feet) above the ground. The 80-story high residential tower has dynamic waterfront views, which depend on its elevation. Amazingly, there is not a single structural pillar anywhere inside the building.
