1. Shanghai Tower, China
Not only is this the tallest twisted building by far, but it is also home to the world’s highest observation deck located within a working office building! If you think that all sounds amazing it is also home to the world’s fastest elevators at a top speed of nearly 46 miles per hour (74km/h)!
2. Lakhta Center, Russia
This beautiful mixed-use non-residential construction has slipped behind its own competition date a few times but is pretty much finished. When 100% complete it will have 87 floors and 34 lifts!
