Zhang Yue house

One of China's richest person lives here. Zhang Yue is famous for building skyscrapers and other complex structures around the world within a very short time.

His aim is to build Sky City One in record time of less than a year while he has plans for an even broader project of building 2km tall tower

"Sky City" - as he has dubbed it - can fix many of the world's pollution, congestion, transportation and even disease problems by completely purifying the tower's air. The 838-meter-tall building (10 meters taller than the Burj Khalifa in Dubai, currently the world's tallest) will hold schools, a hospital, 17 helipads and some 30,000 people. It will, indeed, be a city in the sky.

His dreams don't stop there.

Pinned up on his office wall are plans for a project even more audacious - an almost preposterously massive building two kilometers high. When asked to estimate the odds of this 636-floor giganto-scraper ever being built, Zhang responds without hesitation, "One hundred percent! Some say that it's sensationalism to construct such a tall building. That's not so. Land shortages are already a grave problem. There's also the very serious transportation issue. We must bring cities together and stretch for the sky in order to save cities and save the Earth. We must eliminate most traffic, traffic that has no value! And we must reduce our dependency on roads and transportation."
