World's Tallest Building Being Constructed in China

China has started to build the world's tallest building. Sky City in Changsha in central China will start to be built in July 20^th and is projected to be 2,749 feet reported CNN.

To date, Dubai's Burj Khalifa is 828-meters and the world's tallest building. It took five years to build Burj Khalifa and is set to only take 10 months to build Changsha.

"Fast construction claims from Broad Group, the Changsha-based construction company in charge of the build, have elicited strong reactions from China's "netizens," as well as experts," reported CNN Travel.

There are more than 10 cities in China that are planning to build something taller than the World Trade Center in New York which is 1,775 feet.

"The site, which defines "skyscrapers" as buildings taller than 152 meters (498 feet), also reports that China currently has 470 skyscrapers, 332 under construction and 516 planned but unconfirmed.

That means by 2022 China could have a total of 1,318 buildings higher than 152 meters, more than twice than expected in the United States," reported CNN Travel.

In Australia, there are plans for the biggest skyscraper in the Southern Hemisphere.The Huffington Post reported that the skyscraper has been called "Australia 108" and its plans would be to become 388-meters which is approximately 1,273 feet.

The project is expected to cost $622 million, reported CNN and will take a projected three to four years to complete. Victorian Planning Minister, Matthew Guy approved plans for the project this week that will be built on Southbank Boulevard.

"When complete, it'll surpass Melbourne's Eureka Tower (297 meters) and overthrow Q1 (322 meters) in Queensland's Gold Coast as the tallest building in the southern hemisphere," reported CNN.

The design is being done by Fender Katsalidis Architects who also designed Eureka Tower. It will include 108 floors of residential apartments, a "six-star luxury hotel" and a sky bar as well as recreation facilities.

"Australia 108 has the ability to define Melbourne and signify our coming of age as a dynamic and progressive international city," said Nonda Katsalidis to CNN who is co-designing the tower. "Nothing like this exists in our part of the world."
