Sky City (Chinese: 天空城市; pinyin: tiānkōng chéngshì), or Sky City One, is a proposed supertall skyscraper approved for construction in the city of Changsha, Hunan in south-central China, to be constructed by the Chinese construction company Broad Sustainable Building.[5]
If built as planned and to schedule, Sky City would be likely to be the tallest building in the world at the time of its completion, with 220 floors and a total height of 838 meters. The construction plan calls for it to be built from pre-fabricated units constructed on site in an unprecedentedly short period of 90 days.[6][7] BSB's plan is to assemble 95% of the building in its factory before a single shovelful of dirt has been moved at the actual build site.[8]
The proposed building will have total floor space of 1.2 million m2. The main building will be 1.05 million m2, a basement of 130,000 m2 and a 3–7 floor high annex of 35,000 m2.[2]
A cost estimate of $1500 per square meter[9] of floor space would make Sky City considerably cheaper than the similarly tall Burj Khalifa ($4500 per square meter).
As of October 2012, BSB has received approval from the government[8] and has stated that they are still going to begin construction in November, but announced a new build time of 210 days. This puts the date of completion at May 2013.[10]
On November 16, Juliet Jiang, senior vice president of Broad Group, said in an interview that the company will adhere to its previous time table of building five floors a day and completing the building in a 90 day time frame. She also said the building is still waiting for government approval.[9]
Later in November, the company announced January 2013 as the start for the construction.[11]
Although structural details are not available, outside architects have expressed doubts that a modular design would have the stiffness on lower floors to withstand the wind loads imposed by such a height, without unacceptable amounts of sway,[12] or that the building could be built without high-strength concrete, whose curing time would preclude such a rapid construction rate.

Or they can drastically reduce the residential capacity of the tower, leave more room for public space. It's a proof of concept project anyway, as long as BSB doesn't lose too much money on it then it's fine.

Honestly, in my opinion...the building look very ugly.

I can say, it's like a person from backwater country with very "laughable" personal taste choose that kind of design.

I understand if the Board Group want to build it, more as a promotional for their Board Sustainable Building product, to show to the customers, the reliability and capability of their products.

But for the sake of China image and the architecture world, I'm suggesting to halt the project and redesign the building. Changsha people should not be fooled and shamed by this "ugly" tower, they should protest on the street as HK people do!

Most of the skyscrapers I know, have the same skeleton construction from one to another. The different is just at the shape and outer coat. For the skeleton, Board Group can use their Board Sustainable Building part, but for the outer coat layer, they add several accessories just like any other tower to make it more beautiful. I do believe they can do it.

If mainland Chinese have the high IQ and education prowess as many experts said, they will agree with me and start to protest to stop ugly building being built.

I agree that it doesn't look very pretty. But as a concept it is an amazing project for both Broad group and Changsha as a city. Seeing it will probably create lots of jobs. Not just during the construction (which won't be that long), but also at the assembly plants Broad Group is building when they are hopefully going to start mass producing buildings of this type. Buildings which will have a much higher standard than alot of the other commie blocks you find around rural China or its tows/smaller cities.

construction being halt,according to wuhan city authority.main reason was in case of fire, it will be impossible for fire men reach the top floor,
the whole project may have to abandon, and may opt for 'mid'size" skyscraper.

They have real men in Changsha :lol: .

A hotel and restaurants occupy the top floors. And the 'building' is to have a 3-hour fire-resistance rating.

I hope it isn't true but CCTV just reported that the Sky City project has been stopped, possibly cancelled.

Apparently Broad Inc. never reported the construction to city planning, the official news bulletine says that construction approval procedures were never submitted to the authorities.

Very strange and disheartening indeed with all the hubhub and claims.
