world's tallest building, sky city will break ground next month in china

update (26 july 2013): the broad group, the chinese developers of the anticipated tallest building in the world, made waves with their initial announcement that they would complete the aptly named ‘sky city‘ in 90 days. in march 2013, they announced a new timeline of 7 months for the nearly 3,ooo-foot skyscraper, and the groundbreaking occurred on july 20th, 2013. just four days later, construction ground to a halt as chinese officials claim that the developers failed to get the proper governmental permissions and permits for anything besides obtaining 22 acres of land.


the broad group has already had success with the prefab skyscraper method with its 15 storey s9 building in shanghai: they delivered and assembled the 30 storey hotel structure in a mere 15 days. the extreme productivity is mainly due to a system of modules and prefabricated parts combined with a back-breaking timeline.


located just outside changsha, the rapidly developing waterfront area that will soon house a zaha hadid theater complex, the mixed use residential complex will house 31,000 people inside. approximately 83% of the vertical complex will be exclusively residential, while 3% will be reserved for office use. a hotel with a thousand person capacity and a school set to educate 4600 children is also planned for the veritable urban complex.


broad developers and broad sustainable development express and act on a serious concern for sustainable building technologies and CO2 emission reduction, touting many manifestos about green lifestyle tips and techniques. mechanisms to protect against solar gain and a network of green roofs express a commitment to the green cause, irrespective of scale. the 220 storey is set to top out at a height of 838 meters and cost a relative small sum of 628 million USD; a fraction of the cost of the current tallest building in the world, dubai’s burj khalifa. that mega structure cost about 1.5 billion USD and was built in an already extraordinarily fast five years. sky city ‘s statistics are particularly remarkable because the project aims to posit a solution to a larger goal of extreme urbanization and population growth both cheaply and with regard to environmental concerns. the site selection alone proposes a long-term metropolitan spread, with the assumption that changsha’s urban trajectory will engulf the megastructure. perhaps 200,000 tons of prefabricated steel components will result in a resolution to long-standing problems in urban development and alter the profession and priorities in architecture at large.

in a committment ot CO2 emission reduction and a sustainable lifestyle, mechanisms to guard against solar heat gain will be in place



a network of rooftop gardens is in line with the green lifestyle proposed

  • Tallest tower of the world in just 7 months….. unbelievable. .. construction will be complete in 90 days…. wow.. amazing.
    its going to be part of all the record books.

    amod says:
  • it’s not how, but why?

    s. lee says:
  • the Chinese Version (Made in China) of Burj Khalifa!!

    Alain says:
  • The world’s tallest, dullest building.

    jumt says:
  • Awful… but interesting!

    d. pi says:
  • It will be exactly as described, a lego building. There is a difference between constructing a prefabricated home and a home with more sophisticated design elements. Which would you want to live in?
    Also, why do this? I particularly enjoy the rotten text using the words sustainability and ‘green roof’.

    Ron Smith says:
  • OMG,, a much bigger, but worse version of the empire state building. If this building will stay for hundreds of years or so,, why building it up so quickly, but careless about the design? After all, people in the city will have to stare at it everyday…. If the client wants to save money, build it lower. Having 10 thousand windows that looks exactly the same isn’t the solution.

    twny says:
  • It might be good if you were storing boxes or something. But for real people to live in a building like that, I am not entirely convinced.

    idle_crane says:
  • Certainly the Changsha region economy will support this enterprise plus the future Hadid complex. China has seen enough ghost buildings and complexes brought about by rapid economic growth and ironically lack of economic feasibility studies relative to some very ambitious and spectacular projects. Hopefully this sky city project fulfills its creators’ objectives and escapes being another ghost building, world’s tallest at that.

    nelsondreyes architect says:
  • i really would like to see floorplans here. 83% apartemts. that’s not quite easy.

    d.teil says:
  • McSkyscraper.

    Horrible says:
  • 100 days 1km?

    Ro says:
  • i am sick of claims to build the world’s tallest building. not only did they originally state this would be done in 90 days (obviously absurd) it was also supposed to be completed by 2 months ago. this proposed building is a total fantasy that will not come to fruition. in fact it would never be built in a place with real structural laws. just more propaganda from china.

    usarch says:
  • 90 days… Probably, Just the shell… No lifts, no mechelec, no running water, no internal walls.. Just an empty toothless exterior that will show the world what a great POS china is. oh and we hate spires, they prove nothing… Just 2 boys showing off who can piss further.. It needs a helipad at the very top.

    Desk says:
  • The worlds tallest middle finger to its surroundings

    Dr.H says:
  • There are Interesting comments so far and many on point. The main theme is that the building is boring. The interesting information on this is that the building is modulated in such a way that it can reach this height. That by itself is very interesting. The repetitiveness of the systems creates the nature of its boring appearance. The inside layout is something i would like to see. However, my biggest issue is “Why”. The building in mass is far too much and overwhelms the rest of the environment of buildings and geographic locations. The idea of highest today is really quite childish even for the Burj Khalifa and others that build for name recognition. The issue about height is about image and even the boring twin towers in New York stood for a symbol of financial power and as we know even more so now. What is built in their place will be far more significant and important to the world of Architecture than the constant search for the highest building. But, because one has the tallest structure has the tallest structure and means little in today’s Architecture. Besides, the air in China is so dirty, no one can see above the 20th floor either and looking out is going to look like a dirty cloud bank.

    HHM says:
  • Well, you would have difficulty accusing this building of being associated with anything even remotely related to this thing I’ve heard referred to as “architecture”..

    archi says:
  • We’ll see if they can stick to what they’re saying… will be interesting…

    ddds says:
  • Well at least doing this will put out more ideas for people to make better there own, I mean a city in one spot sounds cool, but Japan’s skyCity sounds cooler and more… Better;)

    Someonealsoin this world says:
  • I think there area a lot of good things about this building.
