Gallery: Sky City: World’s Tallest Tower to Break Ground in June

 
Using just a portion of their site, Sky City will have the most extreme urban density we've ever seen. But the difference between Sky City and say, Hong Kong, is that the tower is surrounded by parks, meaning that every resident has access to open space.

Sky City will be prefabricated off site in three months, and it will then be assembled in just seven months. Reaching up 838 meters (2,749 feet), the 220-floor tower will feature residential, office space, organic farms, recreation spaces, schools, a hospital retail and much more. The tower will house 4,450 families in apartments ranging from 645 square feet to 5,000 square feet with 92 elevators at your disposal to reach them. As its name suggest, Sky City will be a vertical city that will accommodate 100,000 people and offer everything that is needed — water, electricity, sewage (unlike the Burj Khalifa), open space, schools, health care and more.

Using just a portion of its site, Sky City will be home to the most extreme urban density we’ve ever seen. But the difference between Sky City and say, Hong Kong, is that the tower will be surrounded by parks, meaning that every resident will have access to open space. The prefabricated tower will include many energy efficient strategies like 8-inch thick insulated walls, triple glazing, exterior shading that cuts down on cooling by 30 percent, and a co-generation plant that will use waste heat from power generation for heating and cooling. Transportation will be provided by low-energy elevators and for those who want to walk (or get exercise) there is a six-mile-long ramp running from the first to the 170th floor.

According to Treehugger, construction is set to begin this June and is expected to be complete within seven months (210 days). The rapid pace of construction and the overall design for such a massive skyscraper could be a cause of concern, but if Broad Sustainable Building pulls it off, it may show the world how sustainable density can be achieved on a massive scale. The company assures that the building will be able to withstand a Magnitude 9 earthquake and will have a three-hour fire resistance rating.

Lloyd Alter at Treehugger sums it up well: “This is going to be a controversial vision of sustainability; putting 30,000 people in a single building is a hard sell. It is not the bucolic version of green living that most people think of. It certainly is a lot higher than what I have called the Goldilocks Density. But it is the logical extension of the Edward Glaeser / David Owen thesis that the way to go green is to go up, reducing the amount of land used per person and the distances people travel.” A resident of Sky City will use 1/100th the average land per person as a regular global resident and will use only 2 tons of CO2 compared to 5.5 per capita.

    I have been following this project and am confused about how many people will be living in it: I have seen 5000 families, 30,000 people and 100,000 listed in various articles. Does anyone know the correct number?

  2. joelbarker June 13, 2013 at 4:55 pm

    I look at the above information and see that 4450 families will live in Sky City, that it will accomodate 100,000 people and that, according to Lloyd Alter, it will hold 30,000. Why these very different numbers?

    Some of the comments are idiotic.
    Why would some residences have no windows? Dumb, from a marketing point of view. A human petri dish? really? This would be no worse and actually better than your average 6 story building. The fresh air is filtered, can be cooled, and heated.
    Dont just read the article people .. learn to dig a little deeper and get more of the story than the blurbs that are reported.

    Now, i too would like it to be a smaller building.. but we’re talking about China here. Billions of people as opposed to 330 million here in the USA. In NYC they already have one large ugly residential tower and are in the process of building another. Think it will have have the tech this building has? NOPE. Will it be self sustaining? NOPE. In other words the community around it will have to absorb the thousand or so people entering and exiting from it each and every day.
    Do i care about Chinas housing bubble? NOPE. Does China care? NOPE. This is really just a test to see how long it takes to put one up and to see if its sustainable.
    First stop is home.. next stop is ???? China has orders… and they are new world ones.

    It will just become another ghost town in the middle of former farm land as speculative overbuilding continues to spread throughout China. This is a really bad idea and waste of resources when millions of empty apartments are on the market with no customers able to afford them and a government that is only concerned with growing their economy. There is a huge real estate bubble in China that’s going to burst very soon.

    Disclaimer: Following is a voice of POSITIVE reason (finally)!

    I would love to live there (if it wasn\\\’t communist) because I\\\’m tired of having to drive back and forth in a town that is so spread out. The way most of us live now wastes so much gas and is so inconvenient, with the rush and traffic and all. Our way of life actually places limits due to these time and resource consuming necessary and daily activities.

    In such a building, EVERYTHING would be within reach within minutes and the ole truck would last sooo much longer. Imagine for a moment (as I have already done so ten years ago) if there was a spiral ramp on the outside that connects to pathways on every level. Then electric mini cars become \\\”the norm\\\” which would then cause the LiFePO4 battery (or better) to be mass produced for cheaper, just like solar panels are about to become. The land below could then be given back to nature and ALL the necessities, such as motocross, sports, gardens, waterways, paint ball, zip lines, whatever!
    This building is just the start (however, doesn\\\’t need to be over 200 levels). I imagine much broader, more stout 3D cities of the future with room for electric car pathways and \\\”yard space\\\” as well.

    Machine automation shall build all the parts (for like everything we need including batteries and solar). Therefore, the OLD malthusian idealism of today\\\’s government employed \\\”environmentalists\\\” (preaching there is not enough resources, etc) is fast becoming just another FLAWED idiotism.

    Such nonsense is, bty, very dangerous because the very thought of \\\”limitation\\\” spawn class warfare in every aspect of the social, from grade school on up to warring countries.

    What I\\\’m trying to say is that \\\”lean and green\\\” will actually become MEAN and green because it will fricking kick ass and I can\\\’t wait!

    Still looks ugly….

    Looks ugly

    Why on earth build such monstrosities? A sitting duck for terrorists. I would never work or live in anything taller than 6 stories high.

    “it could serve as a model for sustainable urban development of the future.”

    It may also serve as the perfect lab environment for facilitating the mutation and spread of disease- the human petri dish.

    i imagine if i lived in one.. i would hardly see the outside world if everything is there..

    it would suck for poeple living deep inside the building with no window views at all…. how would that work
