X-SEED 4000: World’s tallest tower will house 1 million people

by Kate

XSeed 4000 Tallest building in the world, Tallest skyscraper in the world will be eco-friendly mountain of a building, Tokyo green building, Taisei Corporation

There’s a lot of debate about what the tallest tower in the world currently is. Some say the Taipei 101, at 1671 ft to the tip of it’s spire, is the world’s tallest tower, whereas we might argue that the Sears Tower, at a whopping 1731 ft (and 110 stories), still takes the prize. However, if the enormous, 13,000 ft X-Seed 4000 structure ever gets built in Tokyo - it will win the worlds-tallest-building competition hands down and leave its puny competitors in the dirt.

Looking eerily like Mt. Doom in the above rendering, the mountain-like X-Seed 4000 represents a utopian eco-vision for a self-contained high-rise city in the Tokyo harbor - powered mainly by solar energy. Aesthetically inspired by nearby Mt. Fuji, the behemoth building would measure 13,123 feet tall with a 6 square-kilometer footprint, and could accommodate five hundred thousand to one million inhabitants.

Designed by Taisei Construction Corporation as an “intelligent building,” the futuristically-named X-Seed 4000 would maintain light, temperature, and air pressure in response to changing external weather conditions.

Unlike conventional skyscrapers, the X-Seed 4000 would be required to actively protect its occupants from considerable air pressure gradations and weather fluctuations along its massive elevation. Its design calls for the use of solar power to maintain internal environmental conditions. Some estimate that the cost to construct the X-Seed 4000 structure may be somewhere between US$300-900 billion.

We’re not saying it’s impossible, but for now, X-Seed 4000 seems like more of a utopian vision for contemporary green urban planning than a viable design solution.

    Sadly like all Japanese supertall proposals, this, Sky City 1000, Mother, The Spiral, TRY-2004, Aeropolis 2001, Hyper Building, Millenium Tower, and several others, will never be built. Japan has a wonderful history of designing architectural vapourware much like South Korea but on an even larger scale.

  2. Bec Says:

    It’s all rather modernist isn’t it. Interesting idea but in a small way it feels slightly robotic. I’d be hesitant living in something powered by solar power if it was life-dependent. A narrow view of course, but whoops a cloudy day and the air pressure is suddenly too much. No thanks. It does look like a man-made Mt Fuji with not an ‘inth of the beauty.

  3. Simon Fodden Says:

    Cool and all. But about existing towers… there’s no debate: the CN Tower in Toronto is the tallest, at a “whopping” 1815 feet: World’s Tallest Towers.

  4. Sea Wolf Says:

    Just exactly what is the point of this? Take a look around at real land, real mountains . . . real earth . . . and you have to say, heck, we’ve already got an excellent planet on which to put a million people, closer to the ground, in human-scaled dwellings. Not suggesting single-family houses for all, just questioning this mega-structure and wondering why it’s on inhabitat. Sustainable isn’t good enough. It also has to be worthwhile.

  5. Peter Goodman Says:

    When I see these proposals I think of the following: smog, a section of the people will often be in clouds and have no way of getting out of them, the massive shadow that the building itself will project over a city, and how big of an eyesore most of these would be.

    Another useful questions is for many of these which have sections that are free-standing and thus can be walked under: what goes under there?

  6. John Says:

    @ Sea Wolf

    These mountians you speak of can only house people on their surfaces (unless you consider drilling into the mountain, and “coring” it but then you run into other issues like the integrity of the mountain (read: cave collapsing)) All in all, actually living on a mountain would do a number of different things.

    First it would piss a whole lot of envorinmentalists off (not saying that building an artifical “mountain” won’t…but perhaps not as much if you consider that it would be built on land that is already colonized for lack of a better word.

    Second, people would only be able to live so high before there is a noticeable air pressure change. Sure, it is still livable people just have to adapt, and this is what defines different cultures, but from a business aspect, no company wants to have to adapt their breathing (permanently for the sake of the argument)

    This man made mountain would serve as a right of passage almost, proving to human beings that we can do large scale things like this, they don’t necessarily need to serve that much of a purpose. Think of concept cars for example, Their only purpose is to stimulate the minds of the engineers so they can produce a cheaper, slower, overall less cool but way more practical vehicle.

  7. jt Says:

    It’s rather elegant looking … however, I sure wouldn’t want to be living in it when a major earthquake strikes!

    You’d think inhabitants of an earthquake prone area such as Tokyo - and where I live - would prefer to be on or close to the ground.

  8. Niko Bellic Says:

    Scary indeed, seems too omniscient like the Tower from Half Life 2 (City 17)..sorta like the eyes of big brother watches you from a top.

  9. Riiiiiiight Says:

    The CN Tower is classified as “The Worlds Tallest Free Standing Structure.” So Mr Fodden, you’re right to say there’s no debate, because the CN Tower does not apply.

  10. Annon201 Says:

    That last picture is of the Shimizu Mega-City Pyramid, not the X-SEED 4000. Also, everyone should check out Extreme Engineering, a documentary by Discovery Channel, each episode covers a different mega-structure and is really interesting despite the fact that the bulidings are probably never going to be built.

  11. G|oS|co Says:

    People people please … one starts with an idea … and works from there … of course there would have to be a need … and of course … a solar outage would not equal catastrophe …

  12. Karin Says:

    I think it is a stunning piece of architecture. It appears to me to be a very lived in shape, think of the pyramids and volcanoes, all teaming with different kinds of life. Very impressive.

  13. Michael Says:

    Once again human kind inspires with the argument ‘that we can’, with little or no recognition of thought given to whether ‘we should…..’

    Seriouly - self sufficiency aside (in the completed mega structure) - how ridiculously HUGE would the embodied energy footprint of something like this be - and how long is the payback period for all that embodied energy???!!!

    I can’t help but agree that we need to be much MUCH smarter in terms of what we benchmark as ’sustainable’.

  14. JAMES GEDDES Says:

    I think it would be feesable if it looked a liitle bit less sinister. The pyramids where very
    sinister, sharp and clean in there original white marble form, back in there day, however
    they where tombs.

    This thing is a residential tower, from what I have read, so, I would soften
    and round off its image a bit more,

    The upper reaches of the structure could also be built in weather protected
    natural materials, like tree trunks.

    The name is a bit too hopefull, but maybe thats appropriate?

    But you will have to have a “HELLISH” amount of ecological ideas,
    and fire protection ideas tested and certified before it would be generally
    accepted.

    What flag would the people doing this put on it ?

    Maybe, a white flag or the united nations flag?

    Good luck.

  15. Mike Says:

    A six square kilometer footprint on Japan’s earthquake pron ground seems to be asking for trouble. Images of the whole building doing the splits as the ground opens up beneath it come to mind.

  16. The Dude Says:

    A gargantuan structure like that will only create a Utopian society that is fully dependent on the environment within the structure itself. Not only that, it will also create a huge gap in society, further creating a divide between the poor and the rich. Of course, only the rich can afford to live inside, and I can imagine a vast city of dilapidated buildings surrounding such huge structure, where the poor lives and they can only get jobs at minimum wages serving the utopian society.

    Just imagine the amount of resources needed to support the population of a structure like that, and just imagine the amount of waste and garbage that will come from it. Even if they say the system is “ECO-FRIENDLY”, these structure will still be the biggest polluters on the planet.

  17. libs0n Says:

    The picture of an enclosed green space is of a “Space Plateau” from the Sky City 1000 proposal. It too has an Extreme Engineering episode devoted to it, and is probably the most feasible of these imaginative concepts; my personal favourite.

  18. Scott F Says:

    Riiiight is right that there’s no debate about the CN tower, but wrong that it “does not apply”. That many do not consider the CN tower a building does not make it any less of a building than the other contenders, which it looks down on. The CN tower IS the worlds tallest building.

  19. Jonas Says:

    Hum, I thought the Burj Dubai is(will be) the tallest? http://www.burjdubai.com/

  20. Cipson Says:

    Looks like the Egyptian Architecture and the pyramids are still in the world with out any problem.

    Dubai may come up with some ideas like this.

  22. Nathan Says:

    Firstly, I don’t understand why anyone would even suggest earthquake issues, considering its being built in Tokyo I’m pretty the issue might have crossed their minds once or twice.

    Secondly, if human kind didn’t aspire to make these types of things, we would still be sitting a fire throwing bones at each other rather than conversing across the internet.

    Thirdly, how exciting! It does have that touch of Metropolis to it

    James I’d say they will put a Japanese flag on it, since it would be built by Japanese people, working for Japanese companies in Tokyo, the capital of Japan. :P

    I guess we haven’l learned very much yet about the “other” aspects of sustainability, like social and spiritual values, or reconnecting with the planet rather than finding ever grander ways to separate further from it.

    This seems to me in many ways to be one more extreme fantasy extending from the early 20th century sci-fi stories (which turm grew out of biblical armageddon and apocolypse stories). Huh? Let me elaborate.

    This way of thinking is based upon a techno-mechanistic storyline which allows an elite group of people to take to the stars while the rest of us poor sods perish with the drained, polluted and war-torn earth…seen in final cataclysm through the rear view mirror of the escaping spacecraft. Got it? We have seen and heard different vairations on the theme for 3 generations now, and when you tell people long enough what the future will hold, they roll over and accept the most astonishing developments as “a given” because they see them as inevitable. Witness Ronald Ray-guns and his Star Wars. And now this. An online community professing interest in promoting sustainable design seriously discussing an artificial community dependent on mecahnical technologies for survival. As if.

    How many people in Tokyo could be better housed in human scaled dwellings for the same expense? How many local businesses could be spun out of that wad of cash, perhaps remanufacturing worthwhile goods from the stream of recyclable materials. Or growing food in city farms? This may not catch as much media attention, but would be a far better legacy for the amount spent. And would go further toward making life in Tokyo sustainable for everyone. As for the need to house ever-increasing numbers of people….. you can buy a lot of infrastructural improvements for that amount of money, and lure residents back to the smaller towns. For that matter, you could produce a massive amount of educational programmes to teach sustainable living skills across Japan.

  30. mgvaughan Says:

    To even consider a project this costly might be an indicator that a government has money to spend. What about poverty, education, science, etc. 900 billion could take care of a gound dwelling society quite nicely. Or… pay for a human colony on Mars.

  41. pawnblue Says:

    Currently, Japan houses about 850 people per square mile. 130 mil over 150,000 sq miles. This building has the potenetial to house 200 times that.

    So as Japan’s population increases, those people can eat up 1200 square miles of Japan. Or they can leave that area alone and green, and pile on top of each other in this thing.

    On top of that, it sounds like they plan to incorporate renewable energy sources. My guess is that the overall impact of a megastructure like this is smaller than sticking a million people elsewhere. I’m not saying their won’t be problems.

  47. DriveBy Says:

    Maybe I’m a bit too cynical, but multiple 30 story skyscrapers hanging from a carbon-fiber tube structure that is sitting on piers in the ocean floor, in an area prone to earthquakes, designed by engineers that probably design to minimum standards, and built by lowest bidder contractors that will no doubt cut corners to make a bigger profit, is not any place that I’d even want to be near, let alone live in.
    It seems that the whole project would be better served by a lower and more solid structure. But that would ruin the whole “Mt. Fuji look” and “taller than you” bragging rights thing, wouldnt it?
    As to the housing of a million people in one structure, Tokyo is probably about the only place that this could be done. Even there, I would think the population density would be pushed higher than many could deal with.
    And then there’s the possibility of fire. Remember the World Trade Center?

I think it is great and all to push engineering to its extremes and design these marvels, but it will be a worry if they start building something like this especially considering the cost.
