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

by , 08/20/07

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.

    Meh the world trade centre was not designed for what happened to it, alas innocence lost, modern buildings take it into account, secondly as fantastic as this design is, it is never actually meant to be built certainly not as is, it was a completed design created to gain recognition from the architect\\\’s and was no seeking of backing or running it via government was involved.

    If a project like it is ever created it will be after the success of a project like tokyo sky city, probably some considerable time after as given the time it\\\’s taken to get to a km up (as in not happened yet, though one is definitely on its way http://en.wikipedia.org/wiki/Madinat_al-Hareer and after the km\\\’s up getting km + buildings as archology style structure such as the Sky city 1000, will require some serious interest though given japan\\\’s interest and frankly need it it may well get of the ground, before anyone would consider such a considerable leap due to the obvious conservatism of the world as demonstrated in this very set of comments,

    Not just one most likely several sky city size and larger projects are likely to go first so by the time projects such as this may be seriously considered the population density will have probably increased to the point where it is seriously needed and would represent a distinct improvement to those who like have green in the countryside and like a countryside period instead of eating them up with possible future super-city sprawl\\\’s another 20th century sci-fi concept, one that if population increased can only be prevented as a necessity with projects like this, and will provide the average person with more space.

    Basically for now its merely a future theory impressive to look at but not even the designers intended this to be real, look at sky city for something more likely to happen within the next 30 years, given mile high towers going up it\\\’s getting easier to sell the concept on the \\\”don\\\’t get left behind\\\” bandwagon as well as obvious necessities

    additionally to the chaps who clearly know nothing about it, building lots of cheap low-land housing would wipe away the countryside and ultimately have a far more detrimental effect to the environment then one highly efficient building and 1 million people will use 1 millions people worth of resources when not in one place building by concentrating them it is possible to reach far greater hight\\\’s of efficiency then all the homes requirs to house them conventionally and frankly all the equipment required will allow efficiency by bulk if you truly wish to help earth\\\’s future environment you have to look outside the box and arcologies represent a valid solution, socially speaking, each one will be a city in its own right, and no doubt act like one

    Frankly i for one would be pleased city where one is unlikely to have to encounter far less petty thieves, petty drug dealers and other petty crime due to none of them being able to afford to go there, instead of a unattainable idea if they have any sense the poor will view it as a great place worth of working their way out of poverty providing an impetuous for improving self-change and hopefully to boot a few less criminal\\\’s will realise what they can\\\’t attain by that way of life and go straight out of it to, of course all that social bit is idealist nonsense based on the preconception the average person is at his heart \\\”nice\\\” but nevertheless if they had any sense, it would be true, and that means at least some that do will be inspired, such a building looming down on one can\\\’t help but remind them there\\\’s bigger things and greater achievements waiting to be had out there then their petty real life issues, and provide incentive for the next generation of thinkers and innovator\\\’s as every great work and innovation of the past has, and it would be a an achievement worth of praise.

    i believe in higher thinking, in a higher order of things. this, if done, will be the ultimate habitat for what earth would be like in future days. Our salvation from the destruction on earth, the pioneer engineering marvel that would initiate more x-seeds to come per nation, per island, per society. muwah to cuteness, to love!

  4. LEGEND June 20, 2008 at 7:07 am

    OFF course its a brilliant idea………..but yes its true that JAPAN AND SOUTH KOREA have made a habbit of making wonderfull designs but with no sign of taking any steps towards making them…..BEFORE this i thought THE SKY CITY was the best…..but this one is really mind boggling I LIKED it but i seriously doubt that this project will be completed soon……….its more like a TIME MACHINE……where people know how to make it BUT DONT KNOW WHEN TO MAKE IT OR HOW TO MAKE IT…….i think probably 50 years will be needed to complete this mamoth project……with the best technology available may be it ll take 40 years but having the BUDGET in mind really will hault the process of constructing this building …….I DONT THINK JAPAN CAN AFFORD THIS PROJECT…………..but yes we doo need few project like this one cuz as the day pass by we do need new spaces for the growing population of EARTH and project like this will significantly reduce poppulation as well as pollution………SAaeO NARA………..AU REVOIR !!!!!

    To be Creative has no end actually, I personelly appreciate the design as this is a creation and inventive attempt to get something new in the field of urban planning else than repeating and modifying the existing ones and acheiving rewards over the other practices.
    Hands up for this inventive approach.
    Thanks

  7. Crackito January 19, 2008 at 9:25 am

    What is the objective of imagining the construction of such a building of enormous proportions to it’s surrounding landscape, other than to imagine? Is it the desire of the architect to fulfill his ego with a building it’s equal? Althoug an excellent use of imagination, it’s far from the mark of being sustainable or progressive… Mostly powered by solar power, it is barely worth mentioning with the amount of materials and energy that would be required! 1 million people in a 6km sq footprint… What land would provide for this population? Where does their waste go? What social benefits comes from an encapsulated community, that must be supported by it’s exterior…? Can it be pictured that these types of structures would pop up and become our skyline to compete with a range of mountains? I sincerely hope not… Grand as it is, dull it is in fact, an unchanging, unrealised poor attempt at mimicking a natural structure that should be revered as a metaphoric hurdle to overcome or reach the top of. Something that is constanatly transforming landscape and inspiring us to live in coexistence rather than competition, that grounds us and maintains humility. GREAT ASPIRATIONS!

  8. Scott E January 9, 2008 at 8:54 am

    I believe it is a great idea, the sheer size of this building in todays standards may overwhelm the smaller structures it dwarfs but with solar panels and such you could keep a large population within that space and keep them happy. to shun ideas like this seems rather primative, where would we be today if it wern’t for these weird, wacky ideas, for instance…. man on the moon “this is one large step for man, on giant leap for mankind.” gotta take the steps and leaps sometimes to move ahead. plus you are saving space by having larger structures taking up un-used skyline space. pretty sure these things will have there own presurised invironments in the future.

  9. Scott Houdek(Orion105) December 28, 2007 at 11:18 am

    imagine having a nose bleed!!!!!!!!!!!!!!!!!!!!!!!!!!!!, well anyway, the idea having structures is INCREDIBLE does apply, one looks at this structure from the inside, it hit you between the eyes, (sort of speak), it reminds me of the movie in United States that is called: “Star Trek – The Wrath of Khan” showing what will the future look like, unless some unforeseen event such as a nuclear war or a meteoric strikes, a alien invasion!!!!!!!!!!!!!!!!!!, the sad part this enormous ideas that is done over seas, that old phrase “not in my back yard” has to be stopped because of “PROGRESS”, if someone can put a man on the Moon, this is the way to do it!!!!!!!!!!!!!!!!!!!!!!!!!.
    I am sick and tired of seeing buildings being blown down by a tornado or a hurricane, because of our primitive of thinking(the HUMAN BRAIN) and man power and way too much politics and sooooooooo much GREED.
    that stifles progress in the making, if “we” don’t move our rear ends, we just as well live like the “Flintstones” forever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  12. Eric Norcross December 26, 2007 at 1:03 pm

    In reply to some of the concerns posted here, if you didn’t notice, there is no facade in the design of the building, it is meant to be a skeletal structure for the purpose of ‘not’ casting a shadow over Tokyo. This is the same concept of the Time Warner Center in New York, whereas rather than building one tall structure and casting an afternoon shadow over the park, they, instead, built a reflective two towers to enhance the sunlight during the afternoon.

    I’m positive the other concerns are being dealt with as well, would any architectural engineers care to comment?

    C.N tower is not a building for the last time. the word building is derived in in skyscrapers as something that is occupiable throughout (i.e. each floor) and not a concrete shaft housing an elevator to a few storets of resteraunts and observation decks

    This sheds light on the least discussed issue of planning and economics, Population Growth Management.

    The US will have 400 million people soon, Russia held a National Copulation Day two weeks ago to “thwart” their population “shortage,” China recently revised its child bearing policies, not to mention the explosive growth in Central and South Americas.

    The issue really is about habitat and controlling our propensities for “growth.”

    And DriveBy, of course, is guilty of assuming the rest of the world is enthralled by the lowest possible price.

    American myopia. Amusing if it weren’t so tragic.

  48. Sasha August 24, 2007 at 8:07 am

    well, like many others i am wondering what is the point/need to build a 4000 meters tall residence? How safe would you be on a top floor in a case of emergency/fire? even if you run it may take you an hour to get out. will air travel be safe? 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.

  54. DriveBy August 22, 2007 at 1:33 pm

    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?

    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.

    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.

    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

    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.

    Did you see the Rotating sky scrapper ??

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

    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.

    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.

    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.

    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.

  87. JAMES GEDDES August 20, 2007 at 10:27 pm

    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.

    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’.

  89. Karin August 20, 2007 at 9:20 pm

    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.

  90. G|oS|co August 20, 2007 at 8:47 pm

    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 …

  91. Annon201 August 20, 2007 at 8:40 pm

    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.

  92. Riiiiiiight August 20, 2007 at 8:31 pm

    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.

  93. Niko Bellic August 20, 2007 at 8:20 pm

    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.

  94. jt August 20, 2007 at 8:16 pm

    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.

  95. John August 20, 2007 at 5:50 pm

    @ 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.

  96. Peter Goodman August 20, 2007 at 5:48 pm

    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?

  97. Sea Wolf August 20, 2007 at 10:43 am

    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.

  98. Simon Fodden August 20, 2007 at 10:24 am

    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.

  99. Bec August 20, 2007 at 8:58 am

    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.

    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.
