To Dream, Perchance to Build


Japan is usually remarkable for its ability to cram lots into tiny spaces, but the most recent architectural unveiling shows they know how to think big as well.

The Taisei Construction Corporation has unveiled some utopian plans for the world’s largest building.

Inhabit writes: “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.”


I doubt that such a monstrosity would be built within our lifetimes, but imagine the penthouse.

    This reminds me of a concept from a Japanese anime called “Ergo Proxy”. The setting is a future Earth in which there has been an environmental catastrophe and humankind have retreated to enclosed cities that protect them from the environment.

    Or perhaps it’s like “Paradise Towers” from the old Doctor Who series.

    Can you imagine living in a building with 1,000,000 other people? From the way the building is described, there could potentially be people who are born in the building and live their entire lives there without ever leaving it. What a concept.

    And yeah… one hell of a penthouse!

    How could they ever build something like that nowadays with terrorism on everyone’s minds? It would make one hell of an explosion when it got bombed.

    “but imagine the penthouse.”

    Penthouse G – as in God – or a villain so dastardly yet stylish not even Ian Fleming and Tom Ford could dream him up.

    Over 300 billion dollars was spent on the Iraq and Afghanistan wars as of last September 2006… if we could just shave a little of that off here and there, we could build this ourselves!

  5. Pepo says

    It’s name sounds like some Mecha Fighter (a.k.a Big Robot with guns) anime. I thought this concept was done a while ago since I saw it on a Discovery channel show, it was a big pyramid back then.

  6. Joe the 'Mo says

    If the cost runs average, 600 Billion (US) and 1 million people live there, the cost would be roughly 600,000 US per person.

    “Sorry Billy-aki, you have to go live with Grandma and Grandpa in Osaka”

    What a phenomenal waste of resources – just like Iraq.
