Contour Crafting - Extrude-a-House

Posted by michael on from the just-mix-and-pour dept.

lww writes "An article in New Scientist discusses the work of Behrokh Khoshnevis at the University of Southern California to design and build a fully automated robot that performs Contour Crafting, his name for a process to extrude successive layers of semi-fluid building mixtures like concrete to create entire structures. In the article, he says 'The goal is to be able to completely construct a one-story, 2000-square foot home on site, in one day and without using human hands.' by 2005. I'm pretty jazzed at the potential to construct buildings with highly curved/creative contours that would be impossible using current construction techniques."

    The potential is to make them all completely different though. Just feed the robot a different model and you get a different house.

    But what about windows? Having really contoured surfaces dont do so well if you want to put in a window, custom glass costs a boat load....

    Not to mention they make awkward living spaces inside; it just seems that boxes work so much better in house design, although I would love curvature in the corner points in my rooms (a nice, soft, apple-like look).

    Try getting something like this pushed past the trade unions. You might wake up with a horse head under your sheets.

    So it will only take a day to build a house, and with no human hands...but then, you still have to build a big gantry crane over the site, and set up the robot. This thing isn't going to do in-wall plumbing and electricity either. There would still be a LOT of work after the robot did its union minimum.

    This would be nice for a home with no infratructure. How does it tie in to sewer lines, electric grids, etc? This isn't even mentioning teh internal infrastructure - all teh 14guage wiring, the three way switches, the copper feed and pvc drain pipes, etc.

    Also, how does it get all the city bureaucrats on site in one day to do all the

    This sounds like the flying cars we were all promised.

    Sure it's cool that a robot might build a house in a day, but would you really want to live in it?

    Personally, I'd rather have my house built by 100 Amish carpenters over the course of one year.

    I may be a Luddite, in this respect, but I'm also a big believer in TLC.

    It isn't the construction costs so much as the design costs that result in all the houses in a given development being identical (other that rotated 90 degrees, or mirrored).

    The rule of thumb is you should expect to spend 10 percent more if you're having an architect design your house. That means you'd add one percent if you made ten copies of each house. Many of said developments (generically, I call them hives) have only one to five different designs, so I wouldn't say the cost of design is in any way significant.

    The major costs as far as I know are materials, labor, and land. Oh, and profit. Eliminating much of the labor cost would be great, except the price of houses doesn't seem to go down. I suspect what you'd do is increase the cost of one of the other segments (profit, probably).

    Sure would be cool if you could getone of these gizmos from the Rent-All for the weekend and run up a new garage. I hope to see the site if it ever recovers....
