We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
In time, these houses won't be as ugly and more will be able to be produced in shorter periods of time. I'd expect these innovations to be available soon, too. Say three to five years. Affordable homes are much needed here in the U.S. I expect some entrepreneur here will figure out how to make that work very soon.
Perhaps that is a good portion of the cost. House behind me ran $400,000 to put up. Sold, eventually, for $1.4mm (other costs incurred, of course. Purchase was $400,000. Not sure how much the other payoffs were, if any. Taxes were significant, though I have no idea what they were.
Point is, $5,000 to just build and 10 in one day? There's a huge profit waiting for someone who is creative enough.
They remind me of the houses made from prefabbed concrete that where going to be the big thing 50+ years ago, the modular homes of 30 years ago etc. While commerical construction is quick to pick up on things, zoning boards etc are not when its residential.
I agree that it's coming but disagree that it will reduce prices any. The machine will require a very level building site to work in, the transportation and set up won't be free and the maintenance won't be cheap. Because it will have to use low slump concrete it will be slow and concrete isn't cheap either.
Even with conventional framing or block walls the exterior walls go up pretty fast and cheap anyway, it's everything else that takes so long and cost so much.
I used to build 2 story houses on 9' pilings. We set 18 piles, framed, sided, installed windows and doors, roof and shingles and 2 sets of stairs in 6 days with 6 guys. The rest of the house took 3 or 4 months to finish.
