Machine-Grown Housing
Eric Harris-Braun writes "Over at Wired, Bruce Sterling has a story about a new way of looking at architecture and building. In fact, computer sculpting of housing is already being done, and non-planned building as an architectural philosphy, is as old as we are, as you can read in The Hand Sculpted House."
This tactic allows him to avoid hidebound European safety regulations when he proposes, for instance, a steel footbridge whose design, sketched using industry-standard CAD software, has been radically distorted by a computer virus. Ask Europeans to cross a buggy footbridge and they'll balk, quail, and consult the 80,000 regulatory pages of the EU's acquis communautaire. Tell them it's art, and they'll flock to it in droves, sit on it, and drink Beaujolais nouveau.
And when it collapses under the weight of that flock...
wtf... this dude is nuts.
*yawn*
Essentially, you build as you need. So if you need a shelf in a certain spot, then you build it there. You can't know everything about how you will use all the space in your house, so the key is to wait until it becomes obvious that something will always be done in a certain way and build to that "spec".
I believe that they did this in UC Berkeley. Instead of building sidewalks, they put some sod on the quad and let the students "create" the trails across the grass. Once the paths were established by thousands of students walking on the grass every day, the school built sidewalks on top of the paths and that is how the sidewalks on the quad at Berkeley were built. No one uses those sidewalks anymore, though, because the grass is so much nicer to walk on than concrete.
So the key is to build as you need, but not to build to the point where you start to avoid the thing you were building it for in the first place.
this is hee-larious. Who would want this?

You'll land in the bathroom/livingroom/spacedock shaped like a booger, and then you can relax in the bedroom/backyard or use your machine-built PC in the garage
I just fail to see how this amorphous abstract thing would be practical. Admittedly, it would be cool looking and unique, but still.
Randomly constructed, on demand buildings. Sounds like the makings of a termite mound....

"Oh, my! We need a coffee maker!"
"Look! The Joneses developed one last month! Let's modify theirs and distribute it throughout the house!"
Some questions arise:
Do I need to raze my old house if I want to change distrobutions?
How many users does that model support?
What kind of designers made the graphical interface; as in: will I want to operate my house from the basement only?
To UGLY and BROKEN houses and buildings. There's a large percentage of

architecture as a human activity that involves creativity and the ability to
solve new problems as they come up.
If you tell me you can help design a bridge or a road with the aid of software,
then i'll buy it, but designing homes (what architecture is about) is way beyond the cold structure design.
Where I live, there's some kind of rivalry (sp?) between architects and what
in my country is referred as a "civil engineer", which is an engineer specialized in structural design and buildings. Both are able to build a house,
but most of the times you can easily spot the difference between a house built
by an architect and a house built by an engineer: Houses built by engineers look "clunky", and while they may be built correctly from a structural point of view, they ocasionally suffer from design flaws such as having bedrooms too close to the kitchen (which means the odor of food being cooked invades other parts of the house). Put simply, the engineer knows about functionality. They
don't know about "aesthetic design". And this is something a computer will never be able to learn either.
There's this joke:
- What's an architect?
- An architect is someone that isn't man enough to be an engineer, but not gay anough to be an interior decorator.
I think the joke sums it up nicely.
but I really don't want to know what architectural philosphy actually is...

Lets just hope that computer doesn't run on Windows. Otherwise the water pipes will leak on your popcorn kernels and overflow the popper.
no offense but essentially every home is built onsite in a custom manner.
Huge portions of home building could be done in large factories, and equally huge strides could be made standarizing the hookups to electricity, communications and plumbing.
i'm not talking about crappy mobiles...i'm talking about the absurdity of custom electrical, plumbing and framing on hundreds of millions of homes.
the endless permits etc...people complain about software but if software were as absurd as home building you would have to get several CDs from various licensed contractors, get a permit from the state to install a computer, have the computer inspected as it is installed and each CD of components is inserted, etc...

Well aren't you behind? I'm living in a modular apartment complex put up by "Cardinal Industries Inc" in 1983.

The two aren't equivalent, so any analogies are going to fail.

Apparently sex is one of those catagories.
thought everyone would like to know that the author of the mentioned book "The Hand Sculpted House", Ianto Evans, has a webpage http://cobcottage.com . Nice guy, cool houses (having been in a few myself), and he does a kick ass slideshow-presentation. My favorite is the $500 dollar house for 2.
He has a fascinating description of a far-future city that has been constructed by machines...and then things go very very wrong...
Best hard-SF/space opera writer out there right now, IMHO.
Freeman Dyson gave a talk in Portland last year. He presented several case studies on how technology planning went right and wrong.
One of the anecdotes was about a research team he was invited to join during the Carter administration. A multidiciplinary team of eggheads got together to come up with ways to make housing cheaper.
They analyzed the factors that made housing expensive, and came up with a list of proposals to make homes cheaper. Factory building components, standardization . . . it all came together nicely.
Before they delivered their findings, they decided to look them over . . . and realized that they'd reinvented the Mobile Home.
I believe that I read about this something like two years ago. It amounts to a 3D printer, but it's using concrete instead of the liquid polymers that stereolith machines do.
This has the potential to drastically cut construction costs, since you can basically eliminate the labor cost of framing the structure. You can even have the robot leave channels in the walls for plumbing, electrical conduit, etc.
Once someone gets around to building an excavation robot to dig foundations and footings, building a house could become a two-man, three-day job (or less).
I hope they get this tech on the market soon. A lot of people could use it yesterday.

This invention isn't about machines doing the designing. The machine allows any design to be sculpted in concrete, subject only to the limitations of the material.

From the article:
I have an old book around here that talks about 1890s Japanese housing, and how certain walls would be removed or replaced in the homes according to need:
What would be a parlour in the day would be divided into sleeping rooms at night.
There is the obvious problem with this: In Western architecture, rooms tend to hold big, bulky objects called furniture. Western culture doesn't tend to sit on tatami mats and sleep on shikibutons.
In our culture, changes to living space tend not to be frequent: We don't convert bedrooms to living rooms daily. When we do want to remodel our homes, we tend to hire builders and remodelers. I suspect that this will be significantly cheaper for quite awhile.
It sounds like he's trying to be innovative for the sake of being innovative.
What a sad, pessimistic world you live in.

I have no problem with your religion until you decide it's reason to deprive others of the truth.
seriously though, i'd like to see tech like this machine-grown housing, combined with the sandbag house or 'old rubber tire' house concepts that have been experimented with, successfully.
.. that'd be an awesome robot worthy of respect, and i for one would welcome its overlord-i-ness ...

With advances in genetic engineering, you can soon grow your own house.
I fear Americans would continue to build Big n' Crappy houses. The reduction in price would mean Bigger n' Crappier houses. Paul Graham mentions this American school of design in his essay.
Maybe some would use the technique to make hobbit-like houses and so on. But we'd see a lot of 5-car garages.

You're nothing; like me.
A: machine automated construction.
I can't get over the way so many allegedly intelligent people cream themselves over these cute 3D animations of a huge behemoth lateral crane picking up building materials and laying them into place and voila, instant house. It must be the Lego lover's mindset, but it's not remotely as practical as it's proponents suggest. (And I still have no evidence that it is "already being done", all I see are drawings. But as Colin Powell proved, artistic drawings are proof of reality. But I digress.)
1. You have to lie these perfectly straight 200-foot rails down at either ends of the lot, perfectly parallel and at a perfect distance. And make sure they don't move.
2. You have to lug this huge behemoth crane on huge supports to the site and *onto the rails*.
3. You have to place all the building materials in perfectly lined up position. Who is going to do this? Construction workers? Another expensive piece of heavy machinery?
4. Who is going to climb up the damn thing when it gets jammed while carrying a 50-foot 10x10 support beam?
B: these wonderful, mod-hippie earthen building materials like cob and superadobe -- all of which are top secret and require you buying book X and going to seminar Q for a hundred here and a hundred there. Nope, that ain't the way to promote an off-the-grid natural building style, that's the way to be a beemer-driving neoliberal. Instead of these wonderfully "grassroots" building techniques going on to revolutionize building and make it accessible to the common man, cob et al become the trademark of upper-middle class SUV drivers who need a way to prove to everyone that they truly are earthy and granola.
(Let's not mention the inconvenient fact that the underprivileged and otherwise construction-disenfranchised that these cheap natural building techniques will supposedly help don't actually *own any land* to BUILD anything on!)
I'd be curious about cob... if it wasn't that every link about it I can find actually tells you *nothing* about how to do it, but instead urges you to attend a fucking paid training session. (And oh yeah, if I were in the landed class.)
I can process rich text, calculate spreadsheets, and read email for free, but I can't build with fucking mud and straw without going to some new age seminar. Funk dat.

A machine that poops out houses. What's next?
This is probably more art than practicality, but The Venus Project has some very cool renditions of automated construction. Check out the "Automated Construction" link on the following gallery:
http://www.thevenusproject.com/vp_gallery.htm
This and other robotic construction techniques are inevitable. The idea of what essentially amounts to InkJet Construction is quite interesting and is certain to take off and evolve.
What is truly interesting to consider, however, are the economic ramifications of this change. Make no mistake, this is as drastic an advancement for construction, architecture and in fact, civilization as can be.
While the switch-over to these techniques may occur slowly at first, once the kinks are worked out of the systems and economies of scale brings the equipment prices down to a reasonable level, automated construction will overwhelm manual construction. It will occur because the resultant structures will be drastically cheaper to build, stronger, more attractive and in all other ways better than hand built structures.
How many people will this put out of work? Consider it for a moment. What percentage of the workforce is construction?
How about real-estate prices? The new structures will be in all ways superior to hand-build structures and can be built in days for the cost of the materials (such as plastic and concrete). Existing structures will loose their values unless they have some historical or other significance, they will be "antiques". Real-Estate prices will evaporate, approaching the price of the lot only (for all one has to do is purchase a lot and hire out one of these machines for a couple of days as competition).
In residential real-estate, people will knock down their own homes and hire out machines to build a better, bigger, custom made one for them.
The implications are astounding.
The reason that it can be true that 1+1 > 2 is that very peculiar nonzero value of the + operator
I can summarize a working minimum of what you need to know about building in cob in one post. That's ridiculously easy compared to brick-and-wood housing!
FYI, here goes:
- Clay, sand, staw. Clay binds, sand prevents shrinking, staw acts as rebar. Use subsoil from the site, tread in the straw. Measure your subsoil by shaking it in water and letting it settle in layers, to see if you need to add clay or sand. Make up test bricks to see if you got the mix right for shrinkage, cracking, and strength. You'll need a higher percentage of sand than you expect. Sieve out rocks and gravel to avoid introducing weak spots.
- Apply it wet enough to squish, neither runny nor hard. Build upwards iteratively, stopping each course just before it starts to sag under its own weight. Measure the plumb with a spirit level and cut off soft cob to keep it from bulging or sagging. Walls can be straight or tapered, which is stronger and saves time/effort building the upper parts. Test taper by gluing a precisely angled bit of wood onto a spirit level. Tapered outside and plumb inside makes furniture an easier fit.
- Overengineer the thickness of the walls. Theoretically, precisely mixed cob applied with skill can be used in walls a foot thick, but build them two feet thick (or more) at the base.
- You need a stem wall, which is a short (waist height) hard and nonporous wall upon which to sit the cob. Stone, concrete or brick are good. This keeps the dried mud above damp ground and rain-runoff splatter. Make the top jagged so the cob sticks. You can skip this, but your house will have a limited "shelf life". Also, the roof needs to overhang enough to throw rain clear of the walls, and you need good drainage and a site which won't flood. In general, water flowing over cob will erode it, but rain won't.
- Cob functions as "thermal mass", bringing inside temperature towards the daily mean temperature (ie: it smooths out cold and heat into continuing warmth). It doesn't insulate much. Avoid using it where you get no sun (north slope) or where the climate is cold all day. Plan the house as a passive solar collector, with windows sited to admit and trap morning and evening sun.
- Joint the cob to woodwork, especially upstairs-floor beams and roof rafters, by burying anchor points of jaggedy wood into the cob wall. Logs stripped of bark with branch-stubs sticking out are good. Don't bury rafters and beams directly into the cob, because they can shift and tear loose due to settlement and heat-expansion. Non-opening window panes can simply be buried straight into walls, with expansion foam around the edges to prevent them being crushed.
- You can build furniture straight from the cob by cantilevering outwards (go slowly) or by carving in. Tamped cob can also be used to make floors - seal the final layer with boiled linseed oil.
- Never put nonporous materials over cob, especially outside. That includes oil based paints, cement based interior and exterior plasters. Cement exterior plaster is a major cause of cob wall collapse. Water runs in through cracks, down the inside and liquefies the wall base. Instead, use mud-straw plaster or lime-sand plaster. Whitewash and casein paints can be used inside and out.
There you go, that's pretty much the beginner's course and adequate if you ignore amenities.
This "technology" is a few millenia old. Sure, maybe it uses different materials and robots instead of people now to lay down the contours, but it's still the same method. And people have built pretty wild shapes out of bricks over the last few thousand years.
Skipping the hi-tech "viab" crap that Sterling focuses on, the appeal here is a return to the less planned, less structured, and more organic process such as the mechanism that grows free software. Wabi-sabi is the formal word for this informal approach and it's been around for centuries. It goes a long way to explain what technology is now discovering.
Here's the Wikipedia link.

As the machines extrude your house, it'll be pretty easy to put in horizonatal wiring & plumbing runs -- just lay them in the damp concrete before putting the next layer on top.
I wonder how they'll handle the vertical runs, like go from the water line up to the kitchen & baths? Also, every building code in the US requires a vent at the top of each plumbing stack, so for every bathroom that's not on top of another bathroom, you need a separate vent.

My memory on some of this is a bit rusty, and maybe I never knew what I was talking about in the first place but it's easier to post than research so....
Early on, the Germans - originators of the modern high-speed road network - learned that drivers get "hypnotised" on long, straight stretches of road so they began to design the autobahn with plenty of sweeping curves and gradients. The topography of much of the countryside helps with this, too.
The US Interstates were built much faster and cheaper, and they have to cross far greater distances than does the autobahn. In the frenzy of "progress", as the American highway network effectively kicked-off the automotive equivalent of what railways had originally done for US economic expansion, efficiency was king (or president, whatever). As a result, the interstates, as much as possible, were built straight.
This has all sorts of knock-on effects. For example, the lack of challenging roads and the need to cross thousands of miles in comfort (at silly slow speeds) led to big, soft, bargemobiles. The Germans are known for building the world's most effective, high-speed, sporting saloons (sedans) because they need them. But don't worry, they're not any smarter than drivers anywhere else. They still manage the kind of suicidal, high-speed tailgating that results in pile-ups of dozens of vehicles.
Unfortunately, the roads and accompanying laws, were designed way back when cars were, frankly, pretty crap. Weak brakes and deadly handling meant that they couldn't exploit these long, flat straight roads to their fullest.
Over the ensuing decades, and especially over the last ten to fifteen years, automotive design has developed to an amazing degree, as has tire technology. If you really know driving, you know that the tire contact patch is your ultimate connection with destiny, so to speak, so improvements in tire technology are quite important.
Road-building technology has also improved in wonderful ways so we can now enjoy road surfaces that are smoother, quieter, stickier AND that do a better job of reducing standing water.
The modern car (and many trucks, for that matter) is an amazing thing. It is faster, safer, quieter, easier, cleaner and cheaper than ever before. In fact, you could argue that it's no longer possible to buy a truly bad new car. Some ain't so hot but they're not bad cars. Not the way we knew them in the '60s, '70s and '80s, that's for sure.
Possibly the only thing that's worse now is the level of road noise as wide, sticky, low-profile tires have grown in popularity and the cars can cruise at higher speeds, the noise generated by the tires on the road is probably higher.
All of this means that, in most parts of the world, the road laws have not kept up with automotive technology and, frankly, we fall asleep at 55mph. The fact is that the 55mph limit was not introduced as a safety measure. So many people, and organisations, go on and on about how we can't raise the US national speed limit because it's safer at 55. The 55mph limit was introduced to reduce fuel consumption during the oil crisis in 1974. It had nothing to do with safety and everything to do with reducing America's ability to be held to ransom by the oil-producing middle-eastern nations.
