3D-Printed-Houses-21Disposable housing will blindside the real estate industry
in virtually every country on earth

When it comes to doing something first, and winning the technology race, there are typically no official forms to fill out, no rulebooks, no judges, and certainly no deadlines.

In fact, when it came to using 3D printers to print an entire house, a process known as contour crafting, only a small number of people actually knew how important this race really was.

During the past few years, I watched as several groups worked feverishly to have their names emblazoned in the annuls of history, but I was surprised when an unknown company in Shanghai, China claimed victory using an alternative approach I hadn’t even considered.

While other groups were preparing to print their houses on location, the Chinese team came up with a modular approach, printing all of the components inside a large factory, and transporting and assembling the houses at their final destination.

With this approach, the WinSun Decoration Design Engineering Company not only printed a house in a day, they completed 10 houses in a single day using a massive printer that was 490 feet long, 33 feet wide, and 20 feet deep.

The ‘ink’ used was made of recycled construction materials, industrial waste and tailings, and according to Architect’s Newspaper, each of these homes cost around $4,800.

No, they’re not ornate mansions with lots of decorative trim. Some would even say they’re ugly. But they represent the first of an entirely new wave of housing – inexpensive, durable home that can be produced in only a few hours for very little money. This process is perfect for fabricating homes for the poor and homeless, a major issue in China, as well as virtually every other nation on earth.

Ugly or not, WinSun won the first phase of this undeclared competition, and is now putting together plans to build 100 factories in China to “collect and transform” construction waste into aggregate for its machines.

The most important feature, at least in my mind, is that these houses can just as easily be ground up a second, third, or fourth time, and be reprinted as an entirely new home. They are, in fact, disposable houses that will fit very well with the nomadic lifestyles of future generations.

Here’s why this will be such a massively disruptive technology.

In a recent interview, WinSun’s CEO Ma Yihe said that he has been working on this concept for the past 10 years, and his company currently owns 77 national patents on construction materials, such as fiber reinforced gypsum and special fiber glass cement.

The houses were not the first buildings printed though. WinSun also printed its own headquarters building, a 10,000 sq meter facility that was printed a few months earlier and took 30 days to create.

Like other 3D printers, WinSun’s contour crafting machine carefully extrudes its fast-drying material one layer at a time.

Even though some view this as a somewhat sloppy process with rough uneven surfaces, the end result is a textured wall with its own brand of character.

Future Houses

The houses built in China are in stark contrast to a project going on in Amsterdam, where a crew has begun work on a project that aims to print an entire 13 room house, including some of the furniture—all in one fell swoop. The timetable is three years and the finished product will likely wind up costing millions.

The thinking in China is that with a little refinement, future houses may be printed in less than an hour, reducing labor costs to almost nothing.

With a little engineering work, everything from fixtures, cabinetry, plumbing, electricity, and heating/air conditioning can be modularized and rapidly installed into houses much like the Plug-n-Play hardware systems of the of the PC era.

Ductwork, plumbing, and wiring channels can be printed into the structure, and adding water, power, and heaters may become as easy as working with Legos.

As part of the re-printing process, houses will be demolished, chipped, and ground to a predetermined particle size, encapsulated in some bonding agent or concrete, and augured into a 3D fabricator, and layered into the final structure.

The Permanency Dilemma

A team of research engineers at the University of Wisconsin in Milwaukee has developed “100-year concrete,” a new water-repellant concrete mix, which they claim will hold up with little or no maintenance for well over a century.

The 100-year concrete was created by adding superhydrophobic elements that prevent the normally porous concrete from absorbing water and developing cracks.

As an extra feature, unwoven polyvinyl alcohol fibers were added to let the concrete bend without breaking. The end result is a super durable form of concrete able to withstand four times the compression of traditional concrete.

The question then becomes one of permanence. Should houses be built to last 100+ years, or with contour crafting technology, and our ability to reprint houses in less than a day, will an expected lifespan of 10-20 year be sufficient, or even preferable?

Here are a few reasons why having a disposable mindset may beneficial when it comes to real estate.

  • When moving across town, or to a new city, it makes much more sense to reprint a home in the neighborhood you want than to settle for what available.
  • Housing needs change as people move through different stages in life. Families with small kids need a different house than those with teens, and once kids move out, it changes again.
  • Whenever wind or hailstorms cause roof damage, it may be easier and cheaper to reprint a house than to repair it.
  • People who work from home can easily add an office or two when needed.
  • In places where flooding, fires, shifting soil, or termites cause major damage to buildings, the entire architecture can be reworked to compensate for those problems.
  • As people get older and no longer want to do steps, two story houses can be turned into ranch homes.
  • When driverless cars make owning cars obsolete, garages can be eliminated and reformed into other kinds of usable spaces.

Entering the Disposable Housing Era 

When reprinting does become viable on a broad scale, we will go through a messy transition period.

While we will be able to eliminate poorly constructed buildings and houses that have haunted cities for decades, we will also see many conflicts over radically designed houses being printed next to classic mansions.

Real estate values will begin to fluctuate wildly. Scarcity and lot premiums will become far less significant.

Realtors will likely morph from the heavily regulated sale of real estate to sellers of the transformative lifestyle changes that accompany a reprinted home.

Apartments and condos will become far more difficult to rent as printed homes undercut the price of rental units.

The rules for home mortgages will have to be rewritten time and time again to mesh with changing attitudes and shifting cultural norms. This will cause no small amount of upheaval in capital markets.

As houses are printed with non-flammable materials, there will no longer be a need for fire insurance. Once houses can be reprinted for less than the cost of re-roofing them today, we may eliminate the need for house insurance altogether.

Once we are able to remove the transaction costs from housing, our populations become infinitely more fluid. A fluid population is a fickle one, often moving on a whim, rather than the long drawn out process that it is today.

City populations will expand and contract in dramatic fashion, often reflecting people’s changing attitudes associated with political decisions, local elections, increased criminal activity, changing tax rates, and much more.

Where would you live if moving was easy?

Final Thoughts

Rest assured, the disposable housing trend is not about to kick in just yet. But it may be far sooner than most people think.

Printing 10 houses in a day is already compressing the building process 100-fold. If we are also able to eliminate many of the rules, regulations, hearings, insurance, mortgages, and planning processes, we may approach 1,000-fold efficiency improvement.

That will be the equivalent of jumping from pony express to smart phones with nothing in between.

So far we’re just scratching the surface. The rest of the disposable housing revolution will follow shortly.

    Well, what comes next? I wonder how long it will be before they can 3D print an rv, for example? What if, as a result, RVs became much less expensive and much more popular, and,with telecommuting and such, we turned into a society of nomads?

      David, You are correct, but just hitting the tip of the iceberg. Over time 3D printers will be used to print massive vehicles and structures ranging from ships, to airplanes, to stadiums, to floating islands. Thomas Frey

    Although this looks like it will impact negatively the housing / building / mortgage industry there will always be people who want a more tradionally built home. However as a solution for areas that require low enviromental impact and quick production for displaced people of anykind... (think refugess, shanti towns, victims of huricanes and floods etc nnd then there is the attractive cost....WOW! One downside I wonder about...findng enough non toxic materials to make them ???

      Jewels, Some good points. Whenever there is a new trend, it means means that relatively more people are doing something new and relatively fewer people are doing what they've always done. So yes, there will be many still building traditional homes. I don't think the lack of materials will be an issue anytime soon. In fact, I've seen a dirt compression technology that could be even faster and cheaper than 3D printing houses. Tom

    The only way this hugely disruptive technology will become viable is IF the profits margins/ROIs are so irresistable that existing rules and regs are willingly and dramatically altered. A viable air car has been around for several decades now and the only reason YOU don't own one is purely POLITICAL. Air car technology is so disruptive to the current economic paradigm that the PTB basically refuse to address or produce rules and regs that would allow it's widespread adoption. This is the same reason we're still forced to buy cars that use a 100 year old propulsion technology. Bottom line: if there's not rapacious profits to replace current cash flow paradigms then it's DOA. Furthermore let me assure you there's little profit incentive in low income housing.

    Is it not the land cost that is the main problem? Maybe skyscraper contour crafting will make a bigger difference, people could have large apartments rather than coffin boxes due to the reduction in the use of land and therefore cost.

    Funny how some think they can see the future when they can’t yet see the land. There’s already fast, cheap housing — rammed earth, straw bale, etc — even free housing in places like Detroit and the rest of the Rust Belt. What a 3D printer can not fabricate is a location, and that is the stumbling block to affordable housing. How do you make locations or land affordable? Counter-intuitively, you tax them or otherwise collect their rental value for public benefit. Levying a tax or deed fee or land dues removes the value of the land from the mortgage and puts it into the public treasury. Thus mortgages for buildings become far more affordable. And poor people are already paying the value of their location in the monthly apartment rent that they pay. Choosing to build on a cheap location is no solution, either. As other people follow suit, the price goes up. That’s what happens in every city where the hip, artistic young people congregate in a certain neighborhood. Once its reputation gets established, its site values skyrocket. And all the hip people are back to square one. No, there really is no way to avoid paying for land. The best that people can do is pay each other. That is, pay land dues in and get rent dividends back. More at Progress.org.

    Think of the early adaptors for this product. I'd try to find locations where construction waste and cheap housing are most in need.
  7. <a href='http://Futuristspeaker.com' rel='external nofollow' class='url'>Steve Poppitz</a>

    excuse me...I meant where construction waste was most AVAILABLE and VERY cheap housing was most needed. Poor third world people (for example) will "settle for what's available", now match it where construction waste is readily available and hopefully free.

    We as a society are trying to find ways to build faster, smarter, "Greener" and more profitable. I doubt this concept will eliminate modern building practices but is a fabulous solution to house the homeless and less fortunate. The first is will it create profits. Corporations left behind will use lobbyist to squish the idea.
