Can We Beat the Housing Crisis By 3D-Printing Homes? (msn.com) 160

"As housing prices across the country continue to skyrocket, an Iowa-based company, Alquist 3D, is looking to combat the crisis by 3D-printing homes," reports NexStar Media: Alquist, one of a few U.S. companies that 3D-prints houses, is looking to build 200 of these homes in Virginia starting this summer.

The process is somewhat simple. First, a person designs what they want the frame of the house to look like by using a computer program. Then, a file is transmitted to a machine, which tells it what to do and how to move. On-site workers pour in cement material, then the concrete is pumped through the tubes and dispersed in layers...

Zachary Mannheimer, founder and CEO of Alquist 3D, believes 3D-printing is a game changer because it cuts costs up to 15% by scaling back labor, materials, and time. He does understand that there are concerns about displacing traditional construction jobs, and some environmental impacts of this method, but he says he is working to attack those issues.

  • The housing market is widely believed to be in a bubble. Give it until this massive recession hits in a year or so and you will see home prices drop instead of increase.

      Not really. The housing market is short 1-3 million new homes. While rising interest rates may affect it slightly. The reality is mortgage interest rates diverged from federal rates a decade ago and the two have nothing to do with each other now.

      Same with credit card rates. You used to be a good payer they would lower your rate. Now they just give you more credit while mainting the rate.

      A decade of stupdily low rates has screwed up all the bubble calculations. Doesnt mean bubbles arent forming. However the talk and fear of bubbles forming will keep them from doing much.

Further, I clicked on the top 3 rental results, and all were sold in the last 6 months prior to becoming rentals.

        While the second half of your post is quite relevant this first half is not. A large portion of the rise of rentals is due to the impossibility of actually owning a house. When people can't afford a house it stands to reason that there would be a large rental market instead as it is the short term cheaper and more available option.

          The short list of 'for sale' means they don't last on the market before being bought. Having more rentals available on the market does not mean that people are renting because of the home ownership, it means that properties aren't finding tenants as quickly as homes are seeing purchases.

      Also buy-to-let (not sure what you call it in the US, people buying property to rent it out as a source of income).

      People wanting to actually live in those homes are at a disadvantage. They need a mortgage, and the bank has to agree with the valuation of the property. Much easier to sell to a cash buyer who will rent it out, or who can get a much smaller mortgage with the rental income used to justify the valuation.

    • Zoning and infrastructure is likely the limiting factor.

      I'd add land prices. It's great to cut construction costs 15%, but if land costs are a significant part of the price then that will not make much of a dent in availability. Once an area has little available land to build on it becomes the limiting feature. What would likely happen, if someone built such homes and sold them for less than the going rate is people would snatch them up and resale prices would rise to their actual value based on comparables.

    The way to beat the housing crisis is to allow more housing. The problem isn't technological but regulatory. It is incredibly hard to build more housing in the US. Zoning restrictions along with strict building codes make it extremely difficult to build new housing or build new housing at any reasonable density. People love the Boston style Brownstones for example, but it is illegal throughout Boston and its suburbs to build anything that dense now. And in some places, NIMBY groups oppose even the smallest of constructions. And this is impacting not just housing. In New York City, due to the floor-area ratio rules https://www.planning.org/pas/reports/report111.htm [planning.org] it is impossible to build new skyscrapers unless the surrounding area has very short buildings. This sort of anti-building, anti-growth attitude is also causing large-scale environmental harm, like how in Maine, NIMBY groups blocked the construction of new electric lines to move hydroelectric power from Canada into New England. In many different respects, the US is systematically not allowing people to build like we used to build. It isn't a coincidence that many other parts of the world don't have these problems. For example, Japan has much denser housing in many places and yet housing remains cheaper there.

      The UK actually has enough housing. It's just that a lot of it is in areas where there are few opportunities and little work, and much of it is in a state of disrepair. Most houses have poor energy efficiency. The new ones being built are low quality and overpriced.

    Putting up the walls is only 10% of the effort of a build. The other 90% is the foundation, wiring, plumbing, drainage, damp course, insulation, roof, render, windows, plasterboard, lights, fittings etc. In addition 3d printing kind of sucks the higher up you go - there is a reason most demonstrations of it are only single story buildings.

    So no, 3d printing won't solve a housing crisis. It might be slightly faster than (some) forms of construction but it's not some panacea or solution to housing problems. In fact to solve such a crisis it would probably be relieved by some proper urban planning - high density units like flats, condos & high rises instead of a sprawl of suburban properties.

    • There is also a question of how durable in the long term the 3D-printed house components are. When it comes to any construction work, compressive strenght and tensile strenght of used materials are a critical factor, and a new manufacturing technology may mean a completely different distribution of forces inside a component, affecting the durability as well as safety of the building.

    3D printing is exciting technology, but for building homes it does not live up to the hype IMHO. Take a closer look at so-called 3D-printed houses, and you'll see that with today's technology, 3D printing only covers what is called framing in conventional construction in a typical North American home - and it doesn't even include floors. Just the core of the upright walls, nothing else gets 3D printed. Everything else is still conventional: foundation, floors, roof structure and shingles, inside wall finish, siding, windows, doors, flooring or carpeting, plumbing, showers and bathtubs, lighting, electricals, kitchens, heating and air conditioning ducting and controls. And what is 3D printed, is done in concrete, with plenty of heat bridges on the inside. This may provide better insulation than walls of poured concrete, but it's difficult to get to the excellent insulation of a modern wood-framed wall. Not to mention that wood is a carbon sink, whereas concrete has a big carbon footprint because of the way cement is produced.

    In the UK at least, the main cost of a house is the land, regardless of what you build on it. Land in sought-after locations is more expensive than land in less popular locations. The cost of actually constructing a house has relatively little effect on the price of the house.

    There is the problem that because land is generally an appreciating asset, it often pays developers to own land, but not develop it. This is termed "land banking". Similar things happen when a developer builds an apartment or office block, then leaves it empty, because it earns money anyway, even without any tenants paying rent. If you rent the property out, you then incur maintenance costs. I believe there is quite a lot of expensive property in London like that.

    The main political problem with tackling house price inflation is that existing home owners treat their homes as financial assets, so any attempt to drive down house prices generally will be met with fierce resistance. In addition, many home owners have borrowed heavily to finance their purchase, so a falling asset price would leave them with a debt that is increasingly difficult to service. I imagine falling house prices would make mortgage lenders nervous, because of reduced security. If the lender did decide to foreclose, they would not get their money back.

    Though there is regulatory pressure to coerce developers to build affordable housing, along with more expensive neighbourhoods, there is a fear among existing residents that this might drive down property prices in the area, so they don't want it where they are.

  • so where are you going to build this

  • There is no housing crisis. For example, in California, the official shortfall in housing units is approximately equal to the number of illegal aliens in the state.

    Meanwhile, regulatory requirements are a huge burden on the cost of a house, up to 20-30%, and legislators keep adding more burdens, not to mention property taxes that have to be paid in addition to mortgages.

    And simple 3D printing costs are misleading.

    Yeah, you can print the SHELL of a building.}

    Insulation, wiring, plumbing, glazing, weatherproofing, etc? That's where the real costs lie.

The truth of a proposition has nothing to do with its credibility. And vice versa.
