In a tiny village on the outskirts of Nacajuca, Mexico, builders are creating new homes using an oversize 3-D printer.
Pop-up temporary cabins, 3-D-printed buildings: whether such super-cheap housing is a good idea or not, it’s probably the wave of the future because we are so far behind providing shelter for all. Typhoons, floods, entrenched poverty, opioid devastation. All require new solutions to homelessness.
First, let’s take a look at 3-D homes in Mexico.
Debra Kamin reports at the New York Times, “Pedro García Hernández, 48, is a carpenter in the southeastern Mexican state of Tabasco, a rainforest-shrouded region of the country where about half of the residents live below the poverty line.
“He ekes out a living making about 2,500 pesos ($125.17) a month from a tiny workspace inside the home he shares with his wife, Patrona, and their daughter, Yareli. The home has dirt floors, and during Tabasco’s long rainy season, it’s prone to flooding. Dust from his construction projects coats nearly everything in the home, clinging to the bedroom walls, the pump toilet and the counters of his makeshift kitchen.
“But that will soon change. In a matter of months, Mr. Hernández and his family are moving to a new home on the outskirts of Nacajuca, Mexico: a sleek, 500-square-foot building with two bedrooms, a finished kitchen and bath, and indoor plumbing. What’s most unusual about the home is that it was made with an 11-foot-tall three-dimensional printer. …
“And now, the era of the 3-D printed community has arrived. Mr. Hernández’s home is one of 500 being built by New Story, a San Francisco nonprofit organization focused on providing housing solutions to communities in extreme poverty, in partnership with Échale, a social housing production company in Mexico, and Icon, a construction technology company in Austin, Texas.
“When New Story broke ground on the village in 2019, it was called the world’s first community of 3-D printed homes. Two years and a pandemic later, 200 homes either are under construction or have been completed, 10 of which were printed on site by Icon’s Vulcan II printer. Plans for roads, a soccer field, a school, a market and a library are in the works.
“Single-family homes are a good testing ground for the durability of 3-D printed construction because they are small and offer a repetitive design process without much height, said Henry D’Esposito, who leads construction research at JLL, a commercial real estate firm.
They can also be constructed to tolerate natural disasters: Nacajuca sits in a seismic zone, and the homes there have already withstood a magnitude 7.4 earthquake. …
“ ‘We know that being able to build more quickly, without sacrificing quality, is something that we have to make huge leaps on if we’re going to even make a dent on the issue of housing in our lifetime,’ said Brett Hagler, New Story’s chief executive and one of four founders.
“The organization was started in 2015, shortly after Mr. Hagler took a trip to Haiti and saw families still living in tents years after the 2010 earthquake there. Across the globe, 1.6 billion people live with inadequate housing, according to Habitat for Humanity. …
“Speed is only one factor in bringing a village to completion — New Story has teamed up with local officials in Tabasco to bring sewage services, electricity and water to the community.
“Mr. Hernández, who has plans to expand his construction business to a larger space in his new home, said he was not focused on a move-in date. He cares about the long-term impact the home will have for his daughter, who is studying to become a nurse.
“ ‘When we receive the house, my daughter will be able to rely on it,’ he said. ‘She won’t have to worry anymore.’ ”
Meanwhile in Boston, construction crews have been working on a pop-up, temporary community to relieve the pressure at a trouble spot known locally as Mass and Cass.
Milton J. Valencia reports at the Boston Globe, “The crews had already built new pop-up cabins over the last two weeks. And on this day, they were digging through concrete to connect to water and sewer lines, putting the finishing touches on a new, makeshift cottage community to house people who are homeless.
“The pop-up community — which could be fully operational by Monday — is just one piece of what state and city officials hope will be the solution to a sprawling tent encampment at the intersection of Massachusetts Avenue and Melnea Cass Boulevard, what has become the epicenter of the region’s opioid crisis.

“Seventeen sleeping cabins, ranging in size from 64 to 100 square feet, are lined up in two rows. At one end is a courtyard. And at the front of the village is a 500-square-foot structure that will serve as a common room, where those living there can gather for meals or counseling. Other services — to help treat addiction or mental illness — will be available at the site. And at the end of the day, those living there can retire to their own personal sleeping space. …
“As city officials and social workers push people to leave their tent encampments near the Mass. and Cass intersection, they invite them to the new cottage community, marketing it as a temporary but appealing option that could serve as a warmer, safer transition to long-term housing.”
Will there, in fact, be safer, long-term housing? That is the question.

I read, a few weeks ago, about a printed home of large size, having taken over a year to build, out of molded cement, in The Netherlands, I believe (somewhere in northern Europe). It’s hoped that that process, once refined, will lower the cost of housing. Must find that article again!
I’ve read that cement (concrete?) is both good and bad for ending climate change. *Nature* mag: “concrete has a colossal carbon footprint — at least 8% of global emissions caused by humans come from the cement industry alone”!
Hmm, I’ve also heard that there are ways to recycle cement.
[…] Printing Out a Home […]
I’d worry that the “Mass and Cass” encampment will become the “Mess and Cess” site if the incoming residents remain unemployable addicts, which so many of the homeless campers are here in California.
OK. Good line, Earle. At least the mayor is not ignoring the problem.
I hope my sister sees this and is interested. She is an architect, and she and her husband were part owners of a home building company in Boulder Colorado. They built out several subdivisions, and a recent fire there may create a huge market for quick home replacements.
Oh, that was a terrible fire. My friend’s niece has part of the area in her state gov district, so I’ve heard a little that way.
