The World’s Largest 3D-Printed Community Is Coming to Texas!
Are 3D homes the solution to the housing shortage sweeping America and a way to build sustainably too? One company seems to thinks so and is setting out to prove it: Construction technologies company Icon, a leader in large-scale 3D printing, recently announced a partnership with the home-building company Lennar to build the largest community of 3D-printed homes in the world. Lennar, one of the biggest home builders in the country, is an investor in the Austin-based Icon’s recent $207 million round of financing, and this collaboration brings the two companies closer together.
The project is breaking ground in 2022 in the Austin area and will include 100 single-story homes co-designed by the celebrated architecture firm Bjarke Ingles Group. Icon’s new Austin development will rely on its innovative Vulcan 3D printer. It’s a machine that produces a cement-based mix called Lavacrete. The company says that Vulcan “produces resilient, energy-efficient homes faster than conventional construction methods with less waste and more design freedom— keeping construction projects on schedule and on budget.” These homes can be as large as 3,000 square feet and last as long and even longer than properties that are built using standard construction methods. Lavacrete, according to Icon, combined with other cutting-edge materials can stand up to extreme weather and can help keep the homes intact in the event of a natural disaster.
Icon has already built two dozen 3D-printed homes and structures in the United States and Mexico and claims that this number is the most completed by any construction tech company. Last summer, for example, a homeless man named Tim Shea became the first person to live in a 3D-printed house, which Icon built using Vulcan. The 400-square-foot property is in Community First! Village in Austin, which offers affordable permanent housing to people who are coming out of homelessness.
Innovations in 3D-printed housing could be a game changer for productivity, according to Taylor Marr, the deputy chief economist for the real estate brokerage and research firm Redfin. “The construction industry has lagged behind most other industries in productivity growth—getting more houses from the same number of construction workers,” he says. “Worker shortages have consistently been a challenge for large home builders, and the current labor market has only exacerbated that challenge.”
However, Marr adds that the scale of Icon’s Austin community is small overall in the face of a shortage of five million homes making the housing market increasingly unaffordable. “Nonetheless, it’s a move in the right direction, and, if successful, could be scaled up further across the country,” he says.
