S-Squared submits to Guinness World Records


The S-Squared team believes they may have built the world’s largest on-site 3D-printed home right here in Patchogue.

The cement structure, according to engineer and co-owner Bob Smith, holds about 63,000 PSI, which is about twice the amount of standard cement. Fibers, he said, are implemented to overcome the need for rebar but still, the company is working on formulas and designs to reach peak performance prior to hitting the market.

The homes, he said, can be used in disaster relief, overseas for affordable housing in developing countries, or right here in the U.S. for low-income homes.

The test-run home, built just this month at their location on West Main Street in Patchogue, measured about 500 square feet with 8-foot walls and 12-foot roof. The home, Smith said, was built with the understanding that it must come down, with a low pitch and a temporary roof. 

The cement structure was knocked down and eventually recycled, as was the wood in the roof. It took only about 12 hours to print, plus a little extra time to install the roof. The retail cost would be about $10-$15,000 to build, outfitted with plumbing and electric. Measurements and photos were submitted to Guinness World Records and Wikipedia.

The largest 3D-printed structure, listed on Guinness, is located in China and built in 2016, measuring at about 34 feet by 33 feet and just over 9 feet tall. However, it consists of over 5,000 printed bricks, which were combined. The structure was a model of a 3D-printed Future City, not a home, and made of polylactic acid. 

“The next step is a better design with walls and a bathroom,” Smith said, explaining that they have received permitting to temporarily build a structure in Riverhead for further testing sometime in August. That home, he said, will be larger, about 1,700 square feet including three bedrooms, a bathroom and a garage, which would yield a sale price of about $200,000, fully finished.

Prior to that, the team will be building another 500-square-foot home in Patchogue with more windows, walls and customization. Once the home in Calverton is completed in an estimated 40 to 50 hours, it will be fully finished to look like a standard house. If given a certificate of occupancy and legalized through the Town of Riverhead, S-Squared plans to donate it to a veteran. If not, the permitted home will be used for marketing the product.

According to the Town of Riverhead, the company has approval and an issued permit to print the concrete home on Middle Road in Calverton; however, it is, as of now, solely for the prototype shell with no electric or plumbing. A certificate of occupancy could potentially be issued if and when the home is approved for electric and plumbing and an inspection is conducted.

The company says the cutting-edge technology has the potential to be the next big thing to help improve community infrastructure, with practically zero carbon footprint. By reducing the manpower and resources, the home printer can build a house in a fraction of the time, which reduces the impact on the environment, all while cutting costs and using eco-friendly materials and methods.

Kirk Andersen, engineer and director of operations, said the concept is not to take away jobs, which only required about 10 men to build, but rather increase safety and reduce the cost of housing.

“We are building houses in a really reasonable time, and with customization the opportunities are really limitless,” he said, stating that it’s really up to the costumer to design what they want.

The homes are all printed by S-Squared 3D printers and 4D commercial’s machine/system called ARCS — automatic robotic construction system — which measures 18 feet tall by 32 feet wide. All homes are fire, hurricane, tornado and mold resistant.

In addition to the all the possibilities of 3D printing and with the help of their CEO and operations manager James Michel and media director Constantine Chutis, the company also offers virtual reality tours of the homes that will be built as well as VR experiences of the building process.

A utility patent was filed earlier this year and still in process, and practice printing of home demos will begin this summer at the approved site in Calverton. For more information or to contact S-Squared, visit
