3D-printed home on Long Island’s North Shore hits the market for $300,000

Just an hour east of the first mass-produced suburb in the United States, a new model of affordable, quick-to-build housing has been realized—and is now for sale—in the town of Riverhead on Long Island’s North Shore.

Boasting three bedrooms, two full bathrooms, and a spacious open floor plan, the suburban New York home in question (asking price: $299,999) is far from your typical, wood-framed affair despite its unassuming-looking appearance complete with traditional siding and a shingled roof. Built with concrete and 3D-printed using the patent-pending Autonomous Robotic Construction System (ARCS) developed by Long Island-based construction technology company SQ4D, the 1,407-square-foot home is the first of its kind to receive a certificate of occupancy and hit the open market via a multiple listing service (MLS) according to the company. While numerous 3D-printed living spaces have been completed in recent years (many featured here on AN), most are diminutive/ADU-sized, experimental in nature, and not necessarily meant for permanent habitation. This isn’t the case with the home at 34 Millbrook Lane, which SQ4D has deemed as the very first “permitted” 3D-printed residence in the U.S. (This claim, however, is somewhat disputable, as pointed out by Gizmodo.)

Situated on a quarter-of-an-acre lot just off of State Route 25 in the hamlet of Calverton, the energy-efficient home, designed by architecture and engineering firm H2M, also features a detached 750-square-foot car garage and a 50-year limited warranty offered by SQ4D for its 3D-printed structures. Most notably, the home’s foundation and interior and exterior walls were all printed on-site using ARCS technology and not fabricated within the controlled environment of an off-site warehouse before being transported to the site, as is often the case with 3D-printed structures.

At $213 per square foot, the home at 34 Millbrook Lane costs roughly half of what newly constructed homes of comparable size built using conventional stick-built methods would go for in Riverhead. As listing agent Stephen King of Realty Connect noted in a press release, the home’s attainable cost “represents a major step towards addressing the affordable housing crisis plaguing Long Island,” particularly on and around the East End.

The home’s hybrid nature required a bulk of it to be fabricated with a massive gantry-style 3D printer situated on rails while the rest of the structure, including its roof, was built using traditional techniques by a small team—overall construction costs were driven down, much of them related to the cost of human labor, which doesn’t come cheap in New York City and environs.

“There is a need to combat all of the rising costs [in home construction],” SQ4d co-founder and director of operations Kirk Andersen recently told the Riverhead News-Review. “Automation is a way to do that.”

With a pair of open houses scheduled for this coming weekend, King, the listing agent, told the News-Review: “My phone has been ringing off the hook.”
