RIVERHEAD, N.Y. -- SQ4D Inc. has listed for sale what is reported to be the first 3D printed house in the United States. This residential property, printed on site using SQ4D's Autonomous Robotic Construction System, is the first 3D printed home to receive a certificate of occupancy and is listed on MLS for sale as new construction for $299,999.

The 3D printed house will feature more than 1,400 square feet of living space, plus a 750 square foot two-and-a-half car garage on a quarter acre. This house includes three bedrooms, two full bathrooms, and features an open floor plan.

SQ4D developed its patent pending ARCS technology to robotically build the footings, foundations, interior and exterior walls on site of their homes. SQ4D will be including a 50-year limited warranty on their 3D printed structures. SQ4D's 3D printing technology can reportedly reduce the cost of new home construction.

Stephen King of Realty Connect, the Zillow Premier agent who has the listing, said, "At $299,999, this home is priced 50 percent below the cost of comparable newly-constructed homes in Riverhead, New York, and represents a major step towards addressing the affordable housing crisis plaguing Long Island."

SQ4D currently has building plans being reviewed from New York to California. See
