3D-Printed House Gets Permit, Zillow Listing


New York-based construction technology company SQ4D Inc. has listed for sale a 3D-printed home that it says is the first slated to receive a certification of occupancy in the U.S.

The residential property, which was printed onsite with the company’s Autonomous Robotic Construction System, is listed on MLS for sale as new construction for $299,999, in Riverhead, New York.

The 1,400-square-foot home (plus 750-square-foot garage) offers three bedrooms, two bathrooms and features an open floor plan. The building material listed reads as insulated concrete forms and SQ4D notes that the home includes the same 50-year warranty that the company puts on all of its 3D-printed structures.

The ARCS technology reportedly built the footings and foundations as well as the interior and exterior walls and the company notes that it’s a step in its mission to help aid the affordable housing crisis.

"At $299,999, this home is priced 50% 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,” added realtor Stephen King, the agent who has the Zillow listing.

The company reportedly has other plans being reviewed elsewhere in New York as well as California.

3D Printing Tech

Commercial occupancy permits aside, many firms around the world have been stepping into the realm of 3D printing buildings.

At the beginning of 2019, Austin-based Sunconomy, along with San Francisco-based Forge New, were preparing to not only lease their We Print Houses system and technology, but were also gearing up to print what will be the demonstration house for the process moving forward.

At the time, they announced building a house in Lago Vista, Texas, in which the entire structure would be printed. The We Print Houses System reportedly uses hydrophobic, self-binding geopolymer cement that not only complies with international building codes but also meets standards that make the homes safe against most natural disasters.

By December, Boston-based company Apis Cor recently announced that it had completed what it touted as the largest 3D-printed building in the world—in 21 days.

The structure is a two-story administrative governmental office building in Dubai. It was built using just one mobile printer.

The structure is 31 feet tall, covering an area of 6,889 square feet. According to reports, the walls were printed, while other aspects such as insulation, roofing, foundation and windows were installed via traditional methods.

The printing materials was a proprietary mixture of components such as sand, cement and gypsum. The entire cost of the project was not released.

And last year, researchers from the Oak Ridge National Laboratory demonstrated what they are calling a “first-of-its-kind smart wall” that they say combined advanced manufacturing and building innovation during the Department of Energy’s Federal Energy Management Program’s virtual 2020 Energy Exchange.

The prototype wall—dubbed “Empower”—is designed for interior use and demonstrated how a wall assembly could serve as a room’s cooling system and therefore reduce energy use, decrease energy demand, lower utility bills and utilize renewable energy.

The wall, which measures 5-feet by 8-feet, was 3D-printed at the DOE’s Manufacturing Demonstration Facility at ORNL using an infrastructure scale additive manufacturing system called SkyBAAM that prints concrete.
