A 3D-printed house destined to radically shake up building costs goes on sale

You’ve probably heard of 3D-printed face masks and even 3D-printed hands, as 3D printing technology has expanded over the past few decades.Now a company says it has listed the first 3D-printed house in the US for sale. The Riverhead, New York, home is listed online through Zillow with an asking price of US$299,999 ($390,987).”This is the future, there is no doubt about it,” Kirk Andersen, the director of operations at SQ4D Inc, says.

SQ4D uses automated building methods, or 3D printing, to build structures and homes.”What we want to do is print homes fast, and cheap and strong,” Mr Andersen said.The company can set up its Autonomous Robotic Construction System at a build site in six to eight hours.

It then lays concrete layer by layer, creating footing, the foundation of a house and the interior and exterior walls of the structure.

“It’s a radical change for job sites,” Mr Andersen said.3D-printed houses could also end up having a radical effect on the wallets of potential buyers in America.”The cost of construction is 50 per cent cheaper than the cost of comparable newly-constructed homes in Riverhead, New York, and 10 times faster,” Stephen King, the Zillow Premier agent who has the 3D house listing, said.

The 3D-printed house will include 1407 square feet of living space and will be built with concrete.The home has three bedrooms, two baths and a 2.5-car detached garage.”I want people to not be afraid of automation … it is just a different tool and different method. But it’s still the same product; we are still building a house at the end of the day,” Mr Andersen says.An open house, held for the 3D home on Saturday, featured the company’s already built demo home.

Mr Andersen and Mr King say the Riverhead home is the first 3D-printed home to receive a certificate of occupancy in the US.That wasn’t easy because of strict local building codes, they said.”We did it in one of the hardest places and there’s a beauty in that because that means we can eventually do it anywhere,” Mr Andersen said.”We can make things more affordable and safer.”We can use the technology to tackle homelessness, and aid in disaster relief in an eco-friendly way.”
