It is a little 400 square foot thing outside Moscow that looks quite livable, complete with a little kitchen and bathroom. It was printed by a mobile 3-D printer that extrudes concrete. Doors and windows, electrical wiring and plumbing have to be added by humans by hand. But the printer is capable of extruding the shell of a house in 24 hours for a very affordable cost. With concrete walls, they say that the little house should last for 175 years.

The company that makes the printer is called Apis.cor, located in Moscow, with offices in Irkutsk and San Francisco.

Faintly reminiscent of Edison's prefabricated, monolithic or single-operation concrete housing. Using a complex of sectional molds instead of 3D printer technology to not only cast floors, walls, stairways, tubs and roofs -- and eventually a proposal of even pouring cement mixture into forms for furniture, phonographs, refrigerators, pianos, etc. It was ahead of its time, plagued with initial difficulties, and Edison didn't make complete plans available to builders, so few were ever attempted and built.

A lot of temperature stabilizing thermal mass

This is amazing! I'd live in that..

Here's a video of the printer in action:
