A robot can print this $32,000 house in as few as eight hours

Building a house completely by hand can be both time-consuming and expensive. A number of home-builders have chosen to automate part of the construction process (i.e. by printing the home's parts) instead.

A new Ukrainian homebuilding startup called Passivdom uses a 3D-printing robot that can print parts for tiny houses. The machine can print the walls, roof, and floor of Passivdom's 380-square-foot model in about eight hours. The windows, doors, plumbing, and electrical systems are then added by a human worker.

When complete, the homes are completely autonomous and mobile, meaning they don't need to connect to external electrical and plumbing systems. Solar energy is stored in a battery connected to the houses, and water is collected and filtered from humidity in the air (or you can pour water into the system yourself). The houses also feature an independent sewage system.

Passivdom's homes, which start at $31,900, are now available for pre-order online in the Ukraine and the US, and the first ones will be delivered later this year. 

Check out the homes below.

Passivdom is not the only company using 3D-printing to build homes. The San Francisco-based housing startup Apis Cor, Dus Architects in Amsterdam, as well as Branch Technology from Chattanooga, Tennessee say they can construct homes in mere days or weeks.
