Engineers and manufacturers have been working to automate the homebuilding process for years, and some startups have already released prototypes of their designs. Until this year, however, nobody has lived in any of these prototypes.

This summer, a five-person family in France became the first to permanently live in a 3D-printed home. The 1,022-square-foot home, part of the "Yhnova" project, is located in Nantes.

Below, take a look at the building's construction process and photos of other startups' designs for 3D-printed homes.
