Constructing a house from lumber and drywall can take months or even years—but in Japan, Toyota is erecting entire homes from pre-built segments faster than some people build Ikea furniture. A video of the process shows workers using a crane to drop room-sized units into place like Master Builders in The Lego Movie.
According to husband-and-wife vlogger duo Rachel and Jun Yoshizuki, who filmed the construction process and uploaded it to YouTube, the prefab units are built in a factory and trucked out to an assembly location. The entire construction process, they say, is only 24 hours—though it takes a few more days to round the whole house out with electricity, flooring and paint on the walls.
The segments of the home appear to each be about the size of a room, complete with electrical fixtures, windows and closets. The video shows workers bolting the segments together to form a house, attaching siding, and even adding a second-story deck as a finishing touch.
There are few references to Toyota's prefab houses in the English-speaking media. According to a book about construction engineering published earlier this year by two German scholars, each room of the modular Toyota home is made up a steel skeleton, which provides structure, and interior components like appliances and furniture, which are called "infill."
