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.

Another clip by the Yoshizukis shows the interior of one of the homes, which is spacious, and tastefully outfitted. A Toyota web page provides a few more photos of the interior.

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.”
