Compared to a mud hut or shanty made of cola flats or tin cans, which is probably what the new owner was living in the day before, it probably looks like Gracie Mansion. Try not to look at it through first-world eyes. These are aimed at poor Chinese peasant families, not your sub-development. When 3-D printed homes come to America (and they will) they probably won't look like these.
Don’t worry. The process will become much more sophisticated in a pretty short period of time. Just remember the first cars, airplanes, and computers, and compare those to what is available now. And with the design power we have it suspect it won’t take fifty years or so to get there.
