The term you are looking for is modular home—a house that comes in pieces and is finished on site, though smaller modular homes can be just a single piece. The big difference between the two is modular homes are put on a foundation, whereas manufactured (previously called mobile homes) housing is built on a frame that has temporary axles. If a manufactured house is set on a foundation, it might not be considered a manufactured home anymore. The quality of the build can be good or bad for either type, though cheaper materials tend to get used in manufactured homes since cost is usually the driver on those homes.
