A prefab container house, short for prefabricated container house, is a type of modular dwelling constructed using shipping containers that have been modified for residential use. These homes are prefabricated off-site in a factory setting, with the containers being transformed into livable spaces complete with insulation, doors, windows, electrical wiring, and plumbing. The primary advantage of prefab container houses is their efficiency in construction and transportation. Since the majority of the construction work is done in a controlled factory environment, prefab container houses can be assembled quickly on-site, reducing construction time and labor costs. Additionally, shipping containers are standardized and stackable, making them easy to transport to various locations using standard shipping methods like trucks, trains, or ships.
