Prefab homes, short for prefabricated homes, are residential buildings that are manufactured off-site in sections or modules and then transported to the construction site for assembly. These homes are also commonly referred to as modular homes, factory-built homes, or prefab houses. Prefab homes have gained popularity due to their efficiency, cost-effectiveness, and sustainability.
