A prefabricated house, often referred to as a prefab home or modular home, is a dwelling that is manufactured off-site in a controlled factory environment. The components of the house, such as walls, floors, and roof structures, are prefabricated and then transported to the final building site for assembly. Prefabricated houses are known for their efficiency, as they can be constructed faster and with less waste compared to traditional on-site construction. These homes come in various styles and sizes and can be customized to meet specific design and functional requirements.
