Prefabricated House

A prefabricated building, informally a prefab, is a building that is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on-site to form the complete building.Prefabricated units may include doors, stairs, window walls, wall panels, floor panels, roof trusses, room-sized components, and even entire buildings.Prefabricated components are built off-site in a controlled environment, allowing construction and site preparation to be completed concurrently. As a result, the whole building schedule is drastically shortened.
