Modular is one of the most complete types of prefab housing. Modules or boxes are built in the factory, and wrapped and taken by a flat-bed truck to the construction site. One or many modules are lifted by a crane and set on a foundation. Some modular homes are almost complete when they arrive at the site with siding, kitchen appliances, flooring, and so on; others need a good deal of work to complete at the site. In areas where labor is very expensive, completing more of the work in a factory in a less costly labor area is a fiscal benefit to the owner.

Panelized construction is another popular type of prefab method. All of the exterior walls are installed on site like a jigsaw puzzle. Some panelized homes arrive on site with windows and doors installed and others have those parts installed on-site. Whether the components arrive with siding and roofing and other aspects can vary with each manufacturer and each home.

Structural Insulated Panels (SIPs) are another form of panelized construction. These are panels that generally have two oriented strand boards (OSB) that are fused with a type of insulating foam in the center. The boards are “locked” together and structural without the need for wood framing, which can be a vehicle for air infiltration. SIPs are extremely energy efficient, are installed very quickly, and require fewer interior walls, which creates a very open interior area.

Kit houses go back to the old days when people bought houses in a catalog (think Sears houses), and they were shipped by train to the house site. However, kit houses today are far more sophisticated, efficient, and elaborate. All of the components for the house are built in the factory, numbered, and shipped to the site. Lindal Cedar Homes, a kit manufacturer in Washington State, ships their homes around the Unites States and around the world, including to Canada and Japan.

In addition to the above categories, there are also other types of prefab construction such as log homes, light and heavy steel frame construction, container homes, several types of prefabricated concrete homes and combinations of the various methods.
