Modular buildings and modular homes are prefabricated buildings or houses that consist of repeated sections called modules. "Modular" is a construction method that involves constructing sections away from the building site, then delivering them to the intended site. Installation of the prefabricated sections is completed on site. Prefabricated sections are sometimes placed using a crane. The modules can be placed side-by-side, end-to-end, or stacked, allowing a variety of configurations and styles. After placement the modules are joined together using inter-module connections, also known as inter-connections. The inter-connections tie the individual modules together to form the overall building structure.Modular buildings, also called prefabricated homes or precision built homes, are built to equal or higher standards as traditionally built homes. The building method is referred to as permanent modular construction. Material for traditionally built and modular homes are the same. Modular homes are not doublewides or mobile homes.
