Connect Homes builds its sleek, modern, green homes in a factory in Mesa, Arizona and ships them worldwide. Nearly everything gets done in the factory -- interior, exterior finishes, doors, windows, fire sprinkler systems, roofing, plumbing, electrical and mechanical. This means that there are only module-to-module connections left to be done on site. The system allows Connect Homes to sell beautiful, steel-frame modern homes for a lot less than they'd cost otherwise.
