Pre-fabricated offices are pre-assembled buildings that arrive at your facility fully assembled and ready for immediate use. Modular Buildings are like a big erector set constructed from factory-finished components that are simply assembled. They can be installed as quickly as one day depending on the building’s size and complexity. Pre-fab offices and buildings are ideal for industrial, institutional, or commercial use. Pre-fab offices and buildings are less expensive than traditional construction requiring less time, less money and less manpower to erect.
