They can also be built to multi-story heights. Motels and other multi-family structures have been built using modular construction techniques. The international communities and acceptance of modular buildings up to (24) floors/stories in Asia.

Exterior wall surfaces can be finalized in the plant production process or in the case of brick/stone veneers field applications may be the builder’s choice. Roof systems also can be apart of - separate from - applied in the field after the basic installation is completed.
