The benefit of portable buildings is the flexibility they provide. They can be quickly and easily transported to and around worksites. Their versatility makes them useful to a variety of industries, as pop-up cafes and art spaces, or sheds, garages and accommodations. The tradeoff for their portability can be a lack of robust construction and security features.
