Abstract: The present invention relates to a system for constructing temporary prefabricated structures for the motion picture, television and stage play industries. The invention uses interchangeable panels with an array of connecting elements for constructing walls, roofs and floors. Because of this nature of interchangeability, flexibility in the use of our panels affords last minute changes in set design to accommodate desirable camera or actor movements. The materials used are substantially strong enough to withstand transportation, use in adverse weather conditions, and storage for reuse, and are recyclable when life expectancy is reached. The system does not require site preparation prior to assembling structures. Buildings can be erected on virtually any surface and over existing vegetation with out destruction. More particularly, the components used to erect the structure are easy to assemble and disassemble and do not require the use of any fasteners or tools or heavy construction equipment.
