Architecture, Building and Structure Design Prototype for Temporary Sales Pavilion by OPEN Architecture OPEN conceived a prototype V1.0 of standard temporary sales pavilion that enables speedy construction, can be adaptable to different programs and sites, and more importantly, dissembled after each use and reassembled at another location. The structural skeleton, the composite floor panels and the façade system, are all devised from one modular system, and prefabricated off site. This re-useable building is an experiment to test the ultimate potential of sustainability, not only in its realized physical form, but also the meaning in its life cycles.
