Etopia is a company specializing in sustainable construction. It is a one-stop service team made up of the finest young minds at Tongji — not just urban planners but architects, designers, and materials experts. Etopia enables the design of “intelligent sustainable structures,” made either of steel, wood or loam. Not only can these buildings be assembled astonishingly fast, but their constituent parts can be flat-packed and mailed to where they’re needed. Etopia is a private company, but is doing consciousness-raising work typically associated with an NGO.
