The Clean Hub, “a new prototype for sustainable infrastructure” conceived by Shelter Architecture in collaboration with Architecture for Humanity, and designed and built by architecture students from the University of Minnesota, is a breath of fresh air in an often-luxury prefab world. One of the finalists in American Express’ Members Project (vote for the Clean Hub here!), the freestanding module delivers completely off-the-grid infrastructure, from clean water and sanitation to renewable power to disaster areas or rural locations without access to such resources.
