The document discusses the increasing frequency and severity of natural disasters like floods, earthquakes, and cyclones. It argues that in the face of more frequent calamities, there is a need for more sustainable design thinking during disasters to help communities recover and rebuild. Specifically, it presents a design for a "Liv-in cube" constructed from shipping containers that could be used as temporary or permanent housing after disasters to provide shelter in a cost-effective and customizable way. It provides a breakdown of the estimated costs to construct a single 20-foot Liv-in cube.
