While prefab abodes and tiny homes are on a trendy upswing, a new exhibition in France shows how the concepts are far from new. On display at the Friche de l’Escalette sculpture and architecture park in Marseille, France, Plastic Utopia features three iconic prefab micro-dwellings from the 1960s, fully outfitted with plastic furniture from designers like Maurice Calka, Quasar Khanh, and Wendell Castle.
