Lying on the intersection between art and architecture, the Berlin artist duo Franz Hoefner and Harry Sachs create site-specific temporary architecture, innovative performances and constructive interference in the urban environment. The book Hoefner/Sachs documents and illustrates their subversive projects in detail for the first time. Among the projects featured are miniature bee-cities positioned next to prefab buildings, and tongue-in-cheek mounting of laminate, panels and woodchip as a means of upgrading the cityscape.
