Collaborative Constructions investigates a new practice of architecture based on the creative, innovative and personal use of technology. The two projects by our chair at ETH Zurich and the University of Tokyo engage in a global collaboration looking at architectural strategies to relate nature and humanity through technology; they are results of human-robots collaborations and exemplify how we can engage with the past while looking ahead.

Our contribution consists of a three-storey tall timber-frame structure, which revives the long history of expert timber construction in Japan through Swiss design and technology. It revisits carpentry for the age of robotics, making metal parts, nails, screws or fasteners obsolete. The five constituting timber frame modules consist of more than a thousand bespoke timber elements and were prefabricated in the dRobotic Fabrication Laboratory at ETH Zurich. Designed to withstand earthquakes and storms, the towering structure activates its surrounding neighbourhood and landscape, while the wooden terrace or Japanese engawa serves as a meeting point for the community. Age-old knowledge has been revived through digital technologies, allowing for a highly material efficient and performative approach to building with timber. A new strategy for building multi-storey timber buildings is thus suggested as a sustainable alternative to conventional concrete and steel constructions.
