Our long time client Céline Baumann got a guest professorship at ETH Zurich, the Architecture Department, D-Arch. In fall 2023 her seminar, at ETH Zurich called studio, was about how rhizomatic structures may allow us to act upon broad territories in order to shape ecological and climatic corridors for humans and non-humans alike. Apart from developing the visual profile we coded a little program, which creates the imagery for the poster series: a rhizhome as an ever growing structure. The topic for the spring semester 2024 is Concrete Garden. The students will investigate the qualities and potential of this spontaneous urban nature, a topic that has seen renewed interest in recent years.
