With her site-specific interventions, the artist Karin Sander intervenes in the structures of spaces and institutions, changes them, re-contextualizes them and calls for their participatory appropriation. In this monographic publication, the artist does the same with ARCH+ and develops a connection between the pages of the magazine and the wall as a constitutive artistic and space-forming element. Karin Sander's work group "kitchen pieces" (from 2012) plays a central role here and is published extensively for the first time in this context. The monograph also reflects on her contribution "Neighbors", conceived together with Philip Ursprung for the Swiss Pavilion at the Venice Architecture Biennale in 2023, which literally dissolved the dividing wall to the neighboring pavilion. As an outlook, the publication explores the changing status of the wall, which is transformed into data in the 3D scan-based working methods and research of the artist and her chair at ETH Zurich.
