Collectif Xenia is an architecture collective founded in 2022 by Michel Kessler, Pierre Musy, and Romain Iff, three architects based in Zurich and Geneva. The studio focuses on the concept of hospitality and the inclusion of foreigners in its broadest sense. Together, they explore architecture's potential for community building by activating public space through ephemeral, symbolic, and social formats. Their practice ranges from architecture and landscape competitions in Switzerland to international workshops, public rituals, and research-based installations.
Pierre Musy is a Geneva-based architect and videographer. A graduate of ETH Zurich, he has worked with Baukunst and BUREAU, and co-curated the independent art space BELLA. His film Desert of the Real was presented at the Lugano Territorial Biennial (2022).
