In October 2021, the fourth extension of the Kunsthaus Zürich opens on Zurich's Heimplatz. At this time, preceded by twenty years of planning, the building is falling out of time: a luxurious concrete repository for private collections with no connection to its immediate surroundings, sealing the entire site and disallowing any participation from the public, neither in its appearance nor in its programming. The repetitive limestone curtain that envelops the building reinforces the monumental character of its size, a costly expression of existing power relations. The physical inertia finds its counterpart in the institution's lack of transparency in handling its controversies.(Cf. Ep. Kontamination) Bauen im Neubau begins immediately after the building's supposed completion and reclaims the unfulfilled promise of publicness. (Cf. Ep. Aglaia)
