Swiss architect Peter Zumthor is adding three new buildings to the Fondation Beyeler museum complex in Riehen, Switzerland. The project expands the museum’s ensemble in the gardens outside the existing Fondation Beyeler building, which was originally designed by Renzo Piano and opened in 1997. The additions are planned as a cluster intended to sit within the park setting, complementing the landscape around the museum.
Across outlets, the new structures are described as part of a broader expansion that enlarges and restores the surrounding grounds and increases public access to areas that had previously been private. The three buildings are identified by name as the Wyss Museum, the Ammann Pavilion, and the Erlen Torhaus. Each is differentiated by its function, form, and materials, including descriptions of a rammed-concrete art gallery. ArchDaily also reports that the expansion includes an enlarged park and adaptive reuse elements in addition to the new construction.
Timing details also vary by outlet coverage but align on the project’s staged opening plan: ArchDaily specifies visitor welcome beginning September 26, 2026, with a preview phase through January 14, 2027, followed by a full opening on January 15, 2027.
