+ 19

The Fondation Beyeler in Riehen, Switzerland, is expanding its museum ensemble with three new buildings by Swiss architect Peter Zumthor, an enlarged and restored park, and the adaptive reuse of several historic structures. The expansion extends the existing museum designed by Renzo Piano, adding exhibition, education, cultural, and public spaces while opening a previously private section of the surrounding landscape to visitors. The expanded ensemble will begin welcoming visitors on September 26, 2026, during a preview phase running through January 14, 2027, before fully opening on January 15. Zumthor's additions comprise the Wyss Museum, the Ammann Pavilion, and the Erlen Torhaus, positioned within the existing landscape and differentiated through their programmes, forms, and material treatments.

The Fondation Beyeler in Riehen, near Basel, will begin opening its expanded campus to the public this autumn, with the full ensemble set to be accessible in January 2027. The project brings together the museum building designed by Renzo Piano Building Workshop and opened in 1997 with a series of new additions by Peter Zumthor, as well as several repurposed historic structures. Through the expansion, the institution increases its exhibition capacity while extending its grounds to include a larger public landscape. The development represents a new phase for the Fondation Beyeler, building on its focus on the relationship between art, architecture, and nature.

In 1979, just a year after founding their practice, Herzog & de Meuron won a competition to design a public swimming pool for the Swiss municipality of Riehen. After developing several unrealized iterations over the following years, the project was put on hold indefinitely in 1982. Twenty-five years later, in 2007, Herzog & de Meuron were commissioned to rethink the project and proposed to abandon the conventional pool concept with its mechanical and chemical water treatment systems in favor of a pool closer to natural condition with biological filtration.
