Peter Zumthor's Expansion Harmonizes with Fondation Beyeler's Landscape
In Riehen, Switzerland, the Fondation Beyeler museum has undergone a significant expansion, spearheaded by the renowned Swiss architect Peter Zumthor. This ambitious project introduces a collection of new structures deliberately designed to integrate harmoniously with the existing park environment. Zumthor's approach prioritizes a gentle assimilation of architecture into nature, ensuring the new additions feel like an organic extension of the landscape rather than stark interventions.
Situated within the verdant grounds surrounding the original Fondation Beyeler, which was conceived by Renzo Piano in 1997, the recent additions comprise three distinct buildings. These include an art gallery constructed from rammed concrete, a cultural venue encased in glass, and an office facility distinguished by its timber cladding. Rather than consolidating these various functions into a single monolithic structure, Zumthor's studio, Atelier Peter Zumthor, opted for a decentralized arrangement across the museum's expansive parkland. This thoughtful scattering of buildings facilitates a deeper integration with the natural surroundings, making each structure appear as if it has always been an intrinsic part of the site.
Zumthor articulated his design philosophy, expressing a desire for the new constructions to blend so effortlessly that their presence would feel inherently natural. He noted with satisfaction how visitors perceive these buildings as if they have always been there, a testament to his successful integration strategy. From an external perspective, the buildings gracefully complement the site's topography, while their interiors boast spacious, unconstrained volumes that exude expressive beauty without conforming to rigid formulas.
The Wyss Museum, a three-story edifice, features a distinctive Y-shaped floor plan meticulously crafted to circumvent existing trees, thereby preserving the park's natural arboreal landscape. Its exhibition spaces are endowed with expansive windows that offer captivating vistas of the surrounding foliage, blurring the lines between inside and outside. The museum's walls are fashioned from rammed concrete, enriched with Jura limestone aggregate, which imparts a warm, yellow hue to the facades. This local Jura limestone is also incorporated into the building's terrazzo flooring, as well as its solid stone staircase and seating elements, further grounding the structure in its regional context.
Adjacent to the Wyss Museum is the Ammann Pavilion, a single-story building envisioned as a communal lounge and a versatile venue for cultural gatherings. This includes a spectrum of events such as performances, lectures, and film screenings. Its walls, crafted from glass set within oak frames, immerse the interior in the surrounding park's ambiance. Cherry and pear wood surfaces introduce warmth to the internal spaces, which are characterized by stepped flooring that ingeniously doubles as auditorium seating, enhancing its adaptability for various events.
The Erlen Torhaus building houses art logistics facilities and administrative offices. An underground passage connects it to the existing museum, streamlining operations. The ground floor, dedicated to processing art deliveries, is elegantly clad in varnished oak, while the upper-level workspaces are distinguished by large windows that frame views of the park. As part of the broader expansion of Fondation Beyeler, Atelier Peter Zumthor collaborated with Vogt Landscape Architects to refine the park's landscaping. This collaboration included the strategic placement of outdoor artworks by celebrated artists such as Louise Bourgeois, Pierre Huyghe, Rachel Whiteread, and Fujiko Nakaya, further enriching the visitor experience.
Beyond Zumthor's new trio of buildings, existing structures within the museum complex have also undergone restoration and repurposing. The Orangerie building, for instance, was transformed by French architect India Mahdavi into a greenhouse complete with an adjoining shop for plant enthusiasts. This renovation unveiled the original timber roof structure and introduced subtle light-green accents, refreshing the space while honoring its history. Swiss firm Forsberg Architekten revitalized the museum's Ammann Atelier, converting it into art education and workshop areas, and also created a music listening lounge in the adjacent Salon room. The expanded Fondation Beyeler initially opened with limited visitation on September 26th, with a full public inauguration scheduled for January 15th, 2027.
