«A ‘masterpiece’ is being renovated,» wrote Hochparterre magazine back in January 2018. The renowned French-speaking Swiss architect and ETH professor Jean Tschumi developed, from 1956 onwards, an open, bright, and functional design that fully integrated industrial materials such as concrete, glass, and aluminium. He also implemented technical innovations such as open-plan offices, a staff restaurant, an underground car park, and active ceiling heating—according to Vaudoise, «all new concepts for Switzerland» at the time.

Second Renovation Required

Despite an initial renovation in the 1990s, the building no longer met today’s requirements in terms of comfort, technology, and energy efficiency. The aim was therefore to preserve the architectural heritage while adapting it to modern standards and new ways of working.

On this basis, an invited architectural competition involving seven firms was held in 2020. The jury selected the project «Un moment charnière» by the Lausanne-based firm Itten+Brechbühl AG. Among other changes, interior walls on the south side were removed or replaced with glass partitions on several floors to improve transparency, natural light, and views.

The color scheme is based on the original palette developed by Jean Tschumi. It helps indicate which floor one is on and where meeting rooms are located. Colors are applied by space rather than by surface area, giving structure to the interiors.

Furniture and Artworks

Following the same logic, the furniture is also an important component of the architectural identity of Le Cèdre. As part of the renovation, Vaudoise has had several pieces originally designed by the architect for the building reproduced. Using archival materials from the company, certain items were recreated as closely as possible to the originals. Adjustments were made only to meet contemporary standards of comfort and sustainability. These re-editions are the subject of an exhibition: Jean Tschumi Designer.

The Vaud-based artist Claudia Comte created a sculpture (Big Cedar Leaf, 2025) as well as a mural in the entrance hall (Sunrise on the Lake, 2025). The sculpture was carved from the trunk of the cedar tree that had fallen in front of the headquarters in 2023.

«In keeping with Jean Tschumi’s vision, the renovated building embodies a vibrant relationship between cultural heritage, architecture, art, and contemporary requirements,» the company stated at the official inauguration.

«Preserving the Spirit»

«It was very important for us to preserve the spirit of Jean Tschumi’s work while adapting it to current challenges. This renovation is a perfect example of our ability to combine heritage and modernity, tradition and innovation,» said Philippe Hebeisen, chairman of the board of Vaudoise Insurance.

«A renovation that preserves the timeless character of a building while adapting to users’ needs is a success,» added Chloé Eckert, heritage conservation officer in the canton of Vaud.
