Gigon Guyer Architekten is an architectural office based in Zurich, Switzerland, founded in 1989 by Annette Gigon and Mike Guyer, both graduates of ETH Zurich. The firm grew to international prominence with its first project, the Kirchner Museum in Davos, completed in 1992. This launch was followed by several museum commissions, such as the Museum Liner in Appenzell, an extension of the Kunstmuseum Winterthur, the Archaeological Museum and Park Kalkriese in Germany, and two buildings for the Swiss Museum of Transport in Lucerne.
Today, the office comprises around 40 architects and has evolved to tackle a diverse range of building types, including upscale and affordable residential complexes, office towers, mixed-use developments, and cultural centers across Switzerland and abroad. Notable projects include Prime Tower in Zurich, which was the country’s tallest building upon its completion in 2011 and signified the firm’s shift toward large-scale urban developments. Further examples are the Würth Haus Rorschach and the redevelopment of the Löwenbräu-Areal, integrating art, office, and residential spaces.
In 2024, Christian Maggioni and Stefan Thommen joined the leadership, and the firm operates under the name Gigon Guyer Partner Architekten AG. The office frequently wins commissions through competition entries and is distinguished by its careful consideration of context, independent conceptual approaches for each project, and collaborations with artists, especially on color schemes. The work of Gigon Guyer Architekten has been recognized with major awards, including the Fritz Schumacher Prize, RIBA Fellowship, and the Daylight Award.
