After winning the competition to build the new Zuger Kantonalbank, Leo Hafner (1924-2015) and Alfons Wiederkehr (1915-1985) founded their architecture firm in 1948. Following Alfons Wiederkehr's death in 1985, his sons Alphons and Rolf, together with Leo Hafner and Georg Krummenacher, continued to run the office under the name Hafner + Wiederkehr + Partner Architects. Leo Hafner took his retirement in 1994, after which his partners took on the responsibility for the practice that followed – Wiederkehr Krummenacher Architects. Rolf Wiederkehr and Georg Krummenacher stopped working in 2019, and Wolfgang Antosch became a partner. Together with Alphons Wiederkehr, Wolfgang Antosch now heads up the newly established office of Wiederkehr Antosch Architects. As a long-standing employee, Felix Möller also became a member of the management team until his retirement.
After taking over the ownership shares of Alphons Wiederkehr, Wolfgang Antosch is responsible for the entrepreneurial orientation of the company and its presence on the market under the new company name Antosch Architekten from 1 January 2023. Together with him as owner, Anne Dürkes and Urs Balmer form the competent executive management. They are motivated, together with a qualified team of employees, to lead the successful company into the future with a new structure, yet proven principles and company-specific values.
