Change of owner, management and name change

To our clients and business friends

We are happy to inform you about the succession of Wiederkehr Antosch Architekten.


Last year Wolfgang Antosch acquired the ownership shares of the co-owner and partner Alphons Wiederkehr.


From 1 January 2023 he will be responsible for the entrepreneurial orientation of the company and its presence on the market under the new company name Antosch Architekten.


The competent management consists of Wolfgang Antosch as owner and the experienced members Anne Dürkes and Urs Balmer who have been part of our executive team for several years. Alphons Wiederkehr will continue to support the office in areas of project development and consulting.


We as the new executive management are grateful and very motivated, together with our qualified staff, to lead our successful company into the future with a new structure, yet proven principles and company-specific values.


We are very pleased to continue working for you, thank you for your trust and wish you a happy, successful and healthy New Year.
