History
Stephanie Wellnitz now leads the architectural firm founded by her grandfather, Carl Müller, in Offenbach am Main in 1930. Today, the firm is in its fourth generation, and since January 2025, Nina Delius has joined as a partner.
Respect and understanding for the location and existing buildings have been the central concern for over 90 years, along with a commitment to contemporary, durable, and economical architecture.
Following the tradition of predecessors Carl Müller (grandfather), Wolfgang Müller (uncle), and Fritz Wellnitz (father), the needs of the clients and users are always the top priority.
