STEVE STIMMEL, AIA
Steve, as an architect retired from active practice, volunteers for the Iowa Architectural Foundation to advocate for design and historic preservation through public education. By guiding tours, researching and delivering presentations, and serving on local committees and boards, he continues to discover new information to share while enjoying personal relationships with colleagues and participants.
Steve’s interest in modernist architecture and historic preservation began as a student at Iowa State University in the late 1960s designing class projects while working part time at the University of Iowa when architects of national reputation were transforming the campus. Parallel to experiencing modernist creativity, Steve formed his personal historic preservation ethic, influenced by the observation of the loss of historic resources to urban renewal and relationships with pioneers in the Iowa historic preservation movement.
Following graduation, Steve’s career at two Iowa design firms was highlighted by the opportunity to work in Des Moines for BBS Architects | Engineers, the descendent firm of Proudfoot and Bird who began Iowa practice in 1895. A career highlight was working with the owner-design-construction team for the rehabilitation of the Mies van der Rohe designed Home Federal Savings and Loan Association building for the Diocese of Des Moines, which received the Commercial Design Award of Excellence from Docomomo US in 2019.
