Founded in 1961, Koch Hazard Architects is an Architecture, Interior Design, and Planning firm, located in Sioux Falls, South Dakota. Although the majority of our work can be found throughout Eastern South Dakota, we have significant experience in designing for the broader region at large. Since our inception some 60 years ago, every project has been characterized by an exacting and deliberate level of thoughtfulness. In the tradition of our office’s founders, we endeavor to exhaustively study the implications of our design in order to ensure its contribution to a positive and functional user-experience. A building which does not improve the lives of its users, is not worth building.
