Willis and Lillian Leenhouts were a husband and wife team that specialized in single-family residences, and they were well known around the Midwest for their regional modernist style and ability to effectively utilize solar technology in their designs. From the 1940s to the 1980s, the Leenhouts built dozens of projects, and this digital collection from the University of Wisconsin-Milwaukee Libraries presents 80 drawings from 11 of their projects. Visitors can search the collection by keyword, or look through the offerings here by location or building type. The Leenhouts had some rather forward-thinking ideas, and interested parties shouldn't leave the site without looking at their drawings for the Adyar Library in India. All told, the site provides a valuable lens into two important and interesting architects.
