Halprin reopened his office in June 1978 as the Office of Lawrence Halprin. The firm was smaller, thereby allowing for greater intellectual exploration and experimentation. The work from this period incorporated new Postmodernist elements. While Modernism sought to create the perfect form on an empty or open site with a fixed program, Postmodernism embraced wide-ranging social, economic, cultural, and ecological histories of a site and the equally diverse needs of potential users. Projects included plazas, promenades, and park networks, which often grew out of workshops that encouraged broad community involvement and were realized with noted collaborators like architect Charles Moore (Los Angeles Open Space Network) and Israeli landscape architect Shlomo Aronson (Haas Promenade).
