The collection documents projects completed by Casey Coates when she was a student in Parsons School of Design's Environmental Design program between 1972 and 1975. Materials consist of sketches on tracing paper, site plans, land use, climate, and systems studies for three building projects, as well as a silent, color super-8 film capturing street life in Danson's neighborhood on the upper west side of Manhattan.

The collection is comprised of Marty Spiegel's student work for Parsons' Environmental Design Department, which he attended from 1973 to 1976. Consists of course materials, correspondence, drawings and sketches, and printed materials, as well as digital reproductions of 35mm slides of Spiegel's work.

The oral histories comprising this collection were conducted in 2010 in preparation for the exhibit, Radical Shifts: Reshaping the Interior at Parsons, 1955-1985, to record perspectives on the interior and environmental design departments at Parsons School of Design in the 1960s and 1970s. During this period, Parsons' interior design program adopted a more experimental program of study in the newly-created Environmental Design Department.
