Prior to 1900, there were virtually no playgrounds in North America. As population moved from farms to cities, playgrounds were seen as a way to keep children busy and out of trouble. Since then, both the art and practice of playground design have expanded to include safety, accessibility, and inclusivity, and to encompass and foster child development. Playgrounds have helped earn points for LEED and other certifications, and equipment manufacturers have adopted sustainability programs. This course looks at the architect's and landscape architect's roles in the past, present, and future of playground design and specification.
