This series holds items documenting Zambonini’s architecture and interior design projects from the late 1970s until the end of his life, in both a personal capacity and while at the OAD. Organized by individual projects, this series consists primarily of drawings, sketches, plans and blueprints of the projects, as well as photographs and slides of building sites and completed buildings and interior design work. Materials pertaining to Zambonini's design of the OAD offices and upstairs apartment on West 29th St. in NYC are found in the OAD series.
