George Maciunas consulted with him about architectural matters for 80 Wooster Street and other buildings. In 1971 at the height of the Fluxus movement, Shapiro assisted Maciunas in the production of a Yoko Ono/John Lennon museum show, and he then worked for Lennon and Ono for over a year. Shapiro specializes in the adaptive reuse of buildings and was the architect for the PS1 artist studios and museum in Queens, New York which opened in 1976. The Downtown Collection of the Fales Library at New York University has acquired Shapiro’s personal papers relating to the development of SoHo and the conversion of loft buildings.
