One of Zambonini's loft projects from the late 70s/early 80s, the Worth St. loft in Tribeca is also referred to as "Loft 1" in the Progressive Architecture feature on Zambonini's lofts. The Worth St. loft was also the residence of Zambonini and first home of the Open Atelier of Design, prior to the construction of their 29th street offices, studios, and Zambonini apartment.
