The building at 101 Spring Street is one of a few artist homes preserved in New York. As such, it offers a rare glimpse into an artist’s daily process. Judd purchased the building in 1968 after a successful exhibition at the Whitney Museum of American Art. He needed more space than his studio on East 18th street provided, and the cast iron—with its five floors, its open spaces, and its big, wide windows—offered room and light often unavailable in New York. (A few years later, this too would seem confining, and Judd would begin spending part of the year in Marfa, Texas, chosen because of the emptiness surrounding it.) Judd renovated the building along with his then wife, Julie Finch. He smoothed floors and walls, purchased and commissioned art from his friends, and constructed his own furniture. He decided how the building should be used, assigning each floor a specific task: meeting, eating, working, socializing, sleeping. His mark on the space is omnipresent.
