While he was redefining the boundaries of art in the 1960s, ’70s, and ’80s, Donald Judd reconfigured 101 Spring Street, his New York City home and studio, into a supersized piece of sculpture. Judd, who bought the 1870 cast-iron building in SoHo in 1968 for $68,000, transformed the industrial relic into an architectural version of his iconic boxes. He treated it as a five-story laboratory for displaying art, both his own and that of friends such as Dan Flavin, Frank Stella, and John Chamberlain. In the process, it became a vibrant hub of the art scene that blossomed in SoHo in that era. But as the area changed in recent years from art center to upscale shopping mall, 101 Spring stood suspended in time, a somewhat forlorn reminder of the days before Prada, Banana Republic, and Uniqlo changed the neighborhood.
