No. 420 West Broadway (left), ca. 1980. The loft building at 420 West Broadway dates to the 1870s, when it was built for the prominent developer Amos R. Eno by architect Robert Mook. The building was extended to Thompson Street during the 1880s. Until 1970, the building's tenants represented a variety of manufacturing industries, including glass and paper products. After 1970, the building became a locus of the burgeoning downtown art scene, and home to several prominent gallerists. In 2001, the remaining gallerists were displaced, as the building was redeveloped for residential use. Today, marketing materials refer to it as the "Soho Gallery Building."
