Constructed from 1929 to 1931 as the headquarters for the New York Telephone Company, it is located at the northeast corner of Willoughby and Bridge Streets. It was one of several Art Deco-style telecommunications buildings designed by Ralph Thomas Walker of Voorhees, Gmelin and Walker in the early 20th century. The building was renovated into a residential complex in the mid-2000s.
