100 Gold Street, ca. 1921. When completed in 1920, the Hide and Leather building had the distinction of being the tallest concrete building in the world. Constructed by the Hide and Leather Realty Company, an association of merchants in that trade, the 17-story building was designed by the firm of Starrett & Van Vleck. The firm was best known for designing a series of department stores, including the flagship stores of Lord & Taylor, Bloomingdales, Saks Fifth Avenue, Abraham & Straus, and Alexander's. A mix of offices, showrooms, and lofts the building was demolished in the mid 1960s as part of the Civic Center urban renewal project. It was replaced in 1969 with the nine-story Tishman Downtown Center Building. Though the new building could hardly be called a skyscraper, as its predecessor was when completed in 1920, it is none the less considerable in size, with each floor covering more than an acre and a half.
