90 Fifth Avenue, ca. 1914. Designed by 1902 by Robert Maynicke, the loft building was one of a number commercial building constructed on Fifth Avenue by the Cooper Union-educated architect. The eleven-story, cast-iron building with classical details included 140,000 square feet of space. In the 1980s the large industrial building was gutted and converted into the headquarters for the Research Institute of America. Forbes became a longterm tenant in the 1990s (leaving in 2013), and today the 3rd through the 11th floor is home to the brokerage company, Compass.
