This is topped with a two-story copper fronted mansard roof, now coated with verdigris, reminiscent of Parisian architecture.The New York City Landmarks Preservation Commission, in its 1973 report on the SoHo-Cast Iron Historic District, says the building, at 495 Broadway, was designed by Alfred Zucker for Augustus D. Juilliard and was completed in 1893.Several other sources shown below say the building was designed by Buchman & Deisler for Jeremiah C. Lyons, who had previously developed real estate in other areas of Manhattan, and was completed in 1897.It burned for two hours before being noticed and causing the partial collapse of eight floors[9] toward the rear, or Mercer Street side, of the building.The collapse was caused when three unprotected hollow cast iron support columns 14-inch (36 cm) in diameter buckled because of excessive heat, bringing down the eight stories above.
