It was built in 1888–1889 by William C. Schermerhorn on the site of the Schermerhorn mansion, and rented by him to a boys' clothing manufacturer. The Romanesque Revival loft building was designed by Henry Hardenbergh, architect of the Plaza Hotel and The Dakota. The building is constructed of brownstone, sandstone, terra-cotta and wood, and has dwarf columns made of marble. The building has been a New York City Landmark since 1966, and was added to the National Register of Historic Places on December 28, 1979.
