A.I. Namm & Son Department Store and Offerman Building Designated. On March 15, 2005, Landmarks designated the A.I. Namm & Son Department Store and the Offerman Building, both located on Fulton Street in downtown Brooklyn.
The A.I. Namm & Son Department Store, 450-458 Fulton Street, first opened in 1891 at 452 Fulton Street and gradually expanded in 1924-25 and 1928-29. Robert D. Kohn and Charles Butler created a modern design with a structural steel frame reinforced by concrete floors, Indiana limestone cladding and a horizontal tripartite division. In approving, Landmarks noted that the building is a significant architectural remnant of Brooklyn’s late nineteenth and early twentieth century commercial nucleus.
