Four years later, the store moved into the eight-story Second Leiter Building at State and Van Buren Street, designed by William Le Baron Jenney, where it stayed until 1930, after a 1914-15 reorganization into Associated Dry Goods Corp., but keeping the Siegel-Cooper name in Chicago.
[4] The steel-framed construction of the "Big Store", as it was called at the time, enabled the building to have large interior spaces with uninterrupted selling floors, and allowed for skylit courts.
The main floor featured a copy of Daniel Chester French's statue The Republic[5] inside a marble-enclosed fountain.
[4] In 1913–14 J.P. Morgan was involved in combining the company with other retailers as the Associated Dry Goods Corp.[1] Siegel-Cooper declared bankruptcy in 1915,[2] and the New York store closed in 1917, becoming a military hospital during World War I[7] and then a warehouse.
After decades of miscellaneous use as a warehouse, the NBC Television scene shop and the location "The Door", a social services center, the New York building become one of the first of the great dry-goods emporia in the Ladies' Mile to be renovated and re-opened for retail use.
Calling itself "The Anchor of the Avenue", the building's retail tenants as of August, 2021 included Bed, Bath & Beyond, T.J. Maxx, and Marshall's.
