Koch and Co, 136 West 125th Street

In 1860 H. C. F. Koch & Co. opened its first store in Greenwich Village, New York, selling dry goods and fancy goods, and in 1875 moved onto Sixth Avenue.In 1891 the business moved to Harlem after Henry Koch commissioned William H. Hume to design a grand new store. This was an extensive five storey, fireproof building in brick, stone and steel. In 1893 the store was enlarged and on September 24 an advertisement announced that the additions to and alterations in their magnificent establishment are now completed. A nearly seamless sixth floor provided another acre of floor space and ten new departments. The business continued until 1932 by which time the neighbourhood had greatly changed. Today the Koch building clings on whilst most of the adjacent commercial buildings have been demolished.
