The area is dominated by factory and warehouse buildings constructed in the mid-to-late 19th century, convenient to the railroad yards, of which the Oak Point Yard is the main survivor. Notable early businesses were the R. Hoe Co.; Cutler & Hammer Tool Works; Mothers Friend Shirt Waist factory (1888) at Willow Avenue between East 135th and 136th Streets; and the Estey Piano Company Factory (now designated a city landmark by the New York City Landmarks Preservation Commission). While many of the early industrial buildings remain, they are little used for manufacturing anymore.
