Commissioners voted unanimously to approve district two years after initial hearing, though split on the inclusion of modern apartment complex. On June 25, 2013, the Landmarks Preservation Commission voted to approve an extension to the West End-Collegiate Historic District, encompassing 200 buildings. The extension more than doubles the size of the previously designated district, and lies to the north and to the south of the original district, between 70th and 79th Streets, and Riverside Drive and Broadway. The district is primarily residential, characterized by rowhouses and apartment buildings built in the period between the 1880s and the 1930s.
The first wave of development in the area saw the construction of single-family rowhouses, constructed in brownstone, limestone, and brick in a variety of architectural styles, including Beaux-Arts, Queen Anne, Renaissance Revival, and Romanesque Revival. In the 1890s, as apartment living lost its stigma among the upper class, the neighborhood saw the construction of several “French flats” or small, multi-family dwellings. Through the turn of the century to the turn of the 1930s, elevator apartment buildings dominated new construction.
