Many of the avenue's older apartment buildings, and hotels, were designed with deep "wells," or "courts," to provide more "light and air," but such designs often were a bit dreary. This building, however, is quite attractive because of its good detailing and the deeply recessed entrance that adds considerable grandeur.

Interestingly, it is directly across the avenue from another "light well" building at 829 Park. Although this building is closer to the fashionable restaurants, boutiques and galleries of Madison Avenue and Central Park than 829, many of its apartments have rather jarring views of the "pink" pavilion of Lenox Hill Hospital across the avenue at 77th Street. On the other hand, 830 is on the same block as the entrance to the Carlyle Hotel, one of the city's most elegant.

The 12-story apartment building was erected in 1912 and converted to a cooperative in 1953. It has 78 apartments and was designed by in neo-Georgian style by George and Edward Blum, who also designed 555, 791, 840, 940 and 1075 Park Avenue.

A local subway station is at 77th Street and Lexington Avenue and cross-town buses run on 79th Street.
