Central Park Apartments, 59th Street ca. 1828 The Central Park Apartments, otherwise known as the Spanish or Navarro Flats for its developer Jose F. De Navarro, was praised as “the most vast, complete, and permanent apartment houses ever as yet erected in any country.” Stretching 425 feet along the southern edge of Central Park on 59th Street, east of Seventh Avenue, the massive 10-story complex “in the “Moorish style” was composed of eight smaller separate buildings, each named after a Spanish city. Navarro financed his project creatively, according to American Architect and Building News, intending “to erect the buildings in his own name, and sell the apartments absolutely to those who wished to occupy them by means of trust-deeds and perpetual leases.” The buildings could be constructed one by one, and the sale of the finished apartments paid for the construction of the next. The first four buildings—the Madrid, Lisbon, Barcelona, and Cordova—were built in 1883, and the Valencia, Granada, Salamanca, and Tolosa were completed in 1885. The complex was designed by French-born architect Philip Hubert and his firm, Hubert Pirsson & Co., who were credited with originating the cooperative apartment system as well as the duplex-apartment layout in New York. The cooperative apartment system, commenced in 1880, allowed residents to partially and collectively invest in ownership of the building. Each building contained twelve apartments, some of which included up to three floors and up to six bedrooms, a parlor, living room, dining room, and library. Apartments sold for $15,000 to $20,000 with annual maintenance fees from $1,000 to $2,000. The complex was arranged around a system of courtyards that gave light, air, and access to the buildings and the interior of the block.

New York Athletic Club, 1929. Founded in 1868, the New York Athletic Club is a private social and athletic club. The 180 Central Park South location, known as The City House, includes two restaurants, a cocktail lounge, library, ballroom, billiard room, meeting rooms, rooftop solarium, eight floors of guest rooms, in addition to its sports facilities. The athletic floors boast swimming pools, basketball and squash courts, fencing and wrestling rooms, and a judo floor. A Long Island location, known as Travers Island, hosts larger outdoor sporting facilities. The elite club has not existed without controversy. Since its conception, the NYAC was a men-only club. It wasn't until 1989, with pressure from both the city and the United States Supreme court, that the club allowed women to join. The New York Times wrote: "a symbol of masculine exclusivity has bowed to the forces of change and feminine scorn and agreed to accept women as members."
