This slim 43-story tower is Park Avenue's tallest residential building. Completed in 2000, the pet-friendly condominium tower contains only 38 apartments. Those above the 15th floor offer stunning panoramic city views. The handsome, spindly tower???which seems taller than its 43 stories because it has 10-foot-high ceilings???joins the nearby Four Seasons Hotel in giving the district north of 57th Street a new skyline. Apartments at this full-service building have entrance foyers, and twelve of the 38 are duplexes. The building offers a fitness center, wine cellars, a private dining room available for catered affairs, and a residents-only library in addition to a doorman, concierge, storage facilities and central A/C. Its prime Midtown location puts the city's main business district, shopping, restaurants, transportation and Central Park only a short walk away.
