740 Park Avenue is not stranger to the rich and famous. The infamous, ultra-luxury co-op apartment building on Park Avenue between East 71st and 72nd Streets is one of the most luxurious residential building in New York City and home to some of the world's wealthiest including David Koch and Woody Johnson, amongst others. The apartment that Jacqueline Kennedy Onassis grew up in has finally sold for $25.25 to Jacob M. Safra of the banking family. The duplex unit, 6/7A, was listed for $29.5 million and covers 4 bedrooms and 6.5 bathrooms. The total floorplan features 12 rooms including a library, dining room, grand living room with fireplaces, 3 large ensuite bedrooms, media room and a large master-suite complete with 2 marble bathrooms. The unit was recently renovated by Fox-Hahem Associates. Interestingly enough, 740 Park was developed by Kennedy Onassis' grandfather, James T Lee. The 17 story building was designed by legendary architect Rosario Candela and Loomis Harmon and features 31 units. The sale of 6/7A closed for $25,250,000 and was overseen by Oren and Tal Alexander of The Alexander Team with Douglas Elliman.
