A luxury penthouse duplex, nestled between nearly 2,000 square feet of front and back outdoor space in the middle of Manhattan, is considered a rare gem. This Flatiron District residence was uniquely designed for the discriminating buyer who seeks privacy and the perfect oasis to escape the rush of the City, while still offering a loft-like feel as soon as you step out of the elevator. Surrounded by windows, most looking out onto the private terraces, this home offers exposure from three directions resulting in an abundance of sunlight throughout the day. Currently configured as a 2-bedroom with library and 3 baths, this home can easily be converted back into a proper 3 bedroom as the floorplan suggests. The home has been carefully appointed with only the best materials and appliances one would expect in a luxury apartment, including a wood-burning fireplace cased in imported marble, sophisticated custom woodwork, built-in sound system, radiant heat flooring in master bath, Sub-Zero and Miele appliances, and central heat and air. The private terraces are perfect for entertaining or a quiet and tranquil evening, complete with hot tub and endless possibilities for a garden like paradise. The Altair 20 provides an attended lobby, a fitness center and additional storage.
