Gracie Towne House, 401 E 89 Th St, 18/19 E Yorkville, New York

Rarely available, this terraced penthouse four-bedroom, three-bathroom duplex ”in the sky” must be seen to be believed.

Situated on the southeast corner of the building, and boasting open city and river views, the home is sun-flooded all day long. The flow and layout are exceptional, providing for gracious everyday living or entertaining on a grand scale.

The main living space is anchored by a wonderful great room that flows seamlessly to a charming south-facing terrace - an idyllic setting for morning coffee, sunset cocktails, or simply taking in the city skyline. The windowed kitchen is perfectly positioned for entertaining, while a spacious bedroom on the main floor easily doubles as a den, home office, or au pair’s living space, complemented by its own full bathroom. A cozy reading nook is tucked behind the staircase, creating the perfect spot to unwind with your favorite book.

The upstairs wing is dedicated to the private living quarters. The corner primary suite enjoys spectacular light and river views, generous California Closets, and a luxurious five-piece en-suite bathroom. Two additional oversized bedrooms share a convenient full bathroom, providing comfortable privacy for family or guests alike. The upper floor also offers easy access for bringing in suitcases when you’re coming home from vacation, through its own door to the building’s hallway.

Refined finishes throughout include richly stained red oak floors, a striking built-in bookcase wall unit, central forced-air heat and air conditioning, an in-unit washer-dryer, and exceptional storage.
