Experience the pinnacle of Manhattan living in this extraordinary Gramercy Park penthouse condominium - a rare 6,329-square-foot duplex that lives like a true home in the sky, complemented by approximately 1,889 square feet of private outdoor space.

A private elevator opens directly into a gracious foyer, where natural light and open city views create an immediate sense of arrival. From here, the residence unfolds in a clear, well-proportioned layout designed for both daily living and entertaining.

The living room stretches across the Park-facing facade, overlooking the treetops of Gramercy Park and drawing in steady northern light. Adjacent is a separate windowed dining room, positioned to feel distinct yet connected to the main entertaining areas. Just beyond, a library offers an additional entertaining space.

Nearby, the eat-in kitchen is outfitted with custom cabinetry and premium appliances, including a Wolf range and oven, Miele dishwasher, and two Sub-Zero refrigerators. Tucked behind the kitchen is a flexible staff suite or home office with its own full bath.

Three additional bedrooms occupy the lower level, each with a marble en-suite bath, offering privacy and comfort for family or guests. A dedicated laundry room with side-by-side washer and vented dryer completes this floor.

Upstairs, a central staircase leads to a sitting room anchored by a gas fireplace and framed by direct access to a sweeping wraparound terrace. A powder room and wet bar with sink, refrigerator, and dishwasher support seamless indoor-outdoor living. The outdoor spaces include a private plunge pool and hot tub with open skyline views.

The primary suite occupies a quiet corner of the upper level with three exposures. It includes a large walk-in closet and a marble bath with heated floors, dual vanities, a freestanding soaking tub, and a separate steam shower.

Throughout the home, quarter-sawn white oak herringbone floors, marble windowsills, Lutron lighting, and multi-zone central heating and air conditioning underscore the quality of the build.

Located at 18 Gramercy Park South, the Georgian Revival building was originally constructed in 1927 and reimagined in 2013 by Robert A. M. Stern in partnership with Zeckendorf Development. With just 16 residences across 18 floors, the boutique property offers a 24-hour doorman, resident manager, concierge and porter staff, landscaped roof terraces, a private club room, spa, fitness center, and the rare privilege of a private key to Gramercy Park.
