Introducing Penthouse 9 at Gracie Green - A full-floor showstopper with nearly 1,000 square feet of private outdoor space. Perched atop this boutique Upper East Side condominium, Penthouse 9 delivers the rare kind of outdoor living New Yorkers dream about: two sprawling terraces totaling over 900 square feet, including a 720-square-foot private terrace that spans the full width of the building, framed by open southwest skyline views. It's the ultimate backdrop for indoor-outdoor entertaining, lounging, and everyday living - all in complete privacy.

Inside, the keyed elevator opens directly into a sun-drenched, nearly 50-foot-wide great room with 10-foot ceilings, oversized French casement windows, and wide-plank white oak floors. The expansive living and dining area seamlessly connects to the terrace, creating a fluid, loft-like feel with stunning natural light throughout.

The open chef's kitchen is as functional as it is beautiful, featuring Montclair Danby marble countertops, a large island, sleek white lacquer cabinetry, and a premium appliance package including a Sub-Zero refrigerator, vented Wolf gas range, and Miele dishwasher.

The primary suite is its own private retreat, complete with a second terrace (218 square feet), a walk-in closet, and a spa-like marble bathroom with radiant heated floors, floating double vanity, and walk-in glass shower. Three additional bedrooms offer open exposures, generous closets, and access to well-appointed bathrooms. The home also includes a Bosch washer/dryer and integrated smart wiring for shades, audio, and climate control.

Gracie Green, located at 427 East 90th Street, is an intimate new development with just 21 residences. Amenities include an attended lobby, fitness center, children's playroom, bike room, private storage, and a rooftop lounge. Tucked in a quiet, tree-lined pocket near Gracie Mansion and Carl Schurz Park, it offers rare tranquility with unmatched access to the Q train, Whole Foods, top private schools, and the East River promenade.

Estimated monthly taxes are $4,432 with primary-residence eligibility, compared to $5,373 without.
