Rarely does a home combine the scale, privacy, and outdoor living of a brownstone with the convenience of elevator condominium living. Occupying the entire top floor of a boutique condominium building, this elevator accessible three-bedroom-plus-den, three-bathroom penthouse spans 2,165 square feet, and is complemented by an extraordinary private roof terrace crafted for seamless indoor-outdoor living.

Wrapped in twenty oversized windows on four exposures, this residence is flooded with sunlight from sunrise to sunset, with sweeping sky views and exceptional privacy throughout.

A keyed elevator opens directly into the home, revealing the thoughtfully designed living space. White-oak herringbone floors, soaring ceilings, walnut millwork, and an open floor plan create an atmosphere that is elegant, comfortable, and welcoming.

The heart of the home is a dramatic 28 foot-wide great room where expansive living and dining areas are framed by treetop views and open sky. A gas fireplace, built-in shelving, and abundant natural light create a setting equally suited to everyday family life and large-scale entertaining. Throughout the seasons, the views transform from lush summer greenery to golden autumn leaves; to snow-covered branches in winter; and to flowering pear trees in spring.

French doors open to a den lined with walnut shelving and built-in storage. Currently configured as a home office, the space easily functions as a library, nursery, playroom or fourth bedroom.

The award-winning kitchen pairs beauty with functionality, featuring solid wood cabinetry by purekitchen-imperia, Carrara marble backsplash wall, a generous waterfall island, Wolf cooking appliances, Sub-Zero refrigeration, Miele dishwasher, and ample workspace for cooking, gathering, and entertaining.

Privately situated at the opposite end of the residence, the primary suite enjoys triple exposures, abundant closet space, and open views extending across neighboring brownstone gardens. The spa-inspired bath features radiant heated floors, a soaking tub, walk-in shower with teak flooring, detailed vanity cabinetry, and Waterworks fixtures. Two additional bedrooms offer excellent closet space and skyline views - including One World Trade Center - and are served by two beautifully appointed full bathrooms.

Additional features include a dedicated laundry room with ample storage, zoned central HVAC, integrated Sonos audio, on-demand hot water, and top-of-the-line double-paned windows providing maximum insulation and noise reduction.

The crown jewel of the residence is an approximately 800-square-foot private rooftop terrace and garden with sweeping views extending to the Manhattan skyline. The rooftop functions as an outdoor wing of the home. Accessible by both elevator and stairs, this remarkable space has been designed for living, dining, cooking, entertaining, and gardening.

A wisteria-covered pergola anchors the outdoor living area, while mature landscaping, flowering trees, roses, hydrangeas, and seasonal gardens create a level of tranquility rarely found in New York City. The fully equipped outdoor kitchen features ipe-clad cabinetry, a premium DCS grill with rotisserie, power side burner, refrigerator, freezer, hot/cold running water, Dekton countertops, and generous preparation space. Whether hosting sunset dinners against the Manhattan skyline, tending a morning garden, or enjoying a quiet evening beneath the stars, the rooftop serves as a seamless extension of the home below.
