Description
Perched high above the Upper East Side, this exceptional penthouse duplex at The Kingsley offers a rare combination of sophisticated design, dramatic city views, expansive outdoor space, and thoughtful custom craftsmanship throughout. From the moment you arrive, a gracious entry foyer sets the tone for the residence, featuring custom millwork, designer wall coverings, and elegant detailing that immediately convey a sense of refinement and warmth. The main level is designed for both comfortable daily living and effortless entertaining. A sprawling living and dining area is framed by sweeping eastern and southern exposures, filling the home with natural light throughout the day while showcasing some of the most captivating views in the neighborhood. From this elevated vantage point, the residence enjoys a dramatic panorama of the Manhattan skyline. The views are particularly spectacular at night, when the city lights create a stunning backdrop, and during seasonal celebrations when fireworks can be enjoyed from the comfort of home. A wood-burning fireplace serves as a beautiful focal point, creating an inviting atmosphere year-round. Just beyond, the reconfigured chef’s kitchen has been thoughtfully renovated to maximize functionality and storage, featuring custom cabinetry with integrated pull-out organizers, extensive counter space, a Sub-Zero refrigerator, Thermador range, wine refrigeration, and premium finishes throughout. Every detail has been carefully considered, from the custom lighting and glass accents to the seamless built-ins concealing the upgraded HVAC systems. A striking staircase with glass detailing leads both upward to the private outdoor terrace and downward to the bedroom level. The landscaped terrace provides a serene retreat above the city, complete with irrigation and ample space for outdoor dining, entertaining, or simply enjoying the panoramic skyline views and seasonal fireworks displays. The lower level offers a private bedroom wing anchored by a tranquil primary suite with spectacular open views, generous closet space, and a luxurious en-suite bath featuring dual vanities, a soaking tub, and designer finishes. The spacious second bedroom enjoys corner exposures, custom built-ins, an en-suite bathroom, and abundant natural light. An additional flexible area on this level provides excellent potential for a home office, library, media room, or guest space. Throughout the residence, custom closets and intelligently designed storage solutions maximize functionality without compromising aesthetics. This fully renovated home showcases exceptional attention to detail, including custom moldings, designer wallpaper, premium flooring, integrated speakers, bespoke built-ins, upgraded mechanical systems, and high-end finishes throughout. The result is a residence that feels both elegant and highly livable, with a level of customization rarely found in condominium living. The Kingsley is a highly regarded full-service condominium offering residents a 24-hour doorman, concierge, live-in resident manager, fitness center with panoramic city views, residents’ lounge, laundry facilities on every floor, and on-site garage parking. The building provides the convenience and service expected of one of the Upper East Side’s premier residential addresses. Ideally situated on East 70th Street, the residence is moments from the neighborhood’s renowned restaurants, boutiques, and everyday conveniences. Central Park, Carl Schurz Park, and the East River Esplanade are all nearby, while the Q train and multiple transportation options provide effortless access to the rest of Manhattan.
