Abundant light, breathtaking views, and elegant design coalesce at this sprawling Robert A.M. Stern sky mansion spanning over 4,600 square feet with four bedrooms, four and half bathrooms, smart home technology, and soaring 11-foot ceilings.

Situated directly on Park Avenue just two blocks from Central Park, this exquisite full-floor residence represents one of the finest examples of contemporary sophistication and timeless Lenox Hill luxury. Peerless in volume and scale, the home is wrapped in floor-to-ceiling windows that offer dramatic cityscapes and serene Central Park vistas all year round.

A private elevator landing leads through brass-trimmed French doors into a marble-clad gallery adjoined by formal living and dining rooms and a spacious library. The living room enjoys two exposures and is ideal for gatherings, while the dining room flows into an open-concept kitchen and family room. The family room is equally suited as a breakfast nook or secluded home office.

The sublime Christopher Peacock kitchen overlooks the park and is a dream for any home cook or entertainer. It is equipped with a large island, an eat-in peninsula, sleek marble countertops, and a suite of high-end stainless steel appliances from Wolf, Miele, and Sub-Zero.

The primary suite occupies its own wing and receives vibrant morning light. It has two bay windows, two walk-in closets, and a spa-like en-suite bathroom with marble walls and floors, a double vanity, a walk-in steam shower, and a separate soaking tub.

Each of the secondary bedrooms has been thoughtfully customized, offering private closet space and windowed en-suite bathrooms. The spacious library can easily be converted into a fifth bedroom, making this home perfect for large families or those in need of additional space.
