An extraordinarily rare full-floor penthouse on Fifth Avenue, occupying the crown of one of the Upper East Side's most distinguished white-glove buildings and commanding unobstructed panoramic views across Central Park from every room. The residence has been designed by one of Manhattan's most celebrated interior design firms and represents a singular achievement in New York luxury living — a seamless integration of museum-quality finishes, bespoke craftsmanship, and spatial grandeur that is seldom encountered in the city's residential market. Four bedroom suites, each with custom dressing rooms and en-suite bathrooms finished in rare stone, surround a vast central reception area with 12-foot ceilings and a wood-burning fireplace. A private rooftop terrace crowns the residence, offering 360-degree views of the Manhattan skyline and Central Park. A once-in-a-generation opportunity at one of New York's finest addresses.
