Just moments from Central Park, this beautifully reimagined four bedroom plus home office, three bathroom duplex presents a rare combination of scale, architectural character, and modern refinement in the heart of the Upper West Side. The residence occupies the fourth and fifth floors of a distinguished prewar cooperative built in 1909. The building reflects the architectural elegance of early twentieth century Manhattan, while the apartment itself has been thoughtfully renovated to meet contemporary standards of comfort and design. Upon entry, the sense of proportion and craftsmanship is immediately apparent. Period details have been carefully preserved and enhanced through a comprehensive renovation, creating a seamless dialogue between historic charm and modern luxury. The upper level is dedicated to entertaining and daily living. A generously scaled double living room is filled with natural light from oversized south facing windows, offering both openness and warmth. Adjacent to the living room, the oak paneled dining room, highlighted by a graceful bay window, provides a sophisticated setting for formal dinners as well as intimate gatherings. The windowed eat in kitchen has been meticulously designed with custom floor to ceiling cabinetry, a full suite of Bosch appliances, and elegant quartz countertops. A central island and built in seating area offer generous workspace and casual dining options, while an expansive pantry delivers exceptional storage rarely found in prewar residences. Every element reflects careful planning and elevated design. Also on this level, a refined library or home office features custom built in shelving and additional storage, well suited for work, study, or quiet retreat. High ceilings, wide plank oak flooring, and thoughtfully placed recessed lighting contribute to the residence's polished atmosphere. The lower level is devoted to the private bedroom wing. The south facing primary suite includes a separate sitting area that can be discreetly divided through French doors, allowing flexibility of use. Oversized windows and architectural detailing provide beautiful natural light and a sense of tranquility. The en suite bath is finished with selected marble, mosaic tilework, and premium fixtures, creating a serene and sophisticated environment. Additional bedrooms are well proportioned and served by two full windowed bathrooms, each appointed with quality materials, refined finishes, and spacious showers designed with comfort and style in mind. The building is well maintained, pet friendly, and offers a live in superintendent. Financing is permitted up to eighty percent. A private storage unit is included. Located just half a block from Central Park and in close proximity to neighborhood markets, cultural institutions, and multiple subway lines, this residence represents a compelling opportunity to own a thoughtfully curated duplex in one of Manhattan's most established residential enclaves.
