Residence 3B offers a rare opportunity to craft a bespoke home in the heart of Carnegie Hill, one of Manhattan’s most storied and sought-after enclaves. Perched above Madison Avenue and moments from Central Park, this sun-filled corner residence combines classic prewar elegance with exceptional renovation potential. Currently configured as a two-bed, two-bath home, the residence features gracious proportions, oversized windows, and desirable south and west exposures that flood the interiors with natural light throughout the day. The expansive entertaining spaces lend themselves beautifully to a refined living and dining experience. The entryway sets the tone for the residence and offers the perfect canvas for custom millwork, curated art display, or a sophisticated bar for entertaining. The kitchen, positioned just off the dining area, can be fully reimagined into a chef’s kitchen tailored to contemporary living. The private bedroom wing is thoughtfully separated from the public spaces. The generously proportioned secondary bedroom offers flexibility for guests, a home office, or library. The corner primary suite enjoys dual exposures and ample space for a re-envisioned en-suite bath and custom walk-in closet. A second full bathroom conveniently serves the additional bedroom and guests. Residence 3B presents a true blank canvas—an exceptional opportunity to design a custom residence of enduring elegance in a premier Upper East Side cooperative. 49 East 86th Street is a distinguished full-service Art Deco cooperative built in 1931 by the acclaimed firm Pennington & Lewis. The building offers a full-time doorman, live-in resident manager, bike room, laundry facilities, private storage, and is pet-friendly. Perfectly situated on Carnegie Hill’s Gold Coast, residents enjoy immediate access to Central Park, Madison Avenue boutiques, world-class dining, cultural institutions, and convenient transportation.
