Description

Welcome to 21 East 87th Street, Apartment 6D, a stunningly renovated classic seven-room home in a premier Carnegie Hill cooperative. Spanning approximately 2,400 square feet, this elegant three-bedroom, three-bath residence offers a rare combination of scale, comfort, and prewar detail. A gracious gallery opens into a well-proportioned floor plan with exposures to the east, west, and north, providing pleasant natural light throughout the day. The expansive living room features a decorative fireplace and flows into the dining room or den, ideal for entertaining. At the heart of the home is the oversized chef’s kitchen, thoughtfully designed with marble countertops, custom cabinetry, high-end appliances, and a relaxed eat-in area. Just beyond the kitchen is a home office with built-in millwork, a washer and dryer, and a full en-suite bath. It can also serve as a cozy fourth bedroom. The private bedroom wing includes three generously sized bedrooms, including a serene and exquisite primary suite with a windowed marble en-suite bath featuring a shower, and a walk-in closet. Located just one block from Central Park, 21 East 87th Street is an Emery Roth–designed building offering a full-time doorman, live-in superintendent, fitness room, bike room, private storage room, and laundry room. A monthly capital assessment of $785.83 is in place through December 2025. The building is pet-friendly, permits up to 65% financing, and has a 2% flip tax.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
