Property Description for 21 East 87th Street, 6-B

An exceptional offering of a majestic, sun-drenched, all exterior-facing corner classic 9-into-8-room home in one of Carnegie Hill's most sought-after Emery Roth pre-war full-service luxury cooperatives. The B-line residences at 21 East 87th Street seldom come to market and are prized for their unparalleled light, grand proportions and a perfectly balanced layout that lives as beautifully as it entertains, as demonstrated in Residence 6B. This is a once in a generation opportunity to create a uniquely glorious home on a coveted park block surrounded by the best that life on the Upper East Side has to offer.

Enter off of a semi-private landing and be welcomed into a gracious entry gallery from which both the entertaining spaces and private quarters seamlessly flow. Before you is a grand living room in which warm eastern sun pours through oversized double-hung windows overlooking Madison Avenue. At approximately 25 feet deep, the living room feels both expansive and inviting, anchored by a handsome decorative marble fireplace and framed by high beamed ceilings carried throughout the home. Immediately adjacent to the living room is the formal dining room, also grand in scale and adorned by the sunlight and views of Madison Avenue. Accessed through an elegant pair of French doors, it joins the living room in creating a flawless space for entertaining at scale.

Rare in pre-war design, the kitchen enjoys sun-filled exterior avenue exposures as well. Having absorbed a second service room, the double-windowed eat-in kitchen is massive, offering a space that's primed for a top-tier re-imagining of an enviable dining kitchen with ample room for every top-of-the-line appliance you might want, abundant counter space, vast storage, and a casual dining area as well. It has an adjacent pantry with a prep sink on one side and a sizable east-facing staff room/home office with an en-suite full bathroom on the other.

Carnegie Hill | Manhattan

Quick Profile

Carnegie Hill is a small neighborhood at the northern tip of the Upper East Side that borders Central Park. It is steeped in history, great wealth, architecture and culture. It is known for its world-class museums and its rows of historic mansions. Nothing much changes here as the entire area is landmarked, preventing the proliferation of high-rise developments. Thus the buildings stay a human scale, the sky is aplenty and the neighborhood kind of feels like a small town to its long time residents.

The name Carnegie Hill is derived from the industrial magnate Andrew Carnegie, when Carnegie decided to build himself a mansion at 91st Street and Fifth Avenue….

Carnegie Hill is a family neighborhood with old fashioned upper crust money. The mid-rise co-ops that line the avenues are among the most prestigious addresses in the city. The avenues are lined with small restaurants, boutique shops

The residential towers that have proliferated on the eastside of Third Avenue in the East 90s simply do not exist between Lexington and Fifth.
