Description
NEW TO MARKET! An exceptionally rare 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.
The private quarters are all ideally arranged on the south side of the apartment, crowned by a king-sized corner primary bedroom suite bathed in southeastern sun, with a windowed 4-fixtured primary bathroom and a large dressing room. The bedroom adjacent the primary suite faces south over 87th Street and is currently in use as a library serviced by an en-suite windowed full bathroom with a stall shower. There are two more sizable bedrooms with share a windowed full bathroom with a stall shower. Both bedrooms face south over East 87th Street, and each of them has its own large walk-in closet.
Built in 1927 and conceived by famed architect Emery Roth, 21 East 87th Street is one of Carnegie Hill's most beloved buildings. A full-time doorman and live-in resident manager provide polished and attentive service, and the building features a gym, central laundry, bicycle storage and private storage for each residence. Residents enjoy immediate access to Central Park, Museum Mile and the finest cultural and educational institutions, restaurants, entertainment and shopping that New York City has to offer. Pets are welcome. There is a flip tax of 2% of the purchase price, and financing is allowed up to 65%.
