Description

Move right into this beautiful one-of-a-kind apartment, a light-filled sanctuary in one of Carnegie Hill’s most sought-after white-glove cooperatives. Grand proportions define this elegantly configured four-bedroom, six-and-a-half-bathroom home spanning 4,600 square feet. Impeccably constructed and masterly reimagined, the nine-room B line has been combined with the six-room A line to create an apartment unlike any other in the building. Enter from your private elevator vestibule into the impressive entertaining space consisting of a 19-foot center gallery, which leads to the gracious designer-decorated living room and adjacent dining room bathed in natural light and featuring high beamed ceilings, gorgeous mahogany herringbone floors, a wall of windows, and lovely architectural details. Designed to maximize space and functionality, the masterful kitchen is a chef’s dream come true, offering an abundance of custom cabinetry, multiple prep spaces, stone countertops, and equipped with a suite of high-end appliances including vented Wolf 6-burner plus griddle range and double ovens, 48” Sub-Zero refrigerator, Miele dishwasher and espresso machine, additional undercounter Sub-Zero refrigerator, and 150-bottle Traulsen wine refrigerator. The center island and banquette seating for 8 make this an ideal space for all your social gatherings and the two separate pantry spaces, one with wet bar, provide copious amount of extra storage. Rounding out the public rooms is a lovely office (which could also function as a fifth bedroom), guest powder room, and an expansive and sun-splashed corner den/media room and library with artfully designed built-ins and an ensuite full bathroom, offering versatile use of space, perfect also as a game room or guest bedroom suite. A grand private hall houses the luxurious primary suite and three additional generously-scaled bedrooms. The expansive primary suite with an exquisitely detailed marble fireplace mantel as its centerpiece and sunny southern views onto tree-lined 87th Street is an urban sanctuary, boasting two ensuite bathrooms, one with a tub and the other with a glass stall shower. In addition to a wall of built-in storage, there are two lavish dressing rooms finished with custom built-ins and a vanity. The second oversized bedroom has custom built-in bookcases and desk and a beautiful spa-like ensuite bathroom with marble floors and large glass stall shower. The third and fourth bedrooms share a large bathroom with double vanities, huge glass shower, and lovely marble tile floors. The suburban-sized laundry room is fully equipped with Whirlpool washer, vented LG dryer, a sink, and custom cabinetry for utility and linen storage. A multi-zone HVAC system controlled by remote Honeywell wireless thermostats, Sonos sound system in the public spaces, CitiQuiet windows, exceptional custom closets, and enviably low monthly maintenance for an apartment of this size complete this not-to-be-missed special home. Designed by renowned architect Emery Roth, 21 East 87th Street is one of Carnegie Hill’s most desirable white glove buildings, moments from Central Park and nestled among prominent museums, charming boutiques, and Manhattan’s finest private schools. Building amenities include a 24-hour doorman, resident superintendent, fitness center, common laundry, bike room, and private storage. Pets are welcome and 65% financing is permitted.
