Description

Unit 10 at 891 Park Avenue is a true jewel box nestled in the heart of the Upper East Side. This chic full-floor home is comprised of two-bedrooms, two-and-a-half-bathrooms and a solarium planned in a gracious layout.

The sumptuously appointed private elevator landing sets the tone to the spacious foyer, adorned with classic prewar details including moldings and a preserved vintage mail chute, unique to find inside the residence. Located just off the foyer, overlooking Park Avenue through three oversized west-facing windows, is the stately living room and accompanying dining room. The gas fireplace's mantel along the north wall, a stunning piece of hand-carved Sienna marble with gold Ormolu details salvaged from The Plaza Hotel, anchors the room. Built-in storage with glass shelving symmetrically flanking either side of this dramatic showstopper makes for the perfect dry bar or at-home library for the voracious reader.

The windowed dining area, adjacent to the living room, allows for ideal easy flow while entertaining. Natural light pours through the generous windows and shines bright on the white wood floors found throughout the home. The picturesque kitchen located just a stone's throw away from the dining area is both functional and stylish. Residence #10's custom-made French windows were designed for the kitchen to feel as its own distinct, purposeful space while still allowing for an abundance of natural lighting. This decorative element, alongside brass and gold hardware, introduces a pop of color amidst the clean, white lacquered cabinetry. Final elements of this designer kitchen are comprised of a six-burner Wolf range with vented hood and paneled appliances that include a pair of SubZero refrigerated drawers and a Bosch dishwasher. Stainless steel cabinets curated from the New York Times building put an authentically New York finishing touch on this posh Park Avenue kitchen.

A long gallery with plenty of art walls places the bedrooms in a separate wing of the residence and creates excellent separation of space. Both bedrooms are tucked away in the quiet eastern wing of the apartment, allowing for both peace and privacy. The king-sized primary bedroom has dual south and east exposure and can accommodate the most robust of wardrobes thanks to a large walk-in closet. An updated ensuite marble bathroom, complete with heated floors and spa glass shower, finalize this upscale primary retreat. The second bedroom is also generously sized with a full ensuite bathroom and an idyllic solarium that presents the perfect seating nook.

Additional features of this extravagant residence include a powder room and laundry closet with a stacked in-unit Samsung washer/dryer. Crown and baseboard molding, beamed ceilings, recessed lighting, an abundance of storage, and a heat and air conditioning system can be found throughout the entire home. A private storage unit in the basement transfers with the sale.

This is a rare opportunity to own a full-floor residence in a charming boutique co-op with only 15 units. Built in 1931 by Arthur Paul Hess, 891 Park Avenue features a live-in resident manager as well as doorman on duty 24 hours from Friday to Sunday, and from 7:00am-11:00pm on Monday to Thursday. The co-op allows pied-a-terre ownership, co-purchasing, purchasing in a Trust, 50% financing, and pets, all with Board approval. Taxes here are not included in the monthly maintenance and are covered by a semiannual real estate tax assessment of $11,235. A transfer fee of 3% is payable by the purchaser.
