Description

A truly exceptional offering of a grand full floor home boasting over 90 feet of Park Avenue frontage, with majestic exposures framed by large picture windows in every room. Flooded with sunlight throughout, the 15th Floor at 820 Park Avenue is a property offering a flawless classic layout, glorious proportions and wide open views both east and west rarely found on Park Avenue, all set atop a distinguished full-service cooperative on a prime corner of the Upper East Side.

Occupying the building's penultimate floor, this residence is entered through a private vestibule and a custom wrought-iron front door. Ceilings rise over 10 feet as sunlight guides you from the formal gallery into the home's south-facing entertaining wing with a stately living room at its core. The living room features wall-to-wall oversized picture windows facing east, showcasing gorgeous open views over Park Avenue and the city beyond. The first of three wood burning fireplaces anchors the room which is also enveloped in intricate picture molding and crown molding overhead. A pair of large pocket doors open from the living room into a handsome corner library bathed in sunlight pouring in through 7 picture windows exposed southeast over Park Avenue and East 75th Street. Also off the living room and adjacent to the library is a beautifully wood-paneled sitting room with a wood burning fireplace that commands the southwestern corner of the building's facade, featuring glorious open city views up 75th Street all the way to Central Park and the glorious buildings along Central Park West. Perfectly situated between the sitting room and a large windowed eat-in kitchen is a formal dining room, accessed from the living room through sculpted wooden pocket doors and also offering open western views. The kitchen is dressed in white marble and currently offers a pass-through dining counter open to the dining room, all stainless steel appliances including a 6-burner gas range/oven with a griddle and a vented hood, twin wall-mounted ovens by Thermador, a full-sized stainless steel Bosch dishwasher and a Subzero French-door style refrigerator/freezer with an ice maker. The entertaining areas are all served by a windowed powder room discreetly located off of the gallery.

The bedrooms are situated in their own dedicated wing, as is ideal. The expansive primary bedroom suite has massive proportions throughout and its own wood burning fireplace. There is a custom dressing room that can accommodate even the most extensive of wardrobes with an array of closets, shelving and draws and contains an additional huge walk-in closet over 11 feet deep. The en-suite primary bathroom is also enormous, currently housing a deep soaking spa bathtub and an oversized glass-enclosed stall shower and easily accommodating a double vanity as well. There are two additional corner bedrooms at the north end of the residence off of their own hall for enhanced privacy. One has a windowed en-suite bathroom with a tub, and the other is serviced by a windowed bathroom with a stall shower just off of the hall. Each could easily be configured as bedrooms each with their own en-suite full bathrooms and walk-in closets. Rounding out the bedroom wing is a separate service space containing a full-sized washer/dryer.

820 Park Avenue was built in 1926 and designed by the esteemed Prix de Rome-winning architect Henry Allan Jacobs. Residents enjoy white-glove privacy and a dedicated staff inclusive of a live-in resident manager and full-time doormen. The building's prime location places it moments from the finest boutiques, restaurants, art galleries and cultural institutions in Manhattan. Pets are welcome, and there is a 3% flip tax payable by the purchaser. Financing is considered case by case.
