Description
Spanning the entire 8th floor of one of Park Avenue's premier cooperatives, this magnificent, four-bedroom, five-and-a-half-bathroom corner residence is a fine example of renowned architect J.E.R. Carpenter's elegant design, stately proportions and exquisite detail. The apartment is beautifully configured, with gracious private spaces separated from grand entertaining rooms, and is bathed in abundant light from enormous windows facing east onto Park Avenue and south onto 65th Street. From hand-cast Butler hardware to the finest custom millwork and finishes, every detail honors the timeless sophistication of this pre-war masterpiece. A private elevator landing opens to a beautiful entrance gallery with large coat closet and elegant powder room. An arched doorway leads to the dramatic expanse of side-by-side living and dining rooms exquisitely paneled in rich pine. The two rooms span more than 37 feet along Park Avenue with sunlight streaming from double windows. The living room features a wood-burning fireplace with intricately carved mantle, coffered ceiling, built-in bookcases and a recessed media cabinet concealed behind antique glass paneled doors. The neighboring formal dining room provides a sumptuous setting for large-scale entertaining and can be separated from the living room by two floor-to-ceiling folding pine doors. A private hallway leads to the four bedrooms, each with en suite marble baths, abundant closets and custom built-in storage. The spectacular corner primary bedroom has a wood-burning fireplace and enjoys lovely views east and south, and forms a suite with the adjacent study, handsomely appointed and with a built-in desk overlooking Park Avenue. The windowed, eat-in kitchen features beautiful cypress wood cabinetry and Statuario marble countertops, and is superbly equipped with a 48-inch SubZero refrigerator, 8-burner vented Viking range and oven, Miele dishwasher, Uline wine refrigerator and SubZero ice machine. Four staff rooms adjacent to the kitchen were reconfigured to create a hallway with a second SubZero refrigerator, a large home office, a full bathroom and a spacious laundry room. A rare and extraordinary addition to this offering is a sun-flooded, private art studio/home office on the building's top floor with access to the common roof deck, and a separate cedar-lined room with a skylight and window. Please note the total monthly maintenance represents $13,774.23 for the apartment, $712.46 for the studio and $296.86 for the cedar-lined room. A separate full-size storage bin also transfers with the apartment. Built in 1924, 620 Park Avenue is a premier, full-service pre-war cooperative comprising 13 full-floor apartments. The building offers a landscaped common roof deck with stunning views in all directions and ample room for outdoor entertaining, as well as a state-of-the-art fitness center. There is a 3% flip tax paid by purchaser, and 50% financing and pets are allowed.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
