Description

A Park Avenue jewel box of uncommon scale. Spanning 1,860 square feet, this exceptional residence has been entirely reimagined with an exacting eye for proportion, materiality and detail. Every element-from the architectural layout to the bespoke millwork and meticulously selected finishes-has been thoughtfully considered and impeccably executed. The result is a home that is both visually striking and effortlessly livable. Southern and northern exposures provide natural light throughout the day, with picturesque views over the historic townhouses of Lenox Hill. Marble surfaces, custom millwork and wide-plank European white oak flooring run throughout the residence, creating a refined and cohesive interior. The home unfolds through a gracious entertaining sequence encompassing a custom wine bar, generously proportioned living and dining areas, a library and a den-offering a sense of depth and versatility rarely found at this scale. The beautifully appointed kitchen features a Wolf range and speed oven, Sub-Zero refrigeration and a Miele dishwasher. The serene primary suite includes two walk-in closets and a bespoke marble bathroom finished with Thassos mosaic, Calacatta Vagli stone, Fantini fixtures and Murano glass handles. Two additional fully renovated bathrooms are executed to the same exacting standard. A thoughtfully designed laundry, storage and mudroom is discreetly positioned off the foyer. The residence also features an integrated Sonos system with in-ceiling speakers and connected televisions throughout. Custom furnishings designed specifically for the home are available by separate arrangement. 650 Park Avenue offers white-glove living in every sense, with a 24-hour concierge, fitness center, on-site parking garage, rooftop terrace with city views and recently renovated common areas. Pied-à-terres and pets are welcome. Central Park, the Park Avenue Armory, Hôtel Plaza Athénée, The Lowell, distinguished private clubs and some of Manhattan's finest restaurants are all within a few blocks. This is the Upper East Side at its most elegant-a fully realized, completely turnkey residence with nothing left to do but enjoy it. All utilities, including electricity, are included in the monthly maintenance. A 2% flip tax is payable by the purchaser. There is an ongoing assessment of $619 per month. Private showings are available Monday through Friday by appointment.

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
