Description

Move right in to this beautifully renovated and immaculately maintained 10 into 9 room duplex in one of J.E.R. Carpenter’s most desirable buildings. The cozy entrance vestibule leads to a truly impressive gallery with a sweeping circular staircase, setting the tone for grand entertaining and gracious living, with ceiling heights of 10 feet throughout the first floor. Arched openings lead to a cozy paneled and lacquered library with wet bar and a light filled living room. The south facing dining room is entered through well scaled double doors and leads to a carefully outfitted pantry, with icemaker and wine refrigerator, and a light filled kitchen with dining area. Upstairs, a spacious landing leads to the sunny south facing primary bedroom, complete with marble bath and two walk-in closets. Two additional spacious bedrooms and windowed bathrooms face north, across the hall. There is a second-floor laundry room as well as a cozy two room staff suite, complete with full bath. Offered in excellent condition, this home was finished to the highest standards of a classic Park Avenue residence. Ideally situated at East 75th Street, 812 Park Avenue features a classically grand lobby and a beautifully landscaped central courtyard garden. The building staff includes full-time doormen and porters, elevator attendants, and a resident manager. There is a recently renovated first floor fitness center that overlooks the beautifully planted garden. Co-Exclusive with John Yunis of Corcoran.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
