Listing Notes

First time offered, this exceptional Park Avenue maisonette is a rare and distinguished three-bedroom, two-and-a-half-bath residence, discreetly positioned with a private entrance on 73rd Street-offering the privacy of townhouse living with the prestige of a premier cooperative. A grand entry foyer serves as a central gallery, elegantly dividing the entertaining rooms and establishing a seamless, gracious flow. The scale is immediately apparent: oversized room proportions and soaring ceilings are complemented by exceptional light from multiple exposures on all sides-an uncommon offering that floods the interiors with natural light throughout the day and enhances the sense of openness and volume. Impeccably reimagined in 2011 by the acclaimed architects Lubrano Ciavarra, the renovation was guided by a commitment to restore the integrity of this Rosario Candela-designed landmark, originally built in 1930. The result is a masterful balance of architectural authenticity and modern refinement. The formal rooms retain their original grandeur, complete with classic moldings, while rich Honduran mahogany flooring runs continuously throughout. A sophisticated material palette underscores the home's quiet luxury. The Art Deco entry vestibule is clad in full slabs of polished Absolute Black granite, Corinthian Beige, and Crema Bianco. The kitchen is finished in soft Rosa Aurora marble, and the primary bath is appointed with striking slabs of exotic green-brown Madreperola-each selection curated for both beauty and permanence. Elegant in its restraint and exceptional in its execution, this is a residence of true pedigree-offering scale, provenance, and discretion in one of Park Avenue's most coveted addresses. 770 Park Avenue is an intimate and highly coveted white-glove cooperative comprised of just 42 residences. Ideally positioned moments from Central Park and in close proximity to The Frick Collection and the Whitney Museum, the building offers full-time doormen, a live-in resident manager, a fitness center, and laundry facilities. Ownership is subject to a 3% flip tax payable by the purchaser; financing is not permitted. Pets and pied-à-terres are considered on a case-by-case basis, and summer work rules apply.
