10 Gracie Square, Residence 11/12F Set within one of Manhattan's most distinguished riverfront cooperatives, Residence 11/12F at 10 Gracie Square is a rare legacy property that captures the romance, grandeur, and enduring sophistication of classic New York living. This palatial 10-room duplex revisits the glamour of the 1930s with remarkable authenticity, offering extraordinary scale, architectural pedigree, and sweeping East River views in one of the Upper East Side's most discreet and coveted enclaves. Bathed in natural light and defined by soaring ceilings, grand proportions, and timeless pre-war detail, the residence unfolds with the elegance of a private townhouse suspended above the river. The gracious entrance gallery introduces a sequence of magnificent entertaining rooms designed for both intimate living and large-scale gatherings. A dramatic living room, wrapped in expansive windows overlooking the East River, evokes a sense of serenity and openness rarely found in Manhattan. Original fireplace features, beautifully preserved architectural character, and refined contemporary enhancements create a seamless dialogue between old-world grandeur and modern comfort. The formal dining room, equally impressive in scale and light, flows effortlessly from the living room and is positioned to maximize the residence's mesmerizing water views. Beyond, an expansive butler's pantry and extraordinary eat-in kitchen designed by Frank Pizzurro Architecture & Interiors elevate the home's culinary experience with waterfall-edge quartz countertops, Dolomiti marble slab floors and backsplash, and custom high-gloss exotic wood cabinetry. Sophisticated yet highly functional, the kitchen was conceived to serve both daily living and elegant entertaining with equal ease. A charming breakfast room and private guest or staff suite complete the lower level, where thoughtful flow and extraordinary proportions define every space. Upstairs, six beautifully scaled rooms offer privacy, comfort, and flexibility for modern family living. The primary suite is particularly exceptional - luxurious in scale and wrapped in unobstructed East River views - with soft faux suede wallcoverings, upgraded flooring, oversized panoramic windows, and an enlarged marble-clad bath finished in luminous Thassos marble and striking Italian brass fixtures. Throughout the upper level, the home's rare sense of light, openness, and tranquility continues uninterrupted. Thoughtfully reimagined with a bespoke high-end renovation, the residence honors its original pre-war integrity while introducing elevated contemporary finishes and modernized infrastructure, including a newly installed sustainable central air system. The result is a home of remarkable warmth and sophistication that feels both timeless and entirely relevant for today's luxury buyer. Designed in 1930 by legendary architects Rosario Candela and William Lawrence Bottomley, 10 Gracie Square remains one of Manhattan's most prestigious and architecturally significant white-glove cooperatives. Conceived as a quiet riverfront sanctuary, the building is distinguished by its rare gated porte-cochère , attended entrances on both East 83rd and East 84th Streets, marble walkway, and extraordinary level of privacy and service. With only 42 residences and direct access to Carl Schurz Park and the East River Promenade, the cooperative offers a lifestyle defined by discretion, refinement, and enduring New York prestige. Residence 11/12F represents a truly rare offering - a legacy home for the discerning buyer seeking the scale and presence of a grand townhouse, the effortless service of a premier white-glove cooperative, and the protected beauty of direct East River views. In a market where authenticity, provenance, and privacy have become increasingly scarce, this exceptional duplex stands apart as one of the Upper East Side's most compelling and timeless residences.
