Description

Stephen Sills (decorator) and Charlotte Worthy (architect) have created a truly one-of-a-kind masterpiece at 888 Park Avenue. The apartment was completely renovated, and refinished with chic and new high-end finishes, while retaining the hallmarks of grand prewar Park Avenue buildings. Upon entering the apartment from a semi-private vestibule, one enters a beautifully proportioned gallery which leads to all of the main entertaining spaces which have fine Parquet de Versailles wood flooring. The south facing living room is 29’ in length and has a Louis XIV mantle surrounding a wood-burning fire place. The tabor wood paneled Library can be accessed by the gallery or through the living room and also faces south. A hand painted canvas mural adorns the walls of the gracious formal dining. Off the dining room is a custom wine bar with Polished Bardiglio Imperiale countertops and a Pyrite backsplash, a full-size Subzero wine refrigerator and Miele ice maker. The incredibly spacious chef's kitchen uses some of the finest and durable materials such as Super White Quartzite countertops and backsplash, custom Walnut butcher block island, two generous Super White Quartzite sinks and cork floors. The state-of-the-art appliances include a Lacanche stove from France, double Sub-zero refrigerators with four freezer drawers and double Miele dishwashers. In the corner is a large, custom curved banquette with Pindler fabric perfect for informal dining. A large laundry room, additional bedroom and full bath can be accessed off the rear of the kitchen. All of the main bedrooms are accessed off a private hallway where a lovely powder room also sits. The corner primary suite is sun-flooded with eastern and southern light from the dual exposures throughout the day. The elegant primary bath was created by using Cote D'Azur slab stone throughout and a single, honed block of Bianco Dolomiti for the vanity top. The shower has a window within the space, a beautifully finished cove ceiling and THG Paris fixtures. The ample closet spaces which can be found throughout the suite have been carefully thought out. Each of the secondary bedrooms has an abundance of closet space, built-in cabinetry and beautiful hand painted wallpaper. The secondary bathrooms have polished Quarzo Bianco/Cristallo slab throughout with glass tile showers. Thoughtful additions are found in every detail of the finishes. Sound-proofing has been installed between each of the adjoining bedroom walls making each room a quiet and lovely cocoon for sleeping, and the library perfect for movie watching or business conference calls in the midst of activity in other parts of the apartment. Featured on the cover of Elle Decor, September 2020 as well as the designer’s own well reviewed opus - Steven Sills: A Vision for Design, apartment 12B is a stunning showpiece retaining a sense of Old-World elegance, while replete with the best of today's modern design. Incredible thought and consideration were put into every detail of this completely gut renovated apartment. The incredible proportions and sun-flooded exposure create a space perfect for large scale entertaining, yet wonderfully intimate for everyday living. Rarely does such a newly and thoughtfully finished apartment become available in a building of this caliber.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, 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.
