Residence 9J A Unique Duplex with Exceptional Design and Detail Located in a classic pre-war condominium on Park Avenue South, Residence 9J is a fully renovated duplex that combines thoughtful design, high-end finishes, and modern technology. Every part of the home has been carefully planned to create a comfortable and elevated living experience. A private elevator opens directly into the apartment, where a dramatic double-height living space with approximately 23-foot ceilings makes an immediate impression. Large, deep-set windows on multiple exposures bring in great natural light throughout the day, giving the home an open and airy feel. The kitchen is a true centerpiece. Custom-built by Officine Gullo in Florence, it features an 8-burner range and top-quality appliances. Both beautiful and functional, its well-suited for everyday cooking as well as entertaining. The home is fully equipped with a Crestron system integrated with Lutron, allowing you to control lighting, climate, sound, security, and window treatments from your phone or in-wall panels. Custom details can be found throughout, including a silk-wrapped staircase, a high-gloss black and silver leaf banister, hand-finished outlets, and clean, trimless lighting. Upstairs, the private level includes two-bedroom suites. The primary suite offers custom closets with a built-in safe, a McIntosh audio/video system, and a spacious, spa-like bathroom. All bathrooms are finished with high-end materials such as Bisazza tiles, Boffi fixtures, Zuma and Hastings soaking tubs, and Dornbracht and Fantini fittings. This is a carefully designed, fully customized home with a level of detail rarely seen. Residence 9J offers a one-of-a-kind living experience in a full-service condominium just moments from Union Square.
