10 Sullivan Street, 6A is a sophisticated full-floor residence in downtown Manhattan offering 3,122 square feet of interior space, a remarkable 2,531-square-foot landscaped terrace designed and maintained by renowned landscape architects Harrison Green, 11-foot ceilings, and 360-degree city views. Originally conceived as a three-bedroom home, the residence has been completely reimagined by celebrated designer Mark Zeff as a serene, modern retreat with custom millwork, refined proportions, and a seamless connection to the outdoors. A private elevator opens directly into a gracious vestibule illuminated by natural light from the terrace. Floor-to-ceiling Crittall-style iron and glass walls define the expansive layout while preserving an airy, light-filled volume. The long gallery leads to an exceptional entertaining space. The Living Room, wrapped in curved industrial-style windows, captures sweeping 270-degree southern views toward the World Trade Center and across the Manhattan skyline. The space flows into the Dining Area and open Poliform Kitchen, featuring rich walnut cabinetry, marble countertops, a floating island with breakfast bar, and premium Miele, Sub-Zero and Viking appliances. The spectacular terrace is conceived as an extension of the home, with multiple dining and lounging areas surrounded by lush, mature landscaping that creates exceptional privacy. Pergolas, sweeping city views, integrated lighting and speakers, and a fully equipped outdoor kitchen with Viking grill and refrigerator complete the space. The east-facing Primary Suite is flooded with natural light and features custom built-ins, a dressing alcove, and exceptionally large walk-in closet. The luxurious Primary Bath includes a Poliform Macassar ebony double vanity, steam shower with spa jets, separate water closet, and freestanding soaking tub overlooking a private garden-like section of the terrace, with views toward the Empire State Building and Midtown. Additional spaces include a Library/Sitting Room, originally two en-suite bedrooms, with custom bookshelves, built-in desk and bar with refrigerator and wine cooler. A separate guest area includes a concealed full-size Murphy bed and can function as a Guest Room, Home Office or Playroom.
