Description

A truly rare offering, available for the first time in nearly half a century. Situated on one of Chelsea’s most picturesque and gracious blocks, this stunning 25-foot-wide Italianate brownstone, built in 1856, is home to Apartment 7—a residence that has remained untouched by modern over-renovation, preserving its authentic character while offering impeccable upkeep. Just two flights up, this spacious junior one-bedroom with western and southern exposures has soaring 10-foot ceilings, original hardwood floors, and a wood-burning fireplace. These create a warm and inviting atmosphere, while an abundance of storage—including a dedicated storage unit—adds everyday convenience. A welcoming, gallery-like entry hall with two closets leads the way into the apartment. The kitchen, as currently configured, is set along the extended hallway, offering flexibility for future reimagining. The bright living room features west-facing windows and a charming fireplace, while the bedroom enjoys quiet southern light, a full windowed bath, walk-in closet and overhead storage. With the guidance of an architect, the layout presents an opportunity to be thoughtfully redesigned to suit your lifestyle. Perfectly positioned in the Historic Chelsea District between 9th and 10th Avenues, the location is truly exceptional—just one block from the High Line and moments from some of the city’s best restaurants, cafés, and galleries. Nearby Chelsea Piers and Hudson River Park offer amazing fitness and recreational opportunities. With easy access to the A/C/E, L, 1/2/3 trains and crosstown buses, the entire city is at your doorstep. This boutique, self-managed 7-unit co-op is thoughtfully maintained and features a video intercom system and a laundry room with complimentary washer and dryer use. As a small, shareholder-driven building where all residents take an active role, certain policies are in place to preserve its close-knit and well-managed environment; subletting, pied-à-terre ownership, co-purchasing, and gifting are not permitted.
