Sunset light pours across the Hudson River and into this remarkable duplex at The Clarendon . Overlooking Riverside Park from one of the Upper West Side's most storied boulevards, 2D offers the rare combination of townhouse scale and white-glove cooperative living. Meticulously renovated, the six-bedroom, five-bathroom home unfolds across two expansive levels that balance classic prewar elegance with contemporary design. The main level is anchored by a great room framed by sweeping west-facing windows that capture open sky, park greenery, and river views. Intricate inlaid wood floors and a marble fireplace lend warmth and architectural character to the space, while the scale of the room invites both elegant entertaining and relaxed everyday living. A chef's kitchen with floor-to-ceiling cabinetry, Caesarstone counters, and a full suite of Sub-Zero, Wolf, and Miele appliances centers around an oversized island designed for gathering. The private bedroom wing includes a corner primary suite with custom closets and a spa-like marble bath, along with a second primary suite featuring its own dressing room and ensuite bath. Two additional bedrooms and a flexible den or media room complete the level. A sculptural staircase leads to the dramatic lower level, where 10-foot ceilings create an airy, loft-like environment rarely found in prewar cooperatives. A gallery hallway opens to a nearly 30-foot great room with decorative marble fireplace-an ideal setting for entertaining or quiet retreat. French doors reveal a fully equipped in-law suite, while an additional bedroom and bath provide further flexibility. Throughout the home, thoughtful details - including Italian Calacatta marble inlays, sculpted marble windowsills, and quartersawn oak floors with walnut trim - speak to the quality of the renovation. Modern comforts include new windows , in-unit washer dryer and multi-zone central air. Built at the turn of the century, The Clarendon is a full-service cooperative with a full-time doorman , resident manager, fitness center, private storage, bicycle room, and laundry facilities. Positioned at the corner of West 86th Street and Riverside Drive, the building enjoys immediate access to Riverside Park, the Hudson River waterfront, and the best dining, shops, and cultural institutions of the Upper West Side. A residence defined by scale, light, and the timeless beauty of Riverside Drive.
