Opportunity Knocks with This Exceptional Oversized One-Bedroom Home! A rare opportunity to create a true two-bedroom residence in one of Riverside Drive's most distinguished pre-war cooperatives. This oversized, high-floor home offers timeless architectural elegance, gracious proportions, and a flexible floor plan with exceptional potential with E, N and S exposures. Many owners of the coveted G-line have successfully converted these residences into two-bedroom homes (see alternate floor plans), making this a unique opportunity to customize the space to suit your lifestyle. A welcoming entry foyer opens into a spacious living room with a separate dining area—ideal for both everyday living and entertaining. Beautifully renovated and bathed in natural light from eastern and northern exposures, the home showcases soaring 9'6" ceilings, hardwood floors throughout, generous closet space, and classic pre-war charm. The windowed chef's kitchen has been thoughtfully renovated with striking Blue Pearl marble countertops, light blue glass tile backsplash, and custom white cabinetry extending to the ceiling for exceptional storage, including generous pantry cabinets surrounding the refrigerator. Premium appliances include a Miele dishwasher, GE Profile gas range, and brand new Frigidaire refrigerator. The expansive king-sized bedroom provides a peaceful retreat, while the renovated windowed bathroom features crisp white tile, classic period-inspired patterned floor tile, and timeless white fixtures. A large private storage cage is also included with the apartment. Building was started in 1909 and completed in 1910 by renowned architect George Pelham and originally known as The Cliffden, this elegant 70-residence cooperative is a stunning example of classic pre-war architecture. Situated on a quiet, picturesque block of Riverside Drive at West 99th Street, the building is distinguished by its dramatic curved façade, three-story limestone base, and stately columned entrance. Residents enjoy a full complement of amenities, including a beautifully restored lobby, part-time doorman service (4:00 PM–12:00 AM, seven days a week), three elevators, a live-in superintendent, full-time porter, bike storage, basement laundry, and private storage. Pet lovers will appreciate the building's welcoming policy, allowing cats and one dog up to 85 pounds. Perfectly positioned directly across from Riverside Park and the Hudson River Greenway and just moments from Central Park, the location offers the very best of Upper West Side living. Whole Foods, Trader Joe's, neighborhood cafés, acclaimed restaurants, boutiques, and multiple transportation options are all close by. Combining generous proportions, classic pre-war character, modern updates, and the rare opportunity to create a two-bedroom home, this exceptional residence offers the perfect blend of comfort, flexibility, and location on one of the Upper West Side's most iconic boulevards.
