Rarely does a residence of this scale and caliber reach the market. Masterfully reimagined through a total gut-renovation, Apartment 3DE at The Blackstone is one of Riverdale s largest combined co-op homes. Offering five bedrooms, four full bathrooms, two private terraces (one glass-enclosed), an office/library, and a formal dining room, this residence seamlessly blends the expansive scale of a suburban house with the turnkey convenience of full-service luxury living. Upon entering the grand entry foyer, you are greeted by abundant natural light from three exposures, highlighting the beautifully refinished hardwood floors throughout the entire home and the luxurious Phillip Jeffries wallpaper. The living room serves as a sophisticated hub for relaxation, featuring new recessed lighting, automated window treatments, and a custom built-in entertainment center that cleverly conceals the air conditioning unit. The chef s kitchen is a true showpiece, boasting a new waterfall marble peninsula, custom soft-close cabinetry, and top-of-the-line appliances including a GE monogram refrigerator and oven. Designed for hosting, the space includes two sinks and two dishwashers. Every room in the apartment has been updated with custom window treatments for effortless control and a dedicated AC system has been installed throughout, ensuring window units are a thing of the past. Discrete pocket doors have been installed to create a private guest suite or to neatly block off the playroom and storage areas. The bedroom wing is off the living room, and includes a hall bathroom, two large bedrooms, and a primary with ensuite bathroom. The primary bedroom suite is a serene retreat, featuring a walk-in closet and newly replaced double-pane glass windows specifically designed to keep the space pin-drop quiet. The expanded primary bathroom is a spa-like experience, finished with a marble bench and a custom shower nook. Every bathroom in the home has been gutted and renovated with new shower doors, with the exception of the original door in the office bath. The Blackstone is one of Riverdale s exemplary full-service buildings, located west of the Parkway but just steps from the shops and restaurants of Riverdale and Johnson Avenues. This pet-friendly building offers a live-in superintendent, a doorman available from 7:30 am to 1:30 am, and exceptional outdoor amenities including pickleball and basketball courts and numerous sitting areas. The indoor parking spot is available for $200.00 per month. This is a rare chance to own a turnkey home where every single detail from the replaced windows to the custom millwork has been executed to perfection.
