Residence 12F is a beautifully proportioned one-bedroom, one-bathroom home offering a rare blend of privacy, scale, and enduring pre-war elegance. A gracious gallery opens to an expansive living room with ample space for dining and entertaining, while a beautifully arched hallway leads to the oversized eat-in kitchen, featuring extensive storage, stainless-steel appliances, quartz countertops, a windowed breakfast nook, and additional space for dining or a pantry. In-unit washer/dryer installation is permitted with board approval. The serene king-sized bedroom easily accommodates a full suite of furnishings and enjoys lovely natural light throughout the day. A bright windowed bathroom retains its original charm with a cast-iron tub and porcelain sink. Storage is exceptional, with four large closets—including a walk-in currently used as a voiceover studio—along with a wall of original built-ins with overhead storage. Hardwood floors, 9.5-foot ceilings, picture-frame moldings, and beamed ceilings further enhance the home’s timeless character. The Riviera is a landmarked Beaux Arts cooperative built in 1910, distinguished by its striking marble lobby, hand-painted coffered ceilings, three entrances, full-time doorman, live-in superintendent, central laundry, handymen, and porters. Located in the Audubon Park Historic District directly across from Riverside Park, the building is one block from the 1 train, one stop from the A/C trains at 168th Street and Columbia University Medical Center, and moments from the Henry Hudson Parkway for convenient access in and out of the city. Pets, co-purchasing, guarantors, parental purchasing, pied-à-terre ownership, and in-unit washer/dryer installation are permitted with board approval. A monthly assessment of $374 is in place through December 2026, which the seller will pay in full at closing.
