At nearly 1,850 square feet, Residence 1C is a rarely available expanded version of the building’s C line, offering unusually generous proportions and preserved pre-war detail. With three true bedrooms plus an additional library, the home provides an uncommon balance of entertaining space and private retreat. Elevated nearly a full floor above grade, the apartment evokes the scale of a high-ceilinged parlor level in a Gilded Age townhouse, set above the street with both light and outlook. A long, gallery-like foyer introduces the home and immediately establishes a sense of proportion. The living room sits at the center of the plan, measuring over 13 by 16 feet and comfortably accommodating multiple seating areas. Just beyond, a separate library extends the public rooms and offers flexibility as a media room, study, or additional sleeping space. Richly ornamented 10-foot ceilings, original hardwood parquet floors, and a decorative fireplace preserve the apartment’s classic prewar character. Together, these front-facing rooms stretch across more than 40 feet of linear frontage, overlooking the breadth of West 86th Street as it terminates at Riverside Drive and the park beyond. The windowed eat-in kitchen is privately positioned along the central hall and offers abundant pantry and storage space. Renovated with inset shaker cabinetry detailed with brass latches, marble and stainless-steel countertops with integrated sink, and Viking appliances, the kitchen is both beautiful and highly functional. The bedrooms are arranged along two distinct wings. The well-proportioned primary bedroom occupies a quiet corner with oversized windows and excellent closet storage. Its renovated en-suite bath features a spa-like shower and custom cabinetry. Four hall closets provide substantial additional storage and conceal the washer-dryer. Two additional bedrooms sit along the end of the corridor, creating an ideal split-bedroom layout. Both rooms feature carpeted floors, custom built-in cabinetry, and generous closets. A second full bath with a tub is conveniently positioned between them. 340 West 86th Street is a well-regarded prewar condominium known for its solid construction, gracious layouts, and attentive staff. Residents enjoy a full-time doorman, live-in superintendent, landscaped roof deck, playroom, laundry, and bike storage. Riverside Park is moments away, with Central Park, the Broadway corridor, and multiple transportation options all nearby. For buyers seeking the scale and architectural character of a classic parlor-floor residence within a full-service Upper West Side condominium, Residence 1C offers a compelling alternative to townhouse living.
