173-175 Riverside Dr

Constructed in 1925–1926 and converted to cooperative ownership in 1968, this is a full-service, 15-story prewar co-op located along Riverside Drive on Manhattan’s Upper West Side. Designed by noted architect J.E.R. Carpenter, the building occupies the block between West 89th and 90th Streets and offers doorman-attended lobbies on both sides plus a live-in resident manager. Residences are classic prewar configurations—spacious multi-room layouts commonly including formal dining rooms, large foyers, decorative fireplaces, high ceilings, hardwood floors, crown and picture moldings, and generous closet space. Typical unit features reported across listings include built-in cabinetry, eat-in kitchens or butler’s pantries, marble and mosaic finishes in renovated baths, washer/dryers (in-unit or permitted), and large multi-pane windows that provide southern and eastern light and views toward Riverside Park or planted inner courtyards. Building amenities emphasize full-service living: 24/7 doormen, a staffed lobby, fitness center, children’s playroom, game/recreation room, bike and storage rooms (wait lists often apply), laundry rooms, and occasional extra facilities such as a pet washing station. Policies and terms noted across listings include pet-friendly rules, 50% financing allowance, a 2% flip tax payable by the buyer, pied-a-terres typically restricted, and primary-residence purchase requirements. The setting is directly across from Riverside Park, with proximate subway and bus lines, neighborhood shops, and restaurants that define an Upper West Side urban lifestyle.
