610 W End Ave

Built in 1911–1912 by George and Edward Blum, this 13-story prewar cooperative on Manhattan’s Upper West Side reads like a collection of townhouse-scaled residences stacked into a single, grand building. The architecture and interiors lean classical: high ceilings, broad picture windows, decorative fireplaces, millwork, and extensive built-ins appear throughout larger layouts that range from three- to four-bedroom Classic Eight and multi-room duplex homes to expansive penthouses with wraparound terraces. Residences emphasize formal entertaining — long galleries, oversized living and dining rooms, butler’s pantries, and windowed eat-in kitchens — alongside modernized conveniences such as washer/dryer hookups, renovated kitchens with high-end appliances, two-zone HVAC in some units, and substantial closet storage. Common areas are service-oriented and traditionally restrained: full-time doorman, live-in superintendent, private storage bins, bicycle room, and laundry facilities. Outdoor amenities include a landscaped roof terrace and private garden-like roof deck; select units provide private outdoor terraces or balconies with river and city views. The building is pet-friendly with board approval and maintains white-glove cooperative operations including occasional assessments and a modest flip tax. Located one block from Riverside Park, it sits amid the Upper West Side’s cultural institutions, restaurants, shops, and multiple transit options, offering a quintessential combination of historic detail, generous interior volume, and convenient city living.
