645 W End Ave

A distinguished prewar cooperative on Manhattan’s Upper West Side, built in the early 20th century and rising 12 stories, the building embodies turn-of-the-century Edwardian/Beaux-Arts character. Designed with generous proportions, the stock of homes are classic multi-room layouts often configured as three-bedroom Classic Six residences with formal dining rooms, entrance foyers, and tall ceilings. Interiors commonly retain restored original details — oak and parquet flooring, picture-frame moldings, wood-paneled dining rooms, beamed ceilings, stained-glass windows and decorative fireplaces — while many units feature modernized chef’s eat-in kitchens and fully renovated baths. The building operates full-service with a 24-hour doorman, live-in superintendent, attended lobby and on-site staff support; common areas have been refreshed periodically. Shared amenities concentrate on an extensively planted roof deck with Hudson River vistas and a rooftop fitness room; practical conveniences include bicycle storage, individual storage bins, laundry facilities and additional storage rooms. Policies are owner-friendly: pets are allowed, in-unit washers/dryers are permitted with approval in some apartments, and the co-op considers guarantors, pied-a-terres and gifting on a case-by-case basis. Located steps from Riverside Park and Broadway, the address provides immediate access to waterfront green space, neighborhood dining, cultural institutions and multiple transit options, positioning the building for both grand-scale entertaining and a relaxed Upper West Side lifestyle.
