401 W End Ave

Built in 1900, this nine-story prewar cooperative on West End Avenue presents a compact, boutique residential environment with 61 units. Architecturally traditional in vocabulary, the low-rise massing retains original period details—high ceilings (often near 10 feet), crown and picture-rail mouldings, arched doorways, tall baseboards, and hardwood floors with inlaid patterns—carried through many apartments. Units are primarily two-bedroom layouts alongside a mix of one-bedrooms, studios and larger combinations; many homes feature formal foyers, separate dining rooms, windowed kitchens and baths, built-in cabinetry, and pantry or storage closets. Common areas and building services emphasize full-service urban living: a 24-hour doorman, live-in superintendent, full-time porter, elevator service, central laundry, bicycle room and shared storage. Pet-friendly policies, liberal subletting and permissive co-op rules (pied-a-terres, guarantors, co-purchasing, trusts permitted with board approval) make the building flexible for varied ownership arrangements; financing is commonly allowed up to 75–80% depending on unit. Street-level access is softened by semi-private entries and a small internal courtyard for select apartments. The location at West End Avenue and West 79th Street places the building a block from Riverside Park, near Broadway shopping, cultural institutions and multiple subway lines, supporting an Upper West Side lifestyle where historic fabric, attentive staff, and neighborhood convenience are primary draws.
