675 W End Ave

675 West End Avenue is a 16-story, 1925 pre-war cooperative located on Manhattan’s Upper West Side within the Riverside-West End Historic District. The masonry façade and articulated marble entry give the building a traditional, early 20th-century presence on a residential tree-lined avenue. With only 11 total units listed in the source set for this building profile, the property reads as a low-density, classic co-op composed largely of one-bedroom residences as well as a range of larger classic-six layouts found in the marketing materials. Interiors commonly feature high, beamed or 9–9.5-foot ceilings, original hardwood floors, picture moldings, gracious entry foyers and extensive built-in millwork; many units retain period details while incorporating renovated kitchens and modern appliances. Common building amenities include a staffed lobby/doorman (part- or full-time variations referenced), a live-in superintendent, elevator service, on-site laundry facilities and bicycle storage. Pet policies are permissive: pets, pieds-a-terre and co-purchasing are generally allowed and subletting is permitted subject to board approval and tenure rules. The building offers limited private outdoor space at the unit level rather than generous communal grounds; most apartments are rear- or avenue-facing with open-sky or park views. Located steps from Riverside Park and close to Central Park, transit includes nearby 1/2/3 and A/C/B/D lines plus robust bus and CitiBike access; neighborhood conveniences include grocery options, fitness studios and cultural destinations. The overall impression is a well-managed, service-oriented pre-war co-op that balances historic character with everyday modern conveniences.
