891 Park Ave

891 Park Avenue is an intimate 15-story, pre-war cooperative completed in 1931 and designed by Arthur Paul Hess. The building is composed primarily of full-floor and large multi-room residences, many entered from private elevator landings that emphasize separation between public and private wings. Architecturally it reads as an Art Deco boutique on Park Avenue, with a welcoming Deco entry and generous French windows that admit abundant natural light. Interior features commonly found across units include high beamed ceilings (around nine feet), herringbone or oak floors, crown moldings and built-in cabinetry; many apartments retain classic details such as wood-burning fireplaces, foyer galleries, and original moldings alongside updated kitchens and baths. Typical layouts offer two-bedroom configurations with en-suite bathrooms, walk-in closets, windowed galley or eat-in kitchens, and provisions for washer/dryer installation in several units. Common building services and amenities reflect full-service cooperative living: a live-in superintendent, doorman staffing (full weekend coverage, extended weekday hours), private storage bins for each apartment, and roof deck access. The co-op is pet-friendly, permits pieds-à-terre and co-purchases, and allows up to approximately 50% financing. Additional financial considerations include a semi-annual assessment and a buyer-paid flip tax. Situated between East 78th and 79th Streets, the location offers immediate proximity to Central Park, Museum Mile, Madison and Fifth Avenue retail and dining, and strong public transit and cultural access typical of the Upper East Side.
