Description

Experience classic Park Avenue living in this elegant corner two-bedroom, two-bath residence, offering approximately 1,683+/- square feet within one of Park Avenue’s most distinguished pre-war condominiums. Flooded with natural light from oversized windows on three exposures, the home enjoys sweeping views along Park Avenue and to Central Park. It is defined by soaring 10.5-foot ceilings that enhance the sense of space throughout. The living room is particularly well-proportioned—nearly square in layout—making it exceptionally easy to furnish and flexible for a variety of seating and entertaining arrangements. A decorative fireplace, set along a short dividing wall between the living and dining rooms, creates a natural separation while maintaining an easy, comfortable flow between the spaces. A formal dining room or used as a separate den provide excellent versatility, whether for entertaining, working from home, or quiet relaxation. The windowed kitchen is thoughtfully designed with granite countertops, abundant cabinetry, and premium appliances including Sub-Zero and Miele. The primary suite is bright and tranquil, featuring oversized south-facing windows, two generous walk-in closets, and a marble en-suite bath with double vanity and glass-enclosed shower. The second bedroom is equally well-sized, with its own walk-in closet and easy access to a full bath. A gracious gallery connects the public and private spaces, adding to the home’s sense of scale and arrival. Residents of 521 Park Avenue enjoy full-service living with a 24-hour doorman, fitness center, and private storage. The building is pet-friendly, permits pied-à-terres, and offers flexible financing. Designed by William Alciphron Boring and completed in 1911, 521 Park Avenue is a notable example of early cooperative living on Park Avenue. Boring, who trained at the École des Beaux-Arts and co-designed Ellis Island Immigration Station, brought a refined architectural sensibility to the building. Originally composed of full-floor residences, the building now contains a boutique collection of just 27 homes. This is a rare opportunity to own a spacious, light-filled residence that combines pre-war character, practical layout, and the enduring appeal of Park Avenue.
