Description
Perched on the 10th floor of this distinguished white-glove pre-war condominium, this well-proportioned one-bedroom residence offers a smart layout, generous room sizes, and excellent separation of space. A proper entry foyer leads into an expansive living and dining room measuring approximately 25” in length, providing ample space for both entertaining and everyday living. The room faces north and enjoys soft, consistent natural light, complemented by custom built-ins. Just off the living area is a versatile home office, ideal for remote work or easily adaptable as a guest room or den. The thoughtfully designed kitchen is efficiently laid out with ample cabinetry, stone countertops, and a washer and dryer, offering both functionality and a clean, modern aesthetic. The generously sized corner bedroom benefits from east and south exposures, welcoming beautiful morning light. A dedicated dressing area, lined with multiple closets, leads to the bathroom. With abundant closet space throughout, excellent proportions, and a layout that balances privacy and functionality, this home offers comfortable and refined living in a classic setting. 525 Park Avenue is a premier 14-story pre-war condominium designed by the renowned architectural firm Schwartz & Gross and completed in 1915 in the Italian Palazzo style. Ideally situated on Park Avenue at 61st Street, in the heart of one of Manhattan’s most prestigious and sought-after neighborhoods, the building offers full-service white-glove amenities and a level of privacy rarely found on Park Avenue. Residents enjoy immediate proximity to Central Park, as well as the city’s finest restaurants, cafés, boutiques, galleries, and world-class museums. The building is also notably flexible, permitting financing, LLC ownership, and purchases in trust. There is a Working Capital Contribution equal to one month’s common charges and real estate taxes payable by the purchaser. Apartment 10C is also available for sale and could be a wonderful opportunity for a buyer seeking additional space.
