Description

A rare opportunity to create a truly exceptional home on Park Avenue, Residence 4N at 525 Park Avenue is an opulent, grand-scale prewar condominium spanning approximately 4,000 square feet. With 12 beautifully proportioned rooms, soaring 10-foot ceilings, and elegant architectural details throughout, this expansive corner residence offers the scale, grace, and presence that are increasingly difficult to find in Manhattan. A private elevator landing opens to a gracious gallery that leads to a magnificent suite of entertaining rooms, including a corner living room, parlor, and formal dining room overlooking the Park Avenue Mall. Oversized windows and exposures to the north, south, east, and west fill the home with natural light throughout the day, while original prewar details, crown moldings, raised doorways, hardwood floors, and a wood-burning fireplace lend warmth and timeless character. The layout is both generous and flexible, with four spacious bedrooms, five full baths, and a powder room. Privately positioned off the main gallery, the bedroom wing offers a quiet retreat, including a sprawling primary suite with two bathrooms and substantial closet space. A library or den, home office, and an expansive windowed eat-in kitchen further enhance the home’s versatility for both everyday living and entertaining. While the residence retains an elegant footprint and extraordinary bones, it is ready for its next chapter. The existing finishes are dated, offering a wonderful opportunity for a buyer to renovate and reimagine the home to suit today’s lifestyle and aesthetic, all within the framework of a coveted prewar Park Avenue condominium. Designed by renowned architectural firm Schwartz & Gross in 1914, 525 Park Avenue is a distinguished full-service condominium in the heart of Lenox Hill, offering white-glove service, a full-time doorman, concierge, resident manager, fitness room, storage, and central air. Moments from Central Park, Madison Avenue boutiques, and some of the city’s best dining, this is a rare chance to bring new vision to a residence of exceptional scale and pedigree in one of the Upper East Side’s most sought-after addresses. Please contact us to view this extraordinary residence. It would be our privilege to show it you.
