Description

525 Park Avenue – Pre-War Condominium | 12 Rooms The building 525 Park Avenue is situated on Park Avenue and 61st Street, in the heart of one of the most prestigious and sought-after locations in Manhattan. 525 Park Avenue is a fabulous and impressive pre-war building designed by the world renowned architectural firm of Schwartz and Gross in 1914 and completed in 1915, in the Italian Palazzo style. The building was converted to a condominium in 1989. At that time, the developer purchased the air rights of surrounding buildings and created three beautiful penthouses with wrap-around terraces, adding to the stature of this impressive building. The Allure of Park Avenue Mall A grand-scale, 12-room corner residence, this exceptional home is surrounded by stone balconies and offers sweeping vistas of the tree-lined Park Avenue Mall in full bloom. From a private elevator landing, an elegant foyer opens into a magnificent corner living room, parlor, and expansive formal dining room all overlooking Park Avenue. Perfect for entertaining, this suite of rooms flows seamlessly, creating both a dramatic and inviting atmosphere. The private bedroom wing, discreetly situated off the foyer, is lined with closets and offers four spacious bedrooms and five full baths. The luxurious primary suite boasts two elegant bathrooms and generous custom closets, creating a true retreat. A large, windowed eat-in kitchen, accessible from the bedroom hall, features top-of-the-line appliances, abundant counter space, and a separate laundry room. Adjacent to the dining room, a handsome bar provides a refined space for serving cocktails, while a discreet powder room sits elegantly off the gallery. Designed for both grand entertaining and comfortable everyday living, this flexible floor plan adapts to every lifestyle. Should additional accommodations be desired, the renowned Regency Hotel that is celebrated for its fine dining, distinguished bar and business breakfasts is located conveniently across the street. Pre-war condominiums of this caliber are rare on Park Avenue. Ideally located in the heart of Manhattan, 525 Park Avenue places you moments from Central Park, world-class restaurants, and luxury boutiques along Madison and Fifth Avenues. This full-service building offers white-glove amenities including a doorman, concierge, and live-in resident manager. A fitness center is available on-site, with the Equinox Club and pool nearby for more extensive wellness options. Two parking garages are located within a block, and central air conditioning ensures year-round comfort throughout the apartment. Special Features • 10-foot ceilings • Major architectural detail — crown moldings and raised doorways • Central air throughout (2 zones) • Private elevator landing • Two entrances to the kitchen • Huge custom-fitted closets • Financing allowed • LL’c’s allowed • Trusts allowed • Gym • Equinox Health Center with pool around the corner • Storage • Two garages a block away
