Loft-Like Prewar Condominium on Park Avenue

Rarely available, this sun-flooded 1-bedroom, 1.5-bath residence sits on a high floor of one of Park Avenue’s most distinguished prewar condominiums. Spanning approximately 1,000 sqft, the home is defined by its soaring 10’8” ceilings, oversized windows, and open city views that create a bright, airy, and loft-like atmosphere.

The gracious layout features a spacious living and dining area with excellent proportions, ideal for both entertaining and everyday living. With its scale and flexibility, the residence can be easily reimagined as a comfortable two-bedroom home, offering exceptional versatility.

The private wing includes a generous bedroom suite with excellent closet space, an en suite bath, and an additional powder room. A windowed kitchen adds to the home’s appeal, enhancing both functionality and natural light throughout.

521 Park Avenue is a white-glove prewar condominium offering 24-hour doorman, porter, handyman, live-in resident manager, and fitness center, with laundry and private storage in the basement. Pets, pied-à-terres, and flexible financing are welcome. Ideally located near Central Park, Madison and Fifth Avenue shopping, and world-class dining, this address offers the very best of Manhattan living.

Currently the unit does not have a washer/dryer, but it has been approved by the building and easy to install.
