Description

This exceptional and sun-drenched duplex residence occupies the top two floors of this iconic building. Entered from a semi-private landing, Apartment 11/12W immediately impresses with its sense of scale and architectural drama, highlighted by a curved wooden staircase rising toward a skylight more than 21 feet overhead. Off the foyer, the inviting library offers a warm retreat, featuring one of the apartment's six working fireplaces, a wet bar, and an adjacent powder room.

The grand living and dining rooms are designed for elegant living and entertaining, boasting 10-foot ceilings, exquisite crown moldings, two fireplaces, and sweeping west-facing views of Central Park. Flowing seamlessly from these formal spaces, the expansive chef's kitchen is outfitted with a Viking Professional range, modern appliances, and a large central island that provides ample workspace and an ideal setting for casual gatherings. Adjacent to the kitchen, a former staff room has been converted into a small bedroom with its own bath.

The second level is devoted to the private quarters. The generously proportioned primary suite enjoys western exposures over the park and southern light, and features its own fireplace and a spa-like en- suite bathroom. The second bedroom-created by combining two rooms-also includes an en-suite bath, as does the third bedroom. Each bedroom enjoys views of Central Park and its own fireplace, complemented by abundant closet space throughout. A dedicated laundry room, converted from an additional staff room, is
conveniently located on this level near the bedrooms.

Completed in 1910, 563 Park Avenue is widely regarded as the first luxury apartment building on Park Avenue. Designed by architect Walter B. Chambers, the building was conceived so that all residences facing Park appear as duplexes, distinguished by alternating window heights and an array of wrought-iron and limestone balconies. A Neo-Renaissance jewel, the property showcases a richly detailed red-brick facade anchored by a dramatic three-story rusticated limestone base. With only two residences per
floor and approximately 20 apartments total, this white-glove cooperative offers exceptional privacy and discretion. The building is wheelchair accessible, pets are permitted, a storage cage transfers with purchase, and a 2% flip tax applies.
