Description

A beautifully restored and fully renovated classic residence, this elegant Park Avenue 7 room home offers 3 bedrooms, 3 windowed bathrooms, and a powder room - along with the added benefit of a maid's room, ideal as a private home office or dressing room.

Soaring 9'10" ceilings and seven floor-to-ceiling French windows with Juliet balconies fill the rooms with natural light and frame iconic Park Avenue views. The grand entertaining salon - anchored by an original marble wood-burning fireplace - is truly breathtaking and reflects the refined French architectural aesthetic of the building's early 20th-century architects. The gracious primary bedroom also enjoys a working fireplace.

Thoughtfully reimagined to honor its 1912 architecture, the apartment underwent a meticulous renovation: more than a century of paint was carefully removed to reveal and restore the original moldings, the century-old wood floors were preserved with their perfect patina, and modern comforts were seamlessly integrated. The home now features two-zone central air conditioning, new windows, a newly added powder room, a vented washer/dryer, and a beautifully designed new kitchen and baths.

Additional highlights include an oversized formal dining room, a newly renovated windowed eat-in kitchen, cedar closets, and a semi-private landing shared with only one other residence. A large private storage unit is included.

A rare opportunity to own a fully renovated prewar home that retains its historic soul while offering every modern convenience.
