Description

Sun-Filled Prewar 3BR with Juliet Balcony on Park Avenue

Bathed in beautiful southern and western light, Apartment 9W is an elegant 3-bedroom, 2.5-bath prewar residence offering classic proportions, gracious entertaining spaces, and a charming Juliet balcony overlooking the Park Avenue Esplanade.

Accessed via a semi-private landing, the home opens into a welcoming foyer and central gallery that set the tone for the residence's timeless character. Nearly 10-foot ceilings, oversized windows, hardwood floors, and refined architectural details create a warm and sophisticated atmosphere throughout.

The expansive corner living room is flooded with sunlight from multiple exposures and features a wood-burning fireplace and access to a lovely Juliet balcony - a rare and inviting feature that brings in fresh air and greenery from Park Avenue below. Adjacent to the living room, the generously scaled formal dining room offers an ideal setting for both everyday living and entertaining.

The thoughtfully designed kitchen features excellent storage and workspace, stainless steel appliances, and an in-unit washer/dryer.

Privately situated away from the entertaining rooms, the bedroom wing offers a comfortable and functional layout. The primary bedroom enjoys beautiful light, generous closet space including a walk-in closet, and an en-suite bath. A second well-proportioned bedroom sits nearby, while the third bedroom is ideal as a guest room, nursery, or home office.

Built in 1908 and designed by Pollard & Steinam, 863 Park Avenue was the first residential building constructed on Park Avenue above 57th Street. With only 25 residences and two apartments per floor, the cooperative offers an intimate and distinctive old-world ambiance rarely found today. Amenities include a full-time elevator operator, resident manager, bicycle room, laundry room, and private storage cage that transfers with the apartment.

Perfectly positioned moments from The Carlyle, The Mark, Sant Ambroeus, Madison Avenue boutiques and restaurants, world-class museums, top schools, and Central Park, Apartment 9W offers quintessential Upper East Side living.

The building is pet friendly, permits pieds-à-terre, allows up to 50% financing, and there is a 3% flip tax.

Please note there is an ongoing assessment of $406.26/month through October 2029 to replenish the building's reserve fund.
