Description

Entire 15th Floor - High Above Park Avenue

Presenting a rare opportunity to own an expansive and beautifully appointed full-floor residence in one of Manhattan's most distinguished prewar cooperatives. Located at 1088 Park
Avenue, Apartment 15A is a sophisticated eight-room home (originally nine rooms) that seamlessly combines the elegance of classic prewar architecture with modern comfort and convenience.

Flooded with natural light from oversized windows facing north, south, east, and west, this gracious residence enjoys tranquil views of tree-lined streets and the building's private garden, offering remarkable privacy and serenity in the heart of Carnegie Hill.

A private elevator landing opens into an impressive entry gallery, creating a welcoming introduction to the home's generous proportions. The gallery flows seamlessly into an oversized, sun-filled corner living room anchored by a charming wood-burning fireplace. Ideal for both grand entertaining and relaxed everyday living, this inviting space exemplifies classic New York elegance.

Adjacent to the living room is a formal corner dining room overlooking the building's beautifully landscaped garden-an unexpectedly peaceful retreat from city life. The thoughtfully designed eat-in chef's kitchen is both stylish and highly functional, featuring extensive cabinetry, top-of-the-line appliances including a Viking six-burner range, Sub-Zero refrigerator, and Miele dishwasher, as well as a Miele washer and dryer. A generous breakfast area comfortably accommodates four, with additional corner seating. A butler's pantry further enhances both storage and service.

The separate bedroom wing offers a quiet and private sanctuary. The bright primary suite features custom built-ins, excellent closet space, and a windowed en-suite bathroom. Two additional generously sized bedrooms each have newly renovated windowed baths.

Near the foyer, a versatile fourth bedroom-currently configured as a library/den-offers flexibility for work or relaxation. An office, located near the kitchen and outfitted with custom bookcases, built-in storage, and a marble desk, is served by another full windowed bathroom.

Throughout the residence, elegant prewar details abound, including high ceilings, hardwood floors (herringbone in the living room), crown moldings, and custom built-ins. Abundant storage, including walk-in and linen closets, adds to the home's exceptional functionality.

Designed by renowned architect Mott B. Schmidt, 1088 Park Avenue is among the most coveted cooperatives on the Upper East Side. Residents are welcomed by a recently renovated lobby and a dramatic double-height entrance vestibule. The building also features a nearly quarter-acre private garden with seasonal plantings and a tranquil fountain.

White-glove services include a full-time doorman, private storage, bicycle storage, and two newly renovated fitness centers. The cooperative has also recently acquired a ground-floor professional space that will be converted into an additional future amenity for residents.

Ideally situated moments from Central Park and the cultural institutions of Museum Mile, the building enjoys convenient access to the finest dining, shopping, and schools the Upper East Side has to offer.

Apartment 15A represents a truly exceptional opportunity to experience classic New York living at its finest.
