Description

A Full-Floor Fifth Avenue Masterpiece with Renovated Guest Suite 1E Available that could be purchased for extra.

Never before offered, Residence 2 at 845 Fifth Avenue is a rare, full-floor Fifth Avenue residence of approximately 7,500 square feet, preserved in mint, museum-quality condition and distinguished by exceptional width, impeccable proportions, and direct Central Park frontage. The offering is further elevated by a fully renovated private guest suite available, not included in this purchase prixe.

Designed by J.E.R. Carpenter in 1920, the building is among Manhattan's most refined cooperative addresses, prized for its architectural pedigree, privacy, and proximity to Central Park.

A private elevator landing opens into a grand south-facing Gallery, immediately establishing the residence's defining quality: rooms of extraordinary width and perfectly balanced proportion. Throughout the apartment, spaces feel grand yet composed, with elegant circulation and a sense of permanence.

The residence features two distinct Central Park-facing Living Rooms.

The primary "Her" Living Room, a spectacular corner space with north and west exposures, enjoys sweeping park views and is anchored by a wood-burning fireplace with a beautiful marble mantel. Over 35 feet in length, it is luminous, refined, and ideal for formal entertaining.

The secondary "His" Living Room, currently configured as a sophisticated billiards and bar salon, also faces west over Central Park and features its own wood-burning fireplace with marble surround, offering a more intimate yet equally impressive atmosphere.

Directly off the Gallery is an elegant oval Library with a discreet Powder Room, while at the opposite end of the apartment sits the enormous, monumental Dining Room-exceptional in both length and width-centered around a wood-burning fireplace with marble mantel and distinguished by a carved plaster ceiling and exquisite architectural detail. Parquet de Versailles floors, fine paneling, and original moldings remain impeccably preserved throughout the entertaining rooms.

The custom stainless-steel chef's Kitchen features top-tier appliances, a center island, and abundant storage, opening to a charming Breakfast Room. The extensive service wing includes a Pantry, Laundry Room, Gym, four Staff Rooms, and two full bathrooms-a level of infrastructure rarely found today. In addition, the apartment benefits from a separate service elevator entrance, allowing discreet staff access and seamless functionality.

The private quarters are quietly separated from the entertaining spaces. The Primary Suite features a corner bedroom with wood-burning fireplace and marble mantel, two expansive dressing rooms, and two marble bathrooms. In total, the residence comprises five bedrooms, all generously proportioned and enhanced by an extraordinary volume of custom-built closets and storage. Throughout the apartment, every inch has been thoughtfully utilized, with high-quality, fully built-in closets and storage solutions finished to the highest standards.

Included in the sale is a fully renovated private guest suite on the ground level-a true studio apartment with kitchen, full bathroom, and washer/dryer. The guest suite is adorned throughout with custom built-in closets and storage, with every inch carefully maximized and finished to the same uncompromising standard of materials and craftsmanship as the main residence.

Every material used throughout both residences is of the highest quality , selected with longevity, elegance, and architectural integrity in mind.

4 East 66th Street is a premier white-glove cooperative with full-time doorman service, private storage, and pet-friendly policies, located directly across from Central Park and moments from Manhattan's finest cultural institutions.

This is a rare, legacy-quality Fifth Avenue offering, combining scale, proportion and condition.
