Refreshed UES Limestone Mansion Rooted in Gilded Age History Seeks $65M

When railroad industrialist Henry H. Cook purchased an entire Manhattan block between East 78th and 79th Streets and Fifth and Madison Avenues, it was a key real estate move to develop what would become a much sought-after street on the Upper East Side. This limestone mansion now listed for $65 million was an early piece of Cook’s development project.

Commissioned in 1898 by self-made millionaire James E. Nichols and his wife, Lizzie, 4 East 79th Street boasts 15,200 square feet of Beaux-Arts style magnificence. Mansard roofing transports you to European streets, maintaining a Francois Ier aura throughout. The original architecture, designed by C.P.H. Gilbert, recently underwent a facelift by its most recent owner, late businessman Aso O. Tavitian. It was under Mr. Tavitian’s guidance, with help from design professionals Peter Pennoyer and Theodore Prudon, that the home blossomed anew with airiness while maintaining its original Gilded Age grandeur.

For the larger part of the 20th century, the home was used by the French Mission to the United Nations, with several apartment spaces on the upper level and no lack of space for hosting events and meetings. With a backbone for entertaining, the parlor level offers grandiose living and dining rooms, all of which are supported by the pantry’s access to both the residence and catering kitchens. Custom wood features can be seen throughout, especially in the herringbone white oak and parquet de Versailles flooring.

But, the location may be the most appealing part. Central Park views and associated natural light adorn the home, with just a moment’s walk to enjoy museums and all that the iconic park has to offer.

Serena Boardman and Susan Baker of Sotheby’s International Realty hold the listing.
