The elegant carved limestone mansion at 35 East 68th Street on the Upper East Side is quite a standout, even in a neighborhood filled with historic architecture. 6sqft previously featured another duplex in the 13,000-square-foot Beaux Arts beauty that was built as a private residence for physician Dr. Edward Kellogg and grain fortune heiress Mary Dows by Carrere & Hastings, the architecture firm who designed the Frick Collection and the New York Public Library.
The landmarked mansion was converted into an eight-unit co-op apartment building, seven of which appeared on the market together last year for $34 million; but it looks like a sale never happened. Now another three-bedroom duplex is for sale, asking $3.95 million. Unlike the other listing, the home’s grand historic details are very much in evidence, from the gorgeous oak paneled living room with 14-foot ceilings to Tiffany stained glass windows and a wood-burning fireplace–complemented by a modern custom kitchen and accessible by an elevator.
