SPECTACULAR BEAUX-ARTS LIMESTONE MANSION
A Rare Opportunity to Acquire a 1901 Gilded Age Masterpiece
Nestled just off Fifth Avenue's prestigious Gold Coast, this approximately 18,000-square-foot Beaux-Arts limestone mansion is a once-in-a-lifetime offering. With six above-grade floors and two below-grade levels, this architectural treasure is one of the few remaining mansions of the Gilded Age in Manhattan
Behind its commanding limestone facade lies an array of extraordinary rooms with soaring ceilings, exceptional proportions, and an abundance of irreplaceable original architectural details. Highlights include a majestic marble staircase, a copper-balconied landing overlooking the parlor, intricately coffered ceilings, and exquisite period moldings throughout.
Designed in 1901 by John H. Duncan, one of America's preeminent architects of the era, the mansion exemplifies his timeless craftsmanship. Duncan is celebrated for landmark projects such as General Grant "s National Memorial (1897) overlooking the Hudson River and the Soldiers" and Sailors" Arch in Brooklyn's Grand Army Plaza. His influence resonates in every corner of this magnificent home.
