Built at the turn of the 20th century for James E. Nichols and designed by C.P.H. Gilbert, 4 East 79th Street has lived several lives: private Gilded Age mansion, crime scene, diplomatic address, subdivided residence, and ultimately a painstakingly reconstructed single-family home.

Sport Island sits in New York’s Thousand Islands, the St. Lawrence River archipelago along the Canadian border that became one of the Gilded Age’s fashionable summer destinations. Built around 1880 for a prominent Pennsylvania railroad-industrialist family, the property has since undergone a substantial partial restoration.

Designed by Horace Trumbauer, whose work includes the Philadelphia Museum of Art, the Gilded Age mansion retains a four-story Carrara marble staircase, Samuel Yellin ironwork, and original Louis XV-style salon rooms across more than 10,000 ft² / 929 m².

After decades at the centre of one of Europe’s most glamorous social worlds, Beatriz Patiño commissioned a private residence of her own beside the famous Patiño Palace in Cascais, near Lisbon.
