4. 680 and 684 Fifth Avenue Townhouses
William Henry Vanderbilt’s other two daughters – Florence Adele Vanderbilt Twombly and Eliza Osgood Vanderbilt Webb – weren’t too far away from their sisters. In fact, they were neighbors. Florence and Eliza’s Fifth Avenue townhouses were designed by architect John B. Snook and though close in proximity to the “Triple Palaces,” they looked very different. As opposed to the boxy shape of the Triple Palaces, the Snook-designed homes had varied rooflines with multiple domes and gables and the facades boasted bay windows and a spattering of turrets. Florence moved out of her home in 1926 and Eliza sold hers to John D. Rockefeller in 1913. A skyscraper stands in their place today.
