There’s a reason the Biltmore House near Asheville, North Carolina is dubbed “America’s Largest Home®” (and yes, that is actually a registered trademark of the Biltmore company).
Constructed by George Washington Vanderbilt II between 1889 and 1896, the Biltmore House sits on the 10.86 square mile Biltmore Estate. It has 135,280 square feet of living area and because it is still owned by Vanserbilt’s descendants, that makes it the largest privately owned house in the United States.
Descendants of Vanderbilt include noted eye-roller and CNN news anchor, Anderson Cooper and star of TV’s Deadwood and Justified, Timothy Olyphant.
