Biltmore House was designed by architect Richard Morris Hunt and is America's Largest Home® spanning 175,000 square feet, which is more than four acres of floor space. The 250-room French Renaissance chateau includes 35 bedrooms, 43 bathrooms, and 65 fireplaces.

The Biltmore House in Asheville, North Carolina, contains a total of 35 bedrooms. As the largest privately-owned residence in the United States, this French Renaissance château encompasses a staggering 250 rooms across four floors and a basement. Beyond the 35 bedrooms, the estate features 43 bathrooms, 65 fireplaces, and three kitchens. Many of the bedrooms are located on the second and third floors, showcasing the opulence of the Gilded Age with original 19th-century furnishings and intricate tapestries. While a standard self-guided tour allows guests to see about 85 rooms, specialized tours in 2026—such as the "Backstairs Tour"—provide access to the more secluded guest quarters and domestic staff rooms. The sheer scale of the house, which covers four acres of floor space, was designed by George Vanderbilt to host lavish house parties for the era's social elite, ensuring that every guest had a private and luxurious retreat.
