Maybe I’m being silly here forgive me, but I thought that the Biltmore Estate, built by the Vanderbilt family and featured in the movie “Being There”, was the largest home in the United States?
Technically the Biltmore now is a museum and not a residence. The Biltmore has over 150 K sq foot of living space.
It is and was, at 179k.
I think they mean the largest actually in use.
Whatever the size of Biltmore (built by George Vanderbilt) it is no longer a home but only a house.
