While many of us are content with our current homes and just want a comfortable living space, this isn’t true for everyone. In some places around the country, the rich want to live rich. With everything always being bigger in America, some of the houses we build are among the largest on Earth. What’s notable is that many of these homes can get as large as 20 times the size of the average American home.
So, who needs so much space? Well, it’s a good question, but with family names like Vanderbilt and du Pont, big homes were all the rage during the Gilded Age. In some cases, like the Biltmore Estate, some of these homes have been turned into museums while others are still private residences. With this in mind, let’s take a look at some of the largest houses in America in ascending order using research from sites like Explore, Family Handy Man, and Largest.org.

As this website covers plenty of topics around finance and Wall Street, it’s only right that we cover the homes of some of the biggest names on Wall Street. Unsurprisingly, many of the homes on this list have been purchased or built by those who own or run many publicly traded companies. While home prices and interest rates are going higher for most Americans, this is a look at how the 1% of the 1% truly lives.

A beautiful Victorian-style home in Briarcliff Manor, New York, Woodlea is beautiful.

Ultimately, the family’s heirs would sell the home to Sleepy Hollow Country Club, and by 1911, the house was fully converted. Between the carved wood and marble fireplaces, it remains a sight to see for golfers and non-golfers alike.
