Biltmore Estate, North Carolina

The Biltmore Estate in Asheville, North Carolina, is the largest home in the U.S. and comes in at a staggering 175,000 square feet. That’s nearly 70,000 square feet more than the next biggest home in the U.S.

The estate was built for the Vanderbilt family, which built its fortune through railroads, and had 35 bedrooms, 43 bathrooms and 65 fireplaces. It was officially opened in 1895, six years after construction started. In 1930, the estate opened to the public and is now the top tourist attraction in Asheville.

Living there must have been like living in one of these 50 incredible castles.

Otto Kahn built the 109,000-square foot Oheka Castle on Long Island from 1914-19 for a cost at that time of $11 million, roughly $158 million in today’s dollars. Kahn was a financier whose work included reorganizing railroads.

Now a luxury hotel, the castle includes a golf course and used to have a private airstrip. Exterior shots of Oheka Castle even appeared in the classic film “Citizen Kane.”

Gray Towers Castle, Pennsylvania

Modeled after medieval Alnwick Castle in Northumberland, England, Gray Towers Castle was built for sugar magnate William Welsh Harrison and designed by architect Horace Trumbauer.

At 66,341 square feet, Grey Towers s the 18th largest house in the U.S. The castle became part of the Arcadia University campus in 1929, and its once-regal bedrooms are now used as student housing!

Winterthur, Delaware

The third-largest home in the U.S. is in one of the smallest states, Delaware. Clocking in at 96,582 square feet, Winterthur was built for the du Pont family and was completed in 1932.

Avid art collector and horticulturist Henry Francis du Pont donated the mansion and collections to the state in 1951. It’s now the Winterthur Museum, Garden and Library, and houses one of the most important collections of early American arts and crafts. The museum is spread over 175 period-rooms and sits on nearly 1,000 acres of grounds and naturalistic gardens.

Pensmore, Missouri

This 72,000-square foot behemoth was constructed as a tornado-proof, bomb-proof, earthquake-proof home. It’s built with insulated concrete form and called Chateau Pensmore. It’s located near Ozark, Missouri and Steven Huff, an astrophysicist, built it to withstand an EF-5 tornado with reinforced steel referred to as helix, into the concrete, which should bend rather than break in the event of a tornado. For a more practical solution to prepare for a tornado, try researching a storm shelter.

The One, California

Iconic Hearst Castle used to top the list of California’s largest homes, but it’s been usurped. The One, a newly-completed 100,000 square-foot mega-mansion built by real estate mogul Nile Niami, is expected to sell for at least $340 million. That will make it the U.S’s largest and most expensive home.

With its futuristic design, The One will feature 20 bedrooms, 30 bathrooms, and five swimming pools, plus a movie theater, 50-car garage and a private nightclub!

You can add square footage to your house, just maybe on a smaller scale.

The Breakers, Rhode Island

Another project of the Vanderbilt family, The Breakers in Rhode Island measures 62,482 square feet. The Italian Renaissance-style home features marble imported from Italy and Africa.

The 70-room mansion became a National Historic Landmark in 1994 but until recently, heirs of the Vanderbilt family lived in a third-floor “apartment” (the third floor is actually eight bedrooms). Today, the estate is the most-visited tourist attraction in Rhode Island.

Meadow Brook Hall, Michigan

Matilda Dodge Wilson, the wealthy widow of automotive giant John Dodge, and her second husband, Alfred Wilson, built this 88,000 square foot home in the Rochester Hills area north of Detroit.

Constructed between 1926 and 1929, the Tudor revival-style residence has 110 rooms, sits on 1,500 acres and cost nearly $4 million at the time it was built. Today it’s part of Oakland University and is still filled with much of the Wilsons’ priceless art collection.

Stan Hywet Hall and Gardens, Ohio

There’s a lot of money in tires. Goodyear Tire and Rubber Company co-founder F. A. Seiberling built this sprawling country house for his family in Akron, Ohio.

Built between 1912 and 1915, the home was modeled on English country estates—its name is an Old English form of “stone quarry”, in homage to the former quarry it was built on. In the 1950s, the surviving Seiberling children donated the house to a non-profit, which now runs it as a historic mansion museum.

Castle Hill, Massachusetts

Castle Hill, a 56,881-square-foot  Stuart-style mansion sits on the 2,100-acre Crane Estate in Ipswich, Massachusetts, on a site whose history is linked to the arrival of the first British colonists.

The Crane family gained wealth from manufacturing brass goods and plumbing supplies and bought the property, which included five miles of shoreline, in 1910. The family donated much of the property to The Trustees of Reservations in 1945 and today it’s open for tours.

Nottoway, Louisiana

Down in Louisiana, this plantation house built in a Greek Revival style covers 53,000 square feet and dates back to 1859. John Hampden Randolph, a sugar planter, had the home built and made sure that it would remain a one-of-a-kind home by destroying the plans following its construction. It’s now a luxury hotel and a popular wedding venue.

Before you do any work to your home make sure you pick out a contractor who will follow the plan to a T.

Chateau Montagel, Alabama

Chateau Montagel was a dream home for Larry House, the former CEO of a medical supplier, MedPartners, in Alabama. The 54,400-square foot home on 27 acres was built in 1997, with historic French and Italian castles in mind.

It took four years to build and includes some quirks. The driveway is shaped like a guitar, there’s a commercial elevator and a theater with a 170-inch screen. The home last sold for $4.8 million in 2017, well below its $12 million assessed value.

15 / 50

Hala Ranch, Colorado

The 95-acre Hala Ranch in Colorado boasts 56,000 square feet and 15 bedrooms in the main house, overlooking the Rocky Mountains. It once held the distinction of being the most expensive property in the U.S. when it had a price tag of $135 million in 2006.

John Paulson, a hedge fund billionaire purchased the ranch in 2012 for $49 million from Saudi Prince Bandar bin Sultan, a former ambassador to the U.S. Bin Sultan bought the land for the house in 1989 and completed the house two years later.

The property has its own wastewater treatment plant and we’re not talking a septic tank, though you might be surprised to know how a septic tank works.

Chase Mansion, Connecticut

Arnold Chase’s mansion in Connecticut contains a 33,000-square foot basement that features a 103-seat movie theater, ticket booth, concession stand, game room and a music room, according to an Associated Press story. That basement holds much of the total 51,000 square feet of the mansion.

Get out of the basement and bring the theater outside so you can feel fancy, too.

1299 Via Tivoli, Nevada

The total square footage of 1299 Via Tivoli in Henderson, Nevada is just under 40,000 square feet. It was completed in 2010 for eBay founder Pierre Omidyar and has 25 bathrooms, 33 bedrooms as well as two exercise rooms. There is also a 35-foot climbing wall, a vast pool and a racquetball court. Oh, there is space to fit 10 people for dining … in the wine cellar.

We’ve got a pretty neat idea of where to keep your wine stash.

Oak Hall Cobe EstateCourtesy of Fernando Maclen

Oak Hall, Maine

The property, referred to as Oak Hall, Cobe Estate and Cariad, has sat on the shores of Penobscot Bay in Northport, Maine, since 1913. It was designed by Marshall & Fox as a summer home for Ira Cobe. It was added to the National Register of Historic Places in 1983.

The 20,000-square foot home and 13-acre lot sold for $1.84 million in June 2020, according to Zillow.

Chateau Bray, Texas

This one is kind of depressing.  While 60,000-square foot Chateau Bray in Manvel, Texas doesn’t look so great from the outside, the interior is even worse — it’s 46 bedrooms and 36 bathrooms are completely empty.

Houston doctor Ulysses W. Watkins started building two mansions in Manvel, Texas, outside of Houston, but one was never completed. The house has changed hands a few times but is still a work in progress.

Make sure you know the zoning and building codes before you start building a mansion.

Springville, Utah

Built in 2010, this 49,568-square foot home set on 75 acres in Utah has a measly six bedrooms and 12 bathrooms. There’s also an indoor pool with a waterfall, an indoor shooting range and an indoor basketball court, making this a year-round playground for sporty types. It last listed for $35 million, but no word on the final sale price.

Xanadu 2.0, Washington

It’s no surprise that the largest home in Washington State belongs to Microsoft co-founder Bill Gates and his wife, Melinda.

Their 66,000-square-foot, Pacific-lodge style retreat just outside Seattle is named Xanadu 2.0. As you’d expect, it’s smart-wired throughout, with its own server, an indoor pool with an underwater sound system, and a 2,500-square-foot gym.

Illinois Governor’s Mansion

As the name suggests, the Illinois Governor’s Mansion is the governor’s residence in Springfield, Illinois. Constructed in 1855, it’s the third-oldest governor’s residence in the U.S. and draws on the Classical Revival style for its 45,000 square feet. It’s gone through several renovations and is currently the home of Governor J.B. Pritzker, though the public is allowed to visit.

Marland Mansion, Oklahoma

Oil baron E.W. Marland once controlled ten percent of the world’s oil supply. He wanted to build a palace to reflect his vast wealth, and that’s what he did at Marland Mansion in Ponca City, Oklahoma.

Built in the Mediterranean Revival style, the 43,561-square foot mansion includes 55 rooms, ten bedrooms, 12 bathrooms, seven fireplaces and a kitchen for each meal. Normally, we’ve got trouble fitting everything into our kitchen. The mansion is now a museum of art and architecture.

Asherwood, Indiana

Mel Simon, who once owned the Indiana Pacers basketball team, built this 51,267-square foot home in 1999. It included its own 18-hole golf course on the 106 acres in Carmel, Indiana. In 2017 Simon’s widow, Bren Simon, donated the estate to a performing arts center, which plans to use it to house the Great American Songbook Hall of Fame Museum.

Full golf course in your backyard? Probably not, but maybe a putting green. Check out 19 crazy backyard putting greens.

Walker McCune Mansion, Arizona

Once home to Hormel Foods heir Geordie Hormel, this 52,000-square foot home once cost him $11,000 a month for electricity. The home takes its name from Penzoil heir Walker McCune, who built it in the 1960s.

It includes a 150-seat theater, an Olympic-size swimming pool and a beauty salon. Hormel died in 2006 and the home took quite some time to sell. Zillow currently values it at $8.1 million.

26 / 50

North Wales, Virginia

North Wales is on the market once again. The 38,500-square-foot stone manor house dates back to 1776 and has been thoughtfully expanded during the last few decades.

Listed on the National Register of Historic Places, the 1,471-acre property is for sale again — it’s now listed at $29.95 million.

27 / 50

Norton Manor, Maryland

Once the largest home in Maryland, the Government House in Annapolis has been bumped off its pinnacle by Norton Manor, a 47,000-square-foot modern mansion in Potomac, Maryland.

Home to philanthropists Frank Islam and Debbie Driesman, the 14-bedroom, 23-bathroom estate was completed in 2013 and has hosted President Joe Biden — appropriate, since the design was inspired by The White House.

28 / 50

Longview Estate, New Hampshire

On its own private promontory on New Hampshire’s Lake Winnipesaukee, Longview Estate’s combined 63,000 square feet make it the Granite State’s largest.

Built by New Hampshire International Speedway founder Bob Bahre and his wife, Sandra, the main house has seven bedrooms, 16 bathrooms, 15 fireplaces, and two elevators. It once listed for $49 million but sold in 2019 for a paltry $5.6 million. Times are hard!

Stowe, Vermont

It won’t just be the square footage of this Vermont home that will knock you out. The 8,150-square foot home owned by former beer distributor Stephen Levin is filled with American folk art.

Outside on the 85 acres are go-karting trails, a miniature golf course and a zip line. The downside, the ½-mile driveway to the main gate and then up another road to get the mail. It’s on the market for $12 million.

30 / 50

Fayetteville, Georgia

This Georgia house is large enough to house the heavyweight champion of the world and the ego of a rapper. The Fayetteville, Georgia home that tops 44,234 square feet, has 109 rooms and two swimming pools.

It’s now owned by rapper Rick Ross and before that it belonged to Evander Holyfield. Ross bought the property for $5.8 million back in 2014. In late 2020, he purchased another 87 acres next door — maybe to build a guesthouse?

31 / 50

Bloomfield Place, Kentucky

Bloomfield Place in Lexington, Kentucky comes in at 24,252 square feet on 11 acres. The construction took place from 1997 to 2000 and used Indiana limestone to construct the five-bedroom, five half-baths, five full-baths, a 900-square foot kitchen, a home theater and much more. It last sold for $4 million.

32 / 50

Ramsey Mansion, Mississippi

Financier J. Edgar Monroe built this Mississippi home back in 1963 as an 11,000-square-foot ode to his Gatsby-style home in Rhode Island. The footprint of the home expanded by more than double to 25,000 square feet after Charles Ramsey bought it in 1993.

He added two wings to the house to make it a 15-bed, 19-bath mansion on 8 acres. Now for the bad news. The home, named the Ramsey Mansion, was struck by lightning in 2019 and completely destroyed. The lot is now for sale for $4.5 million.
