Compiling a list of the largest home in each state would make for an interesting envy-read. Thanks for a new, $10.9 million listing, we now know what Arkansas’s biggest home looks like.

Owned by Kenny King, this 18,367-square-foot estate is situated on 20 prime Natural State acres, near Fort Smith. But its most distinguishing feature is an import: a California redwood, which King had sent to his home to create the world’s greatest indoor treehouse for his grandchildren. The luxe mansion also features Italian marble fireplaces, a 106-foot-long sports bar room, and an 86,000-gallon swimming pool, with not one but two infinity edges, plus a beachlike walk-in feature. There are twinned spiral staircases in the entryway, which reportedly took workers seven months to complete, and curved, two-story back window of reflective glass, which provides a dramatic backdrop for the pool area.

“It’s truly magnificent and it’s very livable and it’s just done with such great taste,” says listing agent Marshall Yantis. “The woodwork, the molding, the details; there were some real craftsmen that performed excellent work. There’s nothing like it around this area.”

The estate is a popular site for a holiday helicopter tour of Christmas lights in the Fort Smith area. King says he puts up between 100,000 and 150,000 Christmas lights. “We do it for the kids in the area. The Fort Smith area has been very good to us.”

King, who made his dough in the restaurant business, and his wife had the house built in 2005, after deciding they liked the Mediterranean-style estates they’d seen in Florida. The eight bedroom mansion took three years to complete, and doesn’t skimp on elegant touches: inside you’ll find dramatic marble staircases and floors, Baccarat chandeliers, custom Italian mantles, impeccable trim work, a gentlemen’s card room, a 2,400 sq. ft. game room, custom theater, Otis elevator, automated smart home, gourmet kitchen, and an indoor children’s play area with the aforementioned redwood treehouse.
