A newly built modern palace overlooking Los Angeles has just become the most expensive home listed in the United States with a price tag of $250 million.

CNBC has revealed that the 38,000-square-foot mansion in Bel Air, California, will officially come on the market this week — eclipsing the current record holder, a $195m mansion in Manalapan, Florida.

The home has 12 bedrooms, 21 bathrooms, three kitchens, six bars, a massage room and spa, fitness centre, two wine-champagne cellars, the most advanced home theatre in any U.S. home, and an 85-foot infinity pool.

It took more than 300 people over four years to build. And while not the largest new home listed, the Bel Air property is a marvel of technology, design, craftsmanship, exotic materials and natural views.

Bruce Makowsky, the ultra-wealthy developer who built the home and is betting a fortune on finding a buyer, said he wanted to create more than just a house. He wanted to create a “curated lifestyle” and experience that would appeal to a new class of global billionaire.

“I wanted to redefine what super-high-end luxury homes are all about,” said Makowsky, who built his first fortune from a handbag and leather goods company. “I wanted to break all the molds. The level of quality and attention to detail in this house is unsurpassed. And I wanted to create the greatest feeling that you can have being at home.”

That means that everything in the house comes with it — from the $30m worth of cars, and millions worth of fine art, to the six-figure Roberto Cavalli table settings.

When talking about the price, Makowsky said the home is more comparable to a mega yacht than a house.

“Mega yachts have gone from 150 feet to 300 feet or more and they can cost up to $500 million,” he said. “People spend two weeks a year on a yacht, but they live in a house. I wanted this to be the ultimate mega yacht, but on land.”

Here are just a few of the features boasted by the house:

  • 12 bedrooms
  • 21 bathrooms
  • Three kitchens
  • Five bars
  • Helipad complete with helicopter from Airwolf
  • 280-degree views of Los Angeles
