This outrageous $250 million mansion in LA comes with a 4-lane bowling alley and an entire collection of cars

A new home built on speculation in the Bel Air neighborhood of Los Angeles is asking an earth-shattering $250 million. According to its website, it's the most expensive home ever listed in the US.

And it's certainly like no other home on the market. The mansion is built in a contemporary style, with stark geometry and huge plate glass windows.

The home also comes outfitted with furniture, but it's not your standard Restoration Hardware package. It seems it was built with a very specific person in mind: a person who likes decommissioned decorative helicopters, gigantic Leica camera sculptures, velvet-roped lounge areas, and plush decorations that were purchased from Hermés.

As for the living spaces, there are two master suites, 10 "oversized VIP" suites for guests, 21 bathrooms, three separate, fully equipped kitchens, and no fewer than five bars.

It was built by luxury developer Bruce Makowsky, whom the release refers to as the "spec king." He was also the mastermind behind the $70 million Beverly Hills house sold to Minecraft founder Markus "Notch" Persson in 2014.

"This home was curated for the ultimate billionaire who wants the best of everything that exists in life," Makowsky said in a release announcing the listing. "Until now, the ultra-luxury market was void of homes that even came close to matching the level of mega-yachts and private jets that billionaires spend millions of dollars on every year."
