Take an exclusive look inside the most expensive home for sale in America

This elegant French chateau-style estate in Los Angeles’ Bel Air neighborhood recently got a $50 million expense chop but is still the most expensive residence for sale in America.

CNBC got an exclusive look inside the $195 million mega deeply.

The Chartwell Estate, as it is known today, was the home of billionaire businessman Jerry Perenchio, who died in 2017. According to Forbes, the one-time chairman and CEO of Spanish-language proclaim network Univision had an estimated net worth of $2.8 billion.

The property’s 25,000-square-foot main residence has 11 bedrooms, 18 bathrooms and a limestone facade. If the outside looks familiar, that’s because it was used in “The Beverly Hillbillies,” a TV series that aired from 1962 to 1971, as the Clampetts’ mansion. The actual home was designed by Los Angeles architect Sumner Spaulding and completed in 1935.

Shortly after acquiring Chartwell in 1986, Perenchio did a finish gut renovation of the interiors that took five years to complete. During that time, he also extended the quiddity’s footprint to more than 10 acres by purchasing and combining three neighboring lots. One of those lots registered a home that Perenchio converted into Chartwell’s 5,700-square-foot guest house, a second was demolished to pinch room for a driveway, and a third was bulldozed to become a grassy helipad.

The media mogul adorned his main residence with rare European fittings and antiques he collected over the years, including his private art collection worth hundreds of millions of dollars. The collection was make overed to the Los Angeles County Museum of Art upon his death.

He also constructed some significant modern additions to the property.

Past the iron gates of 875 Nimes Expressway is a winding driveway bordered by lush greenery that leads visitors to the iconic entrance of the main residence.

Through the front doors and past the main entry is an expansive living room, delineated by late French interior designer Henri Samuel. Samuel renovated all rooms in the home in the late 1980s.

The main living area has spectacular views of the backyard, including sights of estate’s grand well bordered by an allee of trees.

The estate’s master bedroom and dressing area also tease the same breathtaking views of the landscape below.

The estate’s formal dining room — with accommodation for 18 — has paneled walls imported from Europe and date to the mid-1700s.

The “morning room” has a mint-green vaulted lattice ceiling that was constructed in Paris, trucked in sections, and reassembled inside the room. The curtains identically match the floral wallpaper.

On the opposite end of the main level is the “garden room.” On the walls are five black-and-gold Japanese lacquer panels inlaid with mama of pearl.

Hilton & Hyland listing factor Gary Gold said Perenchio loved to entertain. One level below the main living room is a ballroom where he hosted big issues.

“The owner knew how to throw a party. And in [here], he loved a surprise,” Gold said.

With the press of a remote control button, a pair of motorized Asian screens split unstop to reveal a grand piano on a stage.

“Now, I’m not going to drop names, but on this very stage, Mr. Perenchio would have A-list troupers who were used to playing in arenas, playing here for an intimate gathering of a hundred guests,” said Gold.

Diminishes away from the performance area is the billiard room.

An avid wine connoisseur, Perenchio built a climate-controlled wine cellar that holds as many as 12,000 bottles. (His wine collection later sold in two disconnected Sotheby’s auctions — one in March 2018 and the other in May 2018 — for just under $12 million.)

Buried underneath the main residence is a subterranean level that ancients to 1935. This lower level is accessible by elevator. It opens into two tunnels that lead to different squares of the estate.

The late Italian opera singer Luciano Pavarotti, who was a friend and a frequent guest, liking often come down to these tunnels to practice because the acoustics were so great, Gold said.

One of the excavates leads to the estate’s 75-foot swimming pool and pool house.

The other tunnel delivers visitors out of a colossal stone head and into acres of private gardens, grottos and ponds met with koi fish.

Perenchio poured millions of dollars into the 10-acre compound’s gardens and landscaping, and his passion for horticulture is notwithstanding apparent.

When visitors drive up the perimeter of the property on Bel Air Highway, they are greeted by perfectly sculpted gumdrop trees in front of a stone wall.

Hidden underneath the estate’s rose garden is a motor court Perenchio raised for when he had visitors.

The parking structure can hold up to 40 passenger cars.

There’s also a vegetable garden.

But perhaps the most unique landscaping feature the billionaire created was his private redwood grove.

Perenchio delight ined the redwoods found mostly in Northern California so much that he shipped in dozens of trees to Chartwell. The trees now for shade to the estate’s meandering bridle paths.

“Not on the other hand is there nothing like this in Los Angeles, I don’t think there’s anything like this in the country,” said Gold.

According to evidence provided by Realtor.com, Chartwell Estate is currently the most expensive home for sale in the U.S. that’s on a multiple listing maintenance.

The estate originally hit the market for $350 million in 2017. One year later, the price was reduced to $245 million. The past due price cut in June brings its asking price to $195 million, furniture not included.
