At £400 Million This Is The Most Expensive Property Ever Listed On The Market

Last month, a Ukrainian billionaire by the name of Rinat Akhmetov made headlines when he bought up a Monaco apartment worth £408 million – the most expensive property sale ever recorded. As an off-market deal, the staggeringly pricey property was never officially listed. Meaning that though this Bel Air home comes in at a few million less at a cool £295 million ($400 million), it’s made its own mark in the history books as the most expensive property listing ever seen on the market. Take a look inside… 

Look Inside 11202 Chaldon Road

It’s always irritating when someone slips into the bathroom just as you were about to go, but with 50 bathrooms (plus nine powder rooms) to choose from, we suspect that won’t be an issue in this 39-bedroom mega-mansion. Spanning an eye-watering 70,000 sqft, 11202 Chaldon Road is closer in size to an 18th century European palace than your average Hollywood home. 

Built between 2008 and 2018, the house was designed by New York-based architect Peter Marino, best known for dreaming-up shops for Giorgio Armani and refurbishing Andy Warhol’s townhouse. Brought to life by a team of builders led by Peter McCoy, this Mediterranean Revival home is located in the Bel Air suburb of Los Angeles, perched up high on a flat eight-acre promontory with views across the Bel Air Country Club, Downton and Pacific Ocean. 

Alongside your bog-standard outdoor swimming pool, tennis courts, cinema room and home gym (yawn), this property also boasts a full spa with separate facilities for men and women, an indoor pool, a hamman, hot and cold plunges, dedicated massage suits, a Pilates studio, a beauty salon, water features and a Jeff Koons Balloon Dog installation. Suspicious of any visitors, or fearful you have a fracture? The dedicated X-ray facilities are on hand to sort all your health and security needs. 

If the ten bedrooms and 13 staff rooms in the main house don’t provide enough space for your friends, guests can enjoy their very own 30,000 sqft guest house – complete with its own kitchen, outdoor pool and gym. Meanwhile, the central 50,000 sqft residence offers up numerous living rooms, dining areas, lounges and kitchens: one for commercial and the other for family, supported by eight service and butler pantries, naturally. Or, if you prefer al fresco dining, there is a pavilion equipped with a pizza oven. And that’s not even mentioning the safe rooms, the three elevators, the laundry rooms, the art storage, the gatehouse and subterranean garage with space for 25 vehicles.

‘Properties of this calibre simply do not exist,’ says Jack Harris of The Beverly Hills Estates. ‘This is truly a once-in-a-generation asset, one that not only stands apart in the luxury residential real estate market, but also sets an entirely new global benchmark. This is the trophy property of the United States. It could never be replicated.’

For now, the property is owned by an entity linked to Qatar’s ruling Al-Thani family, which paid a mere $35 million for the site back in 2010. Today, even the annual property taxes are more than most would be able to splash out on a family home, at $1.4 million a year. 

As for whether the property will sell with such an ambitious price tag, it wouldn’t be the first to fall short of expectations. In 2024, the former home of the Rothschild family Château d’Armainvilliers in France was listed for £335 million, but sold for a measly £155 million.

To date, the most expensive home to be bought on the open market is a £240 million property in Hong Kong. The 13,854 sqft mansion was purchased by billionaire and property tycoon Pan Sutong in 2017, making it the third most expensive property to ever be sold.

While it doesn’t seem like the £408 million Monaco apartment will be ousted from top spot any time soon, if this Bel Air home sells for the asking price, it could beat out Nick Candy’s former Chelsea manor house for second place – sold in early 2026 for £270 million.
