Since then, it’s passed through the hands of many elite owners and has also been used as a film set for Alfred Hitchcock’s “La Main Au Collet” (To Catch a Thief).
When Lebanese-Brazilian banker Edward Safra, its previous owner, passed away in 1999, he left the villa to his wife, Lily Safra (nicknamed ‘The Gilded Lily’).

4. Villa Les Cèdres, France
Built roughly around 1830, the 18,000-square-foot Villa Les Cèdres (named after the many surrounding Cedar trees) is more of a luxury palace than it is a simple home. Set across 35 acres of land in Saint-Jean-Cap-Ferrat in the South of France, this historic luxury mansion is fit for a king—and was once owned by one, King Leopold II of Belgium.
The century-old luxury mansion was acquired in 2016 by Italy’s Campari Group (who owned the property through its acquisition of the liqueur Grand Marnier) and sold to Ukrainian billionaire and businessman Rinat Akhmetov in 2019.

Possibly the most extravagant home on the French Riviera, the Palais Bulles or, Bubble Palace is a little different from your ordinary million-dollar house. As its name suggests, this luxury property in Théoule-Sur-Mer near Cannes is shaped like a huge, terracotta-colored bubble. A bird’s eye view at the Palais Bulles reveals a collection of circular buildings. And the circle theme continues inside.

The luxury villa was designed by Hungarian architect Antti Lovag and features ten suites decorated by different contemporary artists. As well as the series of round rooms, this luxury mansion is also home to a sprawling, open-air 500-seat amphitheater on the hillside grounds, with views overlooking the Mediterranean sea.
The Bubble Palace was last owned by the late French fashion designer Pierre Cardin who acquired the historic mansion in 1992 as a luxury holiday home and has been the backdrop for many a fashion and celebrity event.

One of the most elite streets in the UK, the whole of Kensington Gardens is known for being full of millionaire properties, but 18-19 Kensington Gardens takes things a little further. Known as Nour Palace, this neo-Georgian mansion was bought in the 1990s for five million dollars.
Years of restoration—and a $90 million investment—turned it from a derelict, half-put-together house into a millionaire’s dream, with a value that’s grown exponentially. Stunning rooms come complete with traditional charm, with manicured gardens around the entire property to be enjoyed on warm spring days. A lot of the luxury property owned by Indian steel magnate Lakshmi Mittal was renovated using the same marble as that used to build the Taj Mahal (hence the mansion’s nickname Taj Mittal).

Looking onto Malibu’s coastline, the behemoth property sprawls over 30,000 square feet and cost the music moguls $200 million (a “bargain” considering the house was initially listed at $295 million).
But it isn’t just the real estate’s prime location (high above Paradise Cove, with unobstructed ocean and coastline views) and extraordinary size that is responsible for such a price tag; it’s also the home’s world-class architectural pedigree.

This is the most expensive house sold, to date, in Florida. A company controlled by software billionaire and Oracle founder Larry Ellison bought the ocean-to-lake estate at 2000 S. Ocean Blvd. in Manalapan from a trust controlled by Netscape co-founder Jim Clark.
Jim Clark initially bought the estate and parts of nearby Bird Island only two years earlier for a combined price of $94.37 million. Adding an extra $100 million in only two years makes it a handsome investment.

But it was also The One riddled with debt and legal issues.
The One was listed for $295 million in auction in January 2022—making it the most expensive home for sale in the US at the time—but was finally sold for US$141 million in March 2022 to Richard Saghian, CEO of fast fashion company Fashion Nova. Despite its flaws, this is a beautiful luxury property with gorgeous views in a breathtaking setting. Sitting on nearly four acres of land in the exclusive neighborhood of Bel Air, the 105,000 sq ft luxury mansion is said to be America’s largest private residence.
