This sprawling beachfront pad was built in 1930 by architect Maurice Fatio, who was famous for his luxury, Mediterranean-style mansions. The previous owner, billionaire Jim Clark, put it on the market back in 2016 for $137 million (£104m). Without a sale, he was forced to slash the asking price to $115 million (£87m) and in 2018 eventually sold it for around $90 million (£68m) to the Vecillio family. 

A Maltese-inspired mansion, Villa Vittoriosa, is reported to be the biggest family residence in the state of Georgia. The former home of boxer Evander Holyfield is housed within an estate which includes a 4,000-square-foot guest house and a seven-stable barn. The home was reportedly bought by hip-hop artist Rick Ross in 2014 for $5.8 million (£4.4m). 

The grand entrance hall features an impressive marble floorwork design which extends from the centre of the room. Dual staircases lead down from the balcony, surrounded by gold-embellished Roman-style pillars. It really is one of the most luxurious homes in the world! 

Le Palais, a palatial chateau-style mansion, was designed by developer Mohamed Hadid, father to supermodels Bella and Gigi. The billionaire-worthy backyard surrounding the limestone property features olive trees, fountains, four rose gardens and a pond that's home to a flock of swans.

There are seven bedrooms, with the master suite hosting two of the house’s 11 bathrooms. In one of the wash spaces, there's even a secret staircase worthy of a spy movie that leads up to a rooftop garden. Downstairs, a home gym and spa rooms open out onto the verdant gardens, where cabanas surround a 60-foot infinity swimming pool.

One of America's most amazing estates, Asherwood stands within 107 acres of land with an 18-hole golf course, tennis courts and two swimming pools. Located in Carmel, Indiana, the property was owned by the late US shopping magnate Mel Simon. In January 2018, Simon's widow gifted it to the Great American Songbook Foundation, who have now put it on the market at an undisclosed price. 

Outside, the secluded courtyard with its vibrant, Mediterranean-inspired colour scheme is perfect for alfresco dining. For sport-lovers, there's the choice of a hard indoor tennis court or an outdoor clay court, as well as a bocce court and a variety of horse facilities, making it the perfect equestrian property too.

The Manor was built in 1988 by Aaron and Candy Spelling and is one of the grandest private residences in the world. Sitting on nearly five acres of land in Holmby Hills, the recently renovated mansion borders the LA Country Club. Once the most expensive home ever sold in Los Angeles County, it was purchased by Canadian billionaire Daryl Katz for $120 million (£90.9m) from its previous owner, Petra Ecclestone, in an all-cash deal.

Formally known as Le Palais Royal, this mega-mansion in Florida is one of America's most expensive homes, having been listed for $159 million (£120m) in 2016. Located in Hillsboro Beach, the mansion was modelled on the Palace of Versailles. However, after languishing on the market for some time, the property was finally sold for $42.5 million (£32m) in 2018. Despite being significantly lower than the original listing price, it was reportedly the highest price a US home has ever sold for at auction at the time.

With such provenance, it'll come as no surprise then that the house is decked out in the most luxurious materials imaginable. The entrance features a marble staircase with wrought-iron railings and gold-leaf accents that took two years to finish at a cost of $2 million (£1.5m). The gold leaf doesn’t stop there, as the mahogany kitchen cabinets are also adorned with the opulent finish.

The extravagant house has 11 bedrooms and 17 bathrooms, with four of the bathrooms offering luxurious Jacuzzis – the perfect vantage point from which to admire the home's 465 feet of beachfront or even keep an eye on your yacht in the private dock. 

Outside, the mansion is just as fabulous. A 4,500-square-foot infinity pool with six cascading waterfalls is complemented by an LED-lit waterslide. Meanwhile, a firepit sits in the middle of the pool and suspended above on a plinth is an infinity-edge hot tub. And that’s not all – the house is also reportedly home to the world's first residential 3D IMAX theatre. Definitely one of the most jaw-dropping home features money can buy! 

Entering the property is like stepping into a time warp home. The tapestry-draped walls of the grand hall are made of stone, while marble archways open out into various reception rooms. A vast staircase leads up to the first floor, which C. Ledyard Blair and his family used as their living area.

This beautiful 15-acre estate sits on a private barrier island in Manalapan, Florida between the Atlantic Ocean and Lake Worth. Perched on top of a dune with 360-degree views of the water, the property is currently on the market for $115 million (£87m).

Home to one of the world's most famous families, Biltmore in North Carolina was built for George Washington Vanderbilt II in the late-19th century. The colossal Gilded Age mansion, which is still owned by descendants of the Vanderbilt family, sprawls over 175,000 square feet.

The gigantic house, which was modelled on the Château de Blois in France's Loire Valley, was built over a six-year period by thousands of workers and features more than 250 exquisitely decorated rooms. The epic mansion is now open to the public 365 days a year.

The largest room in the house, the medieval-style banquet hall seriously wows with a towering, seven-storey ceiling, intricately carved wooden panelling and a vast dining table that seats up to 30 guests. 

Vanderbilt travelled throughout Europe and Asia collecting fabulous antiques and paintings for his country home. Needless to say, Biltmore is a treasure trove of art and works by the likes of Renoir and Sargent hang on its walls, as well as a selection of breathtaking 16th-century tapestries. It's definitely the biggest house in America and it's arguably the best!
