With eye-watering price tags, lavish amenities and extravagant interiors that seem almost too good to be true, the world's priciest properties were designed for those with billionaire bank accounts. From a historic palace in the heart of Cannes to a luxurious penthouse apartment in New York City, very few people could afford these dream homes. Click or scroll to step inside properties that only billionaires can buy...

As far as luxurious penthouse apartments go, this one in central Sydney is up there with the best of them. Occupying the top two floors of the Crown Residences at One Barangaroo building, this property is lavish and exclusive in equal measure. The residential skyscraper is Australia's first and only "fully integrated hospitality branded" complex and the penthouse is by far the finest unit in the building.

Stretching more than 8,600 square feet, the high-altitude home was designed by world-renowned interior design firm, Meyer Davis Studio Interiors, and is decked out with the finest materials and fixtures, like state-of-the-art appliances and gleaming marble floors. Plus, its 20-foot floor-to-ceiling windows provide complete 360-degree vistas that encompass the Blue Mountains, the Sydney Opera House and the Pacific Ocean. 

The property comes equipped with a huge double-storey living room, a chef’s kitchen, a formal dining room, six bedrooms (each with ensuite bathrooms), a home office, a cinema room, a private plunge pool, a gym and over 538 square feet of open air space across three balconies. The exceptional master suite benefits from a dream walk-in closet, twin rainforest showers and a steam room. Plus, just look at that view!

The apartment features a statement glass staircase that connects the two floors, as well as a private internal lift. What’s more, residents of the exclusive apartment complex can enjoy access to hotel-style services, including 24-hour concierge, valet parking, housekeeping and in-room dining. The residence also has plenty of resort facilities, including two pools, a six-star day spa and a tennis court, so you'd never need to leave home again. No wonder the place is listed for a cool AUD$100 million – that's £53.1 million ($66.7m).

Back in 2019, this 20,000-square-foot contemporary home in the Bel-Air neighbourhood of Los Angeles sold for £35.9 million ($45m), but now it's back on the market for a hugely inflated £59.8 million ($75m). Built over five years by diamond manufacturer, Rafael Zakaria, the property is apparently currently owned by a member of the Saudi royal family. Dirt suggests it could be His Royal Highness, Prince Saud bin Abdulaziz Al Saud, who sources say could be a direct descendent of Saudi Arabia’s late King Fahd, who was a multi-billionaire.

Designed by Tag Front Architects in 2017, the bespoke home benefits from free-flowing interior spaces finished with retractable glass doors that can be operated at the touch of a button. The doors open the rooms up to the backyard and frame jaw-dropping views of the Santa Monica skyline, the Pacific Ocean and Catalina Island. 

There's a stunning living room with a dual-sided fireplace, a kitchen custom-designed by Italian artisans, nine bedrooms and 10 bathrooms. Plus, every room is decked out with Portuguese limestone floors and Calacatta marble from Tuscany. Of course, the luxurious home is also filled with plenty of billionaire bling. There's a 20-seat movie theatre, a wellness centre, a state-of-the-art gym and a tennis court. 

The home's one-acre backyard is also home to endless viewing platforms and outdoor living spaces, as well as an incredible 250-foot infinity pool, which is one of the biggest in Los Angeles, according to Dirt.

Fans of Netlfix's Selling Sunset might recognise this glitzy mansion. It featured on season two and three of the show and at the time was the most expensive listing The Oppenheim Group had ever had. Davina Potratz was given the task of off-loading the estate, which was developed by a Russian entrepreneur. Despite being advised against it, the owner refused to sell the house for anything less than £59.8 million ($75m). That was in 2019 and it's been on the market ever since.

The newly built mansion spans just over 15,600 square feet and boasts soaring ceilings, walls of glass and meticulous attention to detail. The stylish interior includes a dramatic entrance hall, a state-of-the-art chef’s kitchen, a movie theatre, gym and wine cellar. 

The main house also offers seven bedrooms and 10 bathrooms, as well as a lavish owner’s suite with his-and-hers walk-in closets and bathrooms. There's also a separate 2,690-square-foot guesthouse with two bedrooms and two bathrooms.

Thanks to floor-to-ceiling sliding doors, every space is light-filled and offers a seamless flow to the garden. The living rooms are perfect for entertaining, while the yard is ideal for relaxation. It comes with an outdoor kitchen and dining zone, as well as one of the largest swimming pools in Beverly Hills. How's that for fancy?

Have you ever wanted to get your hands on a rare, gilded palace? Well, this one can be found in the English county of Buckinghamshire, in the quiet village of Denham. Nestled on its own 43-acre estate, the palatial property comes complete with a spectacular interior and, of course, a seriously eye-watering price tag of £75 million ($94m).

Dating back to 1688, Denham Place is considered to be one of Britain's most important country houses, according to the listing agents, Savills. Measuring a whopping 28,525 square feet, the Grade I-listed mansion was built in the classic William and Mary architectural style and was recently restored by award-winning architect Alexander Kravetz, alongside English Heritage and The Georgian Group to ensure historic accuracy – a process that took almost a decade. 

Like stepping back in time, every room is bursting with refined period details, such as 16-foot-high painted ceilings, tall sash windows, gilded accents and ornate plasterwork. There are 12 bedrooms, 14 bathrooms, 12 reception rooms and two kitchens. Yet there are also plenty of modern additions, too, including a lift to all floors, underfloor heating, integrated audio-visual systems and air conditioning. Offered fully furnished, the lucky new owner will gain all of the home's antique furnishings.

The residence has had notable former owners, too, including the Bonaparte Imperial family and the co-producer of the James Bond movies, Harry Saltzman. The mansion comes with plenty of unique extras as well, including a secret underground speakeasy with a painted barrel ceiling and a walnut bar. Plus, the property's seemingly endless gardens were designed by the iconic English landscape architect, Capability Brown. So this is no ordinary home...

Rancho Santa Fe can be found in an affluent coastal community in North San Diego County, California, and is enclosed by over 77 acres of land. Equipped with everything a billionaire could need to enjoy the ultimate outdoor lifestyle, this dreamy equestrian estate was truly made for a VIP. Let's take a closer look...

The property was designed by Marc Appleton as a luxurious horse farm and comes with a main, 15,000-square-foot residence with six bedrooms and seven bathrooms. Inside, you'll find exposed ceiling beams, tiled floors, steel framed windows and doors, gorgeous European-style fireplaces and rustic furnishings.

The ultimate VIP ranch, the estate also comes with state-of-the-art barns, including this stunning 27-stall stable. There are three sand arenas, a field of green pastures, two hot walkers, a six-horse walker, a grand prix field and private riding trails. 

The 77-acre property also benefits from a 15-acre, bass-filled lake, two detached guest houses and a six-unit apartment building, so all your friends and family could move in, too. The estate even has a private tennis court, a 25-foot lap pool and a recreation pavilion that’s home to a two-lane bowling alley. If you've fallen in love, then you'll need £79.4 million ($98.5m) in the bank in order to snap up this incredible residence.

Take one look at this mega-mansion and you'll see it's fit for royalty. Inspired by both Baroque and Rococo architecture, the mesmerising spread sits on almost three acres of land in the town of Caesarea in Israel and benefits from unbelievable views across the Mediterranean Sea. Originally listed for £201.6 million ($250m), the price was eventually dropped to the slightly more reasonable £87.9 million ($109m), but despite this, it still hasn't attracted a buyer.

Step inside the 75,347-square-foot home and you'll be dazzled by colours and refined fixtures. The one-of-a-kind property is nothing short of amazing, kitted out with natural marble, onyx mosaics, 14-karat-gold mouldings, silk carpets and custom-made furnishings. The front door opens into this grand hallway, which really does set the tone for the rest of the interior, thanks to its endless gilded surfaces, crystal chandeliers and towering marble columns.

As you'd expect, the incredible home has plenty of formal living spaces, including a 2,152-square-foot living room, a huge gilded kitchen, a formal dining room and a bar. There are a number of high-end amenities, too, including a private spa and a fitness room. Upstairs, there are five bedrooms and 15 bathrooms, while the sprawling master suite boasts not one but two ensuites, dual walk-in wardrobes and two dressing areas. 

Other luxurious amenities include a wine room, a billiard hall, a 4K movie theatre, a spectacular indoor swimming pool and eco-friendly, energy-saving systems. Outside, the grounds are a world of their own, offering landscaped gardens, two fountains with Roman sculptures and an outdoor pool with a built-in television. It's really no wonder this is one of the most expensive properties in the world.

Known as the Umm Suqeim Villa, this state-of-the-art property is situated in the heart of Dubai, United Arab Emirates, and has been meticulously crafted to cater to the owner's every whim. Priced at £100.9 million ($125.1m), the gorgeous glass house measures 22,925 square feet and comes fully furnished, so all the buyer will need to do is pack their toothbrush.

With six bedrooms, the luxe villa epitomises luxury living, combining traditional Khaleeji style with plenty of contemporary elements, including an amazing art collection by celebrated Lebanese artist, Ayman Baalbaki – in fact, the home is described by the listing agents, Christie's International Real Estate, as “Dubai's preeminent art collectors' home”.

The property was designed by Viktor Udzenija Architecture + Design and commissioned by a prominent Dubai family. A reinterpretation of a traditional Arabic courtyard house, the modern home is ultra-private, with all the rooms set on the ground floor in order to minimise exposure. However, most of the rooms open up to the exterior courtyard garden, where an illuminated pool, sunken seating area and sunbathing deck can be found.

As for interior design, the home has floor-to-ceiling windows, Italian travertine stone walls and floors, gilded bathroom tiles and even a handmade crystal dining table. There are six bedrooms, nine bathrooms, a gym, staff quarters and a 12-car underground garage. The award-winning pad was featured in Vogue Middle East, so it isn't hard to believe it comes with such an extravagant price tag.

Named Palais Vénitien, this dreamy estate is positioned moments from the azure waters of Cannes, a glistening resort town on the French Riviera. For sale via Knight Frank for a hefty €120 million – that's £103.4 million ($128.4m), the incredible property was recently redesigned by the interior experts at Cogemad, resulting in living areas overflowing with monumental columns, exquisite mouldings, gilded Venetian details and crystal chandeliers.

The historic home is considered to be one of the finest in the Cote d'Azur and its impressive interior stretches a staggering 32,291 square feet. Every single room is completely mesmerising. There are endless formal living areas – eight to be exact – as well as nine bedrooms, nine bathrooms and a seriously huge kitchen. 

Despite being extremely traditional in terms of interior design, the home has plenty of modern elements, too. The mammoth basement, for example, is akin to a private nightclub and comes equipped with a bar, a dancefloor, velvet seating and professional lighting, which makes this home a true party pad.

Outside, things are just as impressive. The six-acre parcel is home to terraced grounds that have been meticulously crafted. There's a huge swimming pool, a sunbathing deck, a tennis court, a lake and a secluded woodland. Plus, with the sandy beaches of Cannes and Antibes just down the road, the buyer will truly want for nothing.

Those with £104.8 million ($130m) going spare could snap up the penthouse inside 432 Park Avenue, a 1,396-foot-tall residential tower in the heart of Manhattan. The sky-high home sits on the 96th floor of the building and, according to the listing, "takes its premier place above every other trophy penthouse in New York".

Never before lived in, the luxurious apartment measures 8,255 square feet and benefits from soaring 12.5-foot ceilings and 24 windows that offer full panoramic views across the city. The penthouse’s private elevator opens into a 93-foot-long Great Room, which leads through to a formal dining room and a chef's kitchen with Central Park views. 

There’s also a library, six bedrooms and seven full bathrooms. The oversized primary suite offers incredible vistas, as well as two massive walk-in dressing rooms and two separate bathrooms swathed in marble.

The perfect place to take a dip, the master ensuite comes with an oval, free-standing tub that sits right in front of a full-height picture window. Plus, residents of the building get to enjoy other perks, like dining in the private on-site restaurant, sipping vintages in the wine room, or taking in a workout in the fitness centre or yoga studio. The complex also has a 75-foot indoor pool, massage rooms, a billiards room, a movie theatre and 24-hour concierge services.

Aptly named, The Manor is positioned in the Holmby Hills neighbourhood of Los Angeles and when it sold in 2019 for almost £96.8 million ($120m), the price set the record for the most ever paid for a residence in California. However, it was recently back on the market for even more. Listed for a staggering £129 million ($160m), the mansion is larger than The White House and once belonged to Formula One heiress, Petra Ecclestone, who's thought to have a personal fortune of £323 million ($400m).

It's thanks to Petra that the property now looks the way it does. She apparently overhauled the mansion in just nine weeks, with the help of 500 workers. A monochrome colour scheme runs throughout the lavish home, which boasts 123 rooms across 56,500 square feet. The incredible entrance hall looks like something from a museum and comes with a marble floor and a sweeping Cinderella staircase, while two expansive formal living rooms sit on either side of the imposing space.

The French chateau-style home sits on almost five acres of land and was originally built for the late TV show producer, Aaron Spelling and his wife Candy. As well as adding 27 bathrooms and 14 bedrooms, including a 7,000-square-foot master suite, the couple also opted to have a humidity-controlled storage room, a flower-cutting room and a gift-wrapping room. There's also a 20-seat custom movie theatre and a luxe basement with a two-lane bowling alley.

Incredibly, there's even a private beauty salon. The room originally housed Candy Spelling's doll collection, but Petra had it converted into a spa, complete with a massage parlour, three hair stations and two manicure-pedicure chairs. The brilliant backyard is just as enviable, with winding paths, immaculate lawns, a citrus orchard, koi pond, rose gardens, a swimming pool and a spa, as well as plenty of spaces for sunbathing.
