In recent years, there's been a sharp increase in the number of $100 million (£76m) properties being built for the super-rich—just when we think we've seen the most extravagant billionaire mansion, another crops up that blows it out of the water. From opulent residences with nightclubs and recording studios to palatial private island retreats, these high-end homes are only available to the world's elite.

In September 2020, this oceanfront estate landed on the real estate market for $100 million (£75m). Owned by Irish actor, Pierce Brosnan, the Thai-inspired pad is one of the most expensive celebrity homes and boasts 13,000 square feet of lush interior space with amenities that are worthy of a five-star resort. Despite this, it was reported that Brosnan was struggling to sell the property, and it is now no longer on the market.

Built in 2010, after the James Bond actor snapped up two lots of land to turn into his longtime home, the mansion sits behind carved teak entrance gates. Finished off with the finest materials, the sophisticated resort-style property boasts panoramic ocean views from almost every room.

Inside, the open-plan layout is filled with natural light and features wide-plank teak floors, scissor truss ceilings and floor-to-ceiling windows throughout, making the perfect relaxing beach house. Five bedrooms and 14 bathrooms sit alongside a stylish chef's kitchen with a butler's pantry and a temperature-controlled wine room, that's perfect for entertaining. With a recording studio, screening room with a bar, and a gym, there's always something to keep you occupied in the plush house.

The outside is just as impressive and sits on over an acre of land that offers everything you could want and more. An art studio and a two-storey pool house only add to the relaxing vibes of the saltwater swimming pool, landscaped grounds and spa. With 177 feet of private beachfront, it really is the ultimate $100 million (£76m) home.

This wasn't just a $100 million (£76m) property, it was an entire island for sale. Great Island is the largest private island ever to be on sale on the East Coast, according to Realtor, and the 60-acre land mass is bordered by more than a mile of shoreline on the Long Island Sound.

This is no desert island though, and comes with a beautiful three-bedroom stone house, dating back to the early 1900s and spanning 13,000 square feet. The island also features a 19th-century farmhouse, a seaside bungalow and a beach cottage, totalling 10 bedrooms across the isle.

World-class equestrian facilities include a timeless, 18-stall granite stable, indoor and outdoor rings, a polo field, paddocks and plenty of trails for testing your riding skills.

Great Island was initially listed for the price of $120 million (£91m) in 2018, but the listing was then removed in 2019. It was then placed back on the market in early 2022 as one of the most dazzling $100 million (£76m) offerings in this round-up, and was quickly snapped up. 

With its white columns and grand porticoed entrance, you might well believe that this impeccable mansion on a tree-lined street in the salubrious neighbourhood of St John’s Wood was a relic from a bygone century. But this custom-built house is brand new and designed to the highest spec in every detail. Listed for $104 million (£79m) in 2021, it’s got 10 bedrooms and some jaw-dropping amenities you won’t find in many London homes…

Stepping inside the grand front doors, the double-height hallway leads through to a striking formal drawing room, which features a statement black marble fireplace, a coffered ceiling and tiled floors. Expertly paired with modern furnishings, it makes for an unusual space; miles away from the predominantly neutral 'McMansions' you so often find. Elsewhere on the ground floor there's a dining room, family kitchen, office and guest cloakrooms. 

Spread over three floors, the home has a number of opulent bedrooms. The master suite sits on the first floor, alongside two guest bedrooms and boasts a walk-in wardrobe as well as two separate marble bathrooms. Now that's what we call luxury!

The lower ground floor is jam-packed with the most luxurious amenities. A 45-foot swimming pool sits alongside an in-house spa with a hot tub, sauna and hammam, with a dressing room that leads out to the private sunken courtyard. This floor also benefits from a games room complete with a cinema, bar, two wine cellars and a state-of-the-art biometric security room. 

Listed at $100m (£76m) back in 2019, Case House 5 features 12,000 square feet of floor space spread over one massive storey. The mid-century-style home is one of five built in this part of Malibu Bluffs and offers views of nearby Surfrider Beach, the Malibu Pier and Catalina Island. 

The modern home features contemporary interiors with spacious rooms that feature windows running the full length of the property. The six-bed, eight-bath home also has a separate guest house and an open-air courtyard for privacy. 

The brand new property has a largely open-plan layout. The kitchen incorporates a long island that extends into a breakfast bar with incredible views. Imagine drinking your coffee here!

The master bedroom is just as luxurious as the rest of the property with huge floor-to-ceiling doors that lead outside to the expansive decked area and the infinity swimming pool, of course with panoramic views. The house also includes maids' quarters and a basement. 

Fancy having the King as a neighbour? This Grade II-listed home in London, UK, sits just opposite Buckingham Palace. Once on the market for a reported $101 million (£76.5m), the home was also offered through a 'try before you buy scheme' and was up for rent at $62,500 (£47k) a week for interested buyers. 

Inside, the home has five reception rooms, which all come with soaring 14-foot ceilings, coving and floor-to-ceiling windows. Designed by Sir James Pennethorne, who was also the architect for Buckingham Palace's ballroom, the building was built between 1859 and 1861. Gone are the swags and traditional décor, in its place, is a clean, modern scheme finished to an impeccably high standard.

The spacious house has six bedrooms and six bathrooms and is arranged over seven floors with nearly 16,000 square feet of interior space. It offers five reception rooms and also comes with accommodation for staff.

The house was recently given a modern revamp to add lots of desirable features. The property includes a six-person lift, a state-of-the-art security system and an impressive spa area with a 32-foot swimming pool, sauna, gym and treatment room.

Once on the market for $150 million (£113m), this home was eventually sold to Tom Gores, the owner of the basketball team, the Detroit Pistons, in 2016 in a complex $100 million (£76m) deal in which multiple properties changed hands. As part of the unusual sale, Gores traded a number of his own Los Angeles properties. 

The mansion, which sits on two acres of land, was built in 2016 and offers 30,000 square feet of interior living space. With 10 bedrooms and 20 bathrooms that are spread across the main home, plus several guest houses, the modern property features a marble column and skylights in its double-height hallway.

The interior also features an expansive living space, a mirrored dining room, a wine room and a theatre complex with a separate entrance for guests. Elsewhere, a spa boasts a cascading water wall that flows into the lap pool, with a beauty salon just next door.

The 5,300-square-foot master bedroom leads outside to a private heated patio, while the main area is dotted with illuminated trees, three swimming pools and space to park more than 50 cars—one of the most jaw-dropping home features money can buy. 

This elegant equestrian property is currently on the market for $100 million (£76m). Set among the rolling hills of the Westchester countryside, just an hour outside of New York City, it's perfect for a deep-pocketed nature lover. Situated on 740 acres of land, it's also the largest privately-owned property in Westchester County. 

In the heart of the grounds perched at the top of a hill sits the main manor house. Accessed by a long, winding driveway, the four-storey residence has an opulent interior that's sure to entice any billionaire. Encompassing an enormous 24,000 square feet of space, the grand hallway leads through to the formal living room and dining area, which connects to the vast kitchen with a butler's pantry.

There are eight spacious bedrooms and eight bathrooms, but the pièce de résistance is the master suite. Situated on the third floor, it's the ideal plush private sanctuary, featuring a Japanese-inspired secret indoor garden and a luxurious limestone bathroom.

In the formal grounds, a pergola walkway leads to the impressive pool pavilion. At 4,000 square feet, it houses a 60-foot-long swimming pool and spa, flanked by rows of French doors that open out onto the idyllic gardens and paddocks. In addition to the gym, sauna and changing rooms, the pool house also includes an inviting lounge complete with a stone fireplace, as well as a kitchen.

In October 2019, two penthouses in the exclusive One Sydney Harbour project reportedly sold for a record-breaking AUS $140 million. That's around USD $105 million (£80m). The most expensive home ever sold in Australia, the mystery buyer purchased the top three floors of the building in Barangaroo South, Sydney.

Set to be completed in 2023, the finished home will be more than 17,000 square feet in size, with the new owner using the top two floors as a private residence, while the lower floor will be a separate guest space. 

With nine bedrooms, the luxury abode comes with soaring 26-foot ceilings and unmatched views over Sydney Harbour. This render shows a grand dining space featuring stone floors and huge windows that flood the opulent space with light.

The penthouse also boasts access to a private roof-top pool, spa and gym, as well as a master bedroom that is said to be bigger than most homes in the city.

It takes a lot for a property to stand out among the numerous architectural masterpieces on Bel Air Road, but this 12-bedroom party palace is the absolute pinnacle of suave living. Currently listed for $139 million (£105m) with Beverly Hills Estates, LA FIN has been five years in the making and offers breathtaking views of its stunning surroundings.

A spacious entertaining room with 23-foot ceilings greets visitors as they cross the property’s threshold, and LA FIN is a melting pot of high-end, European artwork in its interiors. A stunning marble fireplace from Portugal is framed by Italian, hand-crafted floor-to-ceiling oak cladding. Hand-crafted furniture imported from Milan is peppered throughout the rooms.

Each of the property’s 18 bathrooms is exquisite in its own way, with the primary washroom featuring 24 slabs of book-matched Calacatta gold marble, a 100 square-foot shower, a floating vanity and vast walk-in closets. Each of these components orbits around a deluxe bathtub cut from a single marble stone.

As for entertaining, LA FIN competes with the best villas in the business. Outside, there is a fully mechanised, 23-foot LED screen and multiple bars, while guests choosing to spend their time inside can visit the sub-zero vodka tasting room, private wine room or the elegant home theatre with motorised seating. Those keen on dancing the night away will enjoy the 6,000-square-foot nightclub.

This Park Avenue Penthouse sits on floor 96 of 96, and is the crowning jewel of this ultra-luxury tower. It had never been on the market before, according to Christie’s International Real Estate, it was last listed for sale in 2021 for $169 million (£128m) but was taken off the market in 2022. It's now back on sale by the owner for a whopping $180 million.

This penthouse is much bigger than your average inner-city flat at 8,255 square feet, and it includes a 93-foot living and dining room, so there is plenty of space for hosting guests. Panoramic views of Manhattan can be viewed through 240 linear feet of glass and the ceilings stretch to 12.5 feet.

The immaculate dining area looks out onto Central Park and shiny marble makes up the floors, countertops and splashbacks. The cabinets are a white lacquer and natural oak, complementing the luxury polished chrome Dornbracht fixtures.

The primary suite comes with a walk-through dressing room leading to two luxury bathrooms, where floating tubs and carved oval sinks sit atop heated floors. The other five bedrooms all come with ensuite bathrooms and ample closet space.

 

This breath-taking waterfront mega mansion in Greenwich, Connecticut was once the most expensive home sold in the USA, and now it could be yours for a clean $150 million, a jaw-dropping $30 million increase from its last listing price in 2014, The New York Post has reported. Copper Beach Farm, as the property is known, spans 50 lush rolling acres, including a solid mile of waterfront along the Long Island Sound.

While the house won’t be breaking any records these days if it sells for its current list price, the price tag still makes the property one of the most expensive homes on the market. The French Renaissance-style estate, once known as Kincraig, dates back to the 1890s and boasts four storeys, eight bedrooms, nine fireplaces, and a whopping 13,500 square feet of living space.

The home’s glamorous interiors, which the listing describes as ‘museum quality,’ are the height of old New England elegance, with 12-foot-high ceilings, gorgeous original oak panelling, plaster friezes and stately fireplaces. Meanwhile, its architectural style blends French Renaissance stone turrets with Victorian-influenced elements, such as the solarium, and nearly all of the rooms boast unobstructed views of the Long Island Sound.

Plus, if the main home’s interior and exterior grandeur aren’t enough to impress, the spectacular parcel also includes a three-bedroom gatehouse, a two-bedroom carriage house, two private beaches, a private island, a tennis court, a greenhouse, walled gardens, an apple orchard and a 75-foot-long heated pool and spa.

This four-tiered glass and concrete modern marvel appears to perch effortlessly atop this Californian clifftop, overlooking the glittering lights of downtown LA, with spectacular 370-degree views. With nine bedrooms and 14 bathrooms, the home boasts a whopping 20,841 square feet of living space, including a detached one-bedroom guest house complete with its own private pool and three different staff quarters with their own kitchen and laundry facilities.

The extravagant home is currently listed with Christie's International Real Estate for $150 million (£122.9m). Expertly engineered to maximise the benefits of indoor/outdoor California living, the home boasts numerous floor-to-ceiling sliding glass panel doors leading out onto patios, an infinity pool, a sunken outdoor firepit, an outdoor kitchen, lush lawns and multiple secluded cabana areas. Other luxurious bonus features include a state-of-the-art home gym and a massage room for afterwards.

The new construction offers an open floorplan, with numerous entertaining spaces flowing seamlessly into each other and out onto the surrounding terraces and patios. Lavishly appointed with high-quality materials, the entire main floor is a showpiece designed for hosting extravagant parties. A particular highlight is the chef’s kitchen, which features Miele and Gaggenau appliances, top-quality finishes and honed quartzite countertops.

 

The home’s luxurious master boasts an entire wall of glass overlooking downtown LA, and opening out onto an ample private terrace. The bedroom also offers indoor and outdoor seating areas, spacious his and hers closets, an adjoining dressing room and an ensuite complete with a soaking tub.
