What Is the Most Expensive Neighborhood in the World?
Mareterra in Monaco is the most expensive neighborhood in the world as of 2026, with property prices of approximately EUR 51,967 per sqm in 2024 according to IMSEE (Monaco Real Estate Observatory). Built on 15 acres of reclaimed Mediterranean Sea, it is the newest and most extreme example of ultra-prime real estate on the planet. Before Mareterra opened, Avenue Princess Grace and Kensington Palace Gardens held that distinction, each commanding prices above $86,000 per square meter.
Summary Box: The world’s most expensive neighborhoods span from Miami’s Gables Estates ($17M average) to Monaco’s new Mareterra district ($9,300 per sq ft). Having visited and reported on luxury real estate markets across five continents during my 11+ years covering the global luxury sector, I’ve witnessed firsthand how these elite enclaves blend exclusivity, breathtaking locations, and extraordinary amenities.
This guide reveals 29 of the world’s priciest addresses where property values regularly exceed tens of millions of dollars, featuring insights from my travels to London’s Mayfair, Paris’s historic arrondissements, Monaco’s coastline, and California’s most exclusive coastal communities.
Luxury real estate has always captivated me since we started covering the luxury lifestyle sector over a decade ago. From immense mansions in historic city centers to pristine coastal enclaves, the most expensive neighborhoods in the world represent the pinnacle of prestige and wealth. During our travels reporting on luxury destinations, we’ve had the privilege of experiencing these elite locales firsthand – from walking the tree-lined streets of Kensington to exploring waterfront properties in Miami.
These neighborhoods attract billionaires, celebrities, and business tycoons seeking the ultimate in high-end living. Their sky-high property values reflect not just the quality of individual homes, but also the cachet of the addresses themselves. In our experience documenting luxury travel and lifestyle, these exclusive communities share common characteristics: unparalleled privacy, world-class amenities, and locations that money simply cannot replicate.

1. Mareterra, Monaco
In December 2024, I learned that Monaco christened what experts are now calling the most expensive neighborhood in the world – Mareterra. This brand-new district features approximately 100 condominiums priced at around $9,300 per square foot, and several villas reportedly sold for $200 million each.
What makes Mareterra extraordinary is that it was built on 15 acres of land literally added to Monaco by filling in part of the Mediterranean Sea. Given that Monaco is less than one square mile in total and has more billionaires per capita than any other country, this development represents the highest density of ultra-high-end real estate globally. According to the Knight Frank Wealth Report, over 30% of the population here are millionaires.
When I visited Monaco recently, I was struck by how this tiny principality continues to push boundaries in luxury real estate, creating entirely new land to meet demand from the world’s ultra-wealthy. Experience Monaco like a local with a private VIP walking tour of the casino, palace and many more attractions.
2. Gables Estates, Coral Gables (Miami), Florida
As of 2026, Gables Estates continues to rank as potentially the most expensive neighborhood in the United States, with average home values reaching approximately $17 million. During my visit to this pristine gated community in Coral Gables, I was impressed by the waterfront luxury on Biscayne Bay, which combines privacy with panoramic water views that few other American neighborhoods can match.
The exclusivity of Gables Estates is enhanced by its world-class amenities, including access to golf courses, tennis courts, and a private yacht club where membership application fees start at $100,000. Property values in Gables Estates have shown remarkable resilience and growth, attracting investors and buyers from around the world.
The neighborhood’s appeal stems from its magnificent waterfront properties and strategic location with easy access to Miami’s cultural attractions, international airport, and business centers.
3. Port Royal, Naples, Florida
With average home values exceeding $16.2 million and continuing to appreciate, Port Royal in Naples stands as the second most expensive neighborhood in the United States. During my reporting trip to this exclusive waterfront community on Florida’s Gulf Coast, I discovered sprawling estates, many exceeding 5,000 square feet, with direct beach access.
Named after an antique Jamaican port city in the late 1940s, Port Royal’s prestige was further enhanced with the founding of the Port Royal Club in 1959. This members-only establishment offers luxury dining, entertainment, and social opportunities. According to Naples Daily News, in 2025, a waterfront estate at 2170, 2200, and 2340 Gordon Drive sold for $225 million, making it the highest residential sale in the United States that year.
Port Royal’s limited housing inventory contributes to its consistently high property values, with most homes featuring ranch-style architecture, expansive lots, and private docks with deep-water access.
4. Mount Nicholson Road, The Peak, Hong Kong
Based on my research and conversations with luxury real estate experts in Hong Kong, Mount Nicholson Road on The Peak is considered the world’s second most expensive street. Between 2015 and 2019, this exclusive address saw 35 ultra-prime sales with an average of $81.8 million per sale.
The Peak offers unparalleled views of Hong Kong’s brilliant urban landscape. Lau Chauin, daughter of Heungkong Group chairman Lau Chi-Keung, paid over $80 million for what’s called Asia’s most expensive flat in the ultra-luxury Mount Nicholson project – an incredible $18,050 per square foot.
The Peak’s allure extends beyond stunning vistas. Residents enjoy a tranquil environment away from the bustling city center, while still having easy access to one of Asia’s most important financial hubs.
5. Kensington Palace Gardens, London
Having lived and worked in London and other European capitals, I can attest that Kensington stands as one of the most expensive neighborhoods in the world. At the heart of Kensington’s prestige lies Kensington Palace Gardens, often referred to as “Billionaires’ Row.”
This exclusive street houses some of the most valuable properties globally, with prices reaching hundreds of millions of pounds. Indian steel tycoon Lakshmi Mittal and other industrialists are among the famous residents. The average price per square meter in this area is about $107,000.
The neighborhood’s appeal extends beyond its high-end real estate. In my experience exploring the area, Kensington offers proximity to world-renowned museums, luxury shopping districts, and expansive green spaces like Hyde Park. The Japanese and Chinese embassies are also located here.

6. West 57th Street (Billionaires’ Row), New York City
Between 2015 and 2019, I tracked how West 57th Street, otherwise known as ‘Billionaires’ Row,’ recorded a staggering 41 ultra-prime sales – a sum of around $1.5 billion spent. This makes it one of the most concentrated areas of wealth in New York City.
Michael Dell, founder and CEO of Dell Technologies, paid a reported $100 million for a penthouse in Steinway Tower in 2014, the most expensive sale in the US at that time. What fascinates me about Steinway Tower is that it’s also the world’s skinniest skyscraper with just a single residence on each floor.
During my visits to New York, I noticed that this stretch offers unparalleled views of Central Park and represents the pinnacle of Manhattan luxury living.
7. Beverly Hills & Beverly Crest, Los Angeles
In our coverage of Los Angeles luxury real estate, Beverly Hills stands as one of the world’s most iconic and expensive neighborhoods. This legendary enclave has been synonymous with wealth and glamour since the early 20th century, attracting Hollywood royalty, international business moguls, and ultra-high-net-worth individuals.
The most exclusive properties are found in the hills above Beverly Hills, particularly in Beverly Crest, where ultra-contemporary estates regularly list for over $100 million. Some properties span 50,000 square feet across six-acre promontories with commanding views of the entire L.A. Basin.
One ultra-luxury Ed Tuttle-designed compound features 16 bedrooms and 27 bathrooms, along with amenities including a movie theater, bowling alley, wine cellar, infinity-edge pool, and lighted tennis court. These hilltop estates offer maximum privacy while maintaining proximity to Beverly Hills’ famous Rodeo Drive shopping district and the entertainment industry infrastructure.
The flats of Beverly Hills – particularly the area known as the “Platinum Triangle” bounded by Beverly Drive, Canon Drive, and Sunset Boulevard – command astronomical prices for their prime walkable location. Even modest-sized homes in this area regularly sell for $10-20 million simply based on their 90210 zip code cachet.

The 300-meter street may be one of the shortest in Singapore, but the presence of fancy apartments, such as The Marq (with interiors designed by Hermès), has certainly made this neighborhood exclusive. The Marq made headlines when a unit – the world’s first apartment fully decorated by Hermès – sold for $29.5 million.
Paterson Hill, referred to as Billionaire’s Row, is home to former Miss Singapore beauty queen Rachel Kum and Facebook co-founder Eduardo Saverin.
15. District 10 (Nassim Road), Singapore

Beyond Grosvenor Square, Mayfair as a whole stands as one of London’s most expensive neighborhoods. The roots of Mayfair date back to the 17th century, when 500 acres of rural land were purchased by an heiress.

From art galleries and architectural marvels to exquisite parks such as the Luxembourg Gardens, this neighborhood offers exceptional cultural richness. However, somewhat at odds with its bohemian reputation, the neighborhood’s housing costs are now the most expensive in Paris.

Top 10 Most Expensive Neighborhoods in America

Florida’s dominance reflects the state’s combination of waterfront scarcity, zero income tax, and sustained demand from domestic and international ultra-high-net-worth buyers.
What Makes a Neighborhood the Most Expensive in the World?
Across the 29 neighborhoods documented in this guide, a consistent set of factors pushes residential prices beyond $2,000 per square foot and into territory most buyers will never access.
●Absolute scarcity of land. Monaco covers less than one square mile. The Peak in Hong Kong has a finite number of hillside plots. Kensington Palace Gardens contains a single private road. When supply cannot grow, prices have only one direction to travel.
●Tax and legal environment. Monaco’s zero income tax for residents and Singapore’s stable legal framework actively attract ultra-high-net-worth individuals who can live anywhere. Geneva and Zurich benefit from Switzerland’s political neutrality and banking secrecy traditions.
●Trophy asset status. Properties at addresses like West 57th Street or Avenue Montaigne carry a signaling value beyond their physical attributes. Owning at these addresses communicates status in a way that a $50 million home in an anonymous suburb cannot.
●Proximity to financial and cultural power. Every neighborhood in this guide sits within reach of a major financial center, a world-class cultural institution, or a globally recognized leisure corridor. The most expensive addresses compress access to money, art, and influence into a single postcode.
●Security and privacy infrastructure. Gated access, 24-hour concierge, private security, and diplomatic-area policing are standard rather than exceptional at these price points. Buyers are not just purchasing square footage, they are purchasing an environment that protects their privacy and safety at scale.
Economic Factors Influencing Property Prices
In my years reporting on luxury real estate markets worldwide, I’ve observed several key economic factors that shape property prices in these exclusive neighborhoods.
Global Economic Trends
During periods of economic expansion, I’ve noticed that wealthy individuals and investors allocate more funds to luxury properties, driving up prices in exclusive neighborhoods. However, top-tier neighborhoods tend to be more resilient to market fluctuations than mid-market properties.
International trade patterns and globalization also influence property values. Cities with strong connections to global markets – which I’ve visited from New York to Hong Kong to London – often see increased demand for luxury real estate from foreign buyers and multinational corporations.
Currency Exchange Rates
In my experience tracking global luxury markets, fluctuations in currency exchange rates can significantly affect property prices in expensive neighborhoods. A strong local currency may deter foreign buyers, potentially cooling the market.
Conversely, a weaker currency can make properties more attractive to international investors. This effect is particularly pronounced in cities popular among global elites, such as London, Paris, and Monaco.
Political Stability
Through my reporting, I’ve learned that political stability is crucial in determining property values in high-end neighborhoods. Countries with stable governments and predictable policies tend to attract more long-term investment in real estate.
Cities known for their political stability – such as Geneva, Singapore, and Monaco that I’ve visited – often command premium prices in their most desirable neighborhoods. Strong legal systems protecting property rights, transparent tax policies, and favorable foreign investment regulations all contribute to sustained high property values.
Architectural and Design Standards
In documenting luxury properties across multiple continents, I’ve observed that the world’s most expensive neighborhoods showcase exquisite architectural features and cutting-edge design elements.
Luxury Building Materials
I’ve seen first hand how high-end neighborhoods utilize top-quality materials in their construction. Marble from Italian quarries often adorns kitchens and bathrooms. Exotic hardwoods like teak and mahogany feature in flooring and cabinetry.
Developers incorporate rare stones such as onyx and lapis lazuli for accent pieces. Custom-made fixtures crafted from precious metals add unique touches to interiors.
Sustainable Design Practices
During my visits to new luxury developments, I’ve noticed that eco-friendly features are increasingly important in upscale neighborhoods. Many properties boast LEED certification, showcasing their commitment to sustainability.
Solar panels, geothermal systems, advanced water recycling systems, and smart home technology optimize energy usage. Luxury and sustainability merge in these high-end areas, setting new standards for conscientious living.

What is the most expensive residential street in the world?
Mount Nicholson Road on The Peak in Hong Kong is widely considered the world’s most expensive residential street by average sale price, recording an average of $81.8 million per ultra-prime sale between 2015 and 2019.

Kensington Palace Gardens in London (often called Billionaires’ Row) and West 57th Street in New York City are close rivals.
Why is Monaco so expensive to live in?
Monaco is so expensive because it combines absolute land scarcity (less than one square mile of total territory) with zero income tax for residents, political stability, Mediterranean climate, and a concentration of billionaires that creates self-reinforcing demand. The principality has more billionaires per capita than any other country. When Monaco ran out of land to develop, it literally reclaimed sea bed to create Mareterra, now the world’s most expensive neighborhood at $9,300 per square foot.
Is Mayfair or Knightsbridge more expensive in London?
Kensington Palace Gardens, which sits at the Kensington and Mayfair boundary, is technically the most expensive address in London at approximately $107,000 per square meter. As broader districts, Mayfair (including Grosvenor Square at $45.5M average ultra-prime sale) tends to command slightly higher prices than Knightsbridge, though the most expensive single building in Knightsbridge (One Hyde Park, with a unit sold for £100 million) rivals anything in Mayfair. Both districts average prices well above $2,500 per square foot.
