The world of luxury real estate is constantly evolving, and according to Forbes, there are more than 3,000 billionaires globally as of 2026. These high-net-worth individuals are not merely interested in extravagant yachts or luxury automobiles; they are also keen on acquiring homes in exclusive neighborhoods, often referred to as “billionaires’ rows.”

The Allure of Billionaires’ Rows

Properties on these illustrious streets often come with eye-popping price tags, typically in the double-digit millions. However, they represent more than just lavish living quarters. “Real estate in these elite areas isn’t solely about luxury; it’s increasingly viewed as a secure investment to preserve and grow wealth,” say Danny and Katie Bloomfield, directors at DKB Homes. These properties provide a means for billionaires to safeguard their capital, functioning similarly to fine art or other collectible assets.

The allure of limited availability amplifies the value of these high-end properties. As the Bloomfields note, buyers are not just purchasing a large residence; they invest in a prestigious location that embodies social status. To gain insights into where the world’s billionaires prefer to reside, we consulted several leading experts in luxury real estate.

Bishop’s Avenue in London

Bishop’s Avenue, often dubbed the world’s first “millionaires’ row,” epitomizes luxury living in north-west London. Its appeal began in the 1930s, as affluent residents were attracted to its serene outlook and stunning architecture. Following World War II, the construction of sprawling mansions drew an even wealthier demographic. Charles Leigh, director at Bishop’s Avenue Gardens, points out that notable figures such as the late King of Greece and the Sultan of Brunei contributed to this shift in prestige from millionaires to billionaires.

The address offers more than just exquisite homes. It boasts proximity to Hampstead Heath, featuring 800 acres of lush green space, as well as renowned educational institutions like University College School. The surrounding high streets are laden with artisanal shops, boutiques, and gourmet restaurants, solidifying Bishop’s Avenue’s status as a desirable location.

Dubai’s Selective Luxury

Dubai is another prominent hub for billionaires, showcasing not one but two exclusive “billionaires’ rows.” The Palm Jumeirah offers a blend of beachfront lifestyles, privacy, and top-tier amenities. “This area provides an unmatched combination of exquisite residences and world-class hospitality options,” states Jackie Johns, managing partner at Christie’s International Real Estate Dubai. A limited supply of waterfront villas elevates their allure and helps maintain high market prices, with homes starting at AED 2.6 million and soaring up to AED 340 million for ultra-luxury offerings.

Yet, the epicenter of ultra-high-net-worth concentration has recently shifted to Jumeirah Bay Island. Often referred to as “Billionaires’ Island,” this exclusive oasis boasts low-density development and maximum privacy through its 300-meter private bridge. Regan David Faulkner from Dubai Sotheby’s International Realty describes the island as “the highest density of billionaires per square meter,” reinforcing its status as a unique enclave.

New York’s 57th Street

One cannot overlook New York’s famed 57th Street, which also has a storied connection to billionaires. Known for its iconic skyline and luxury living, this corridor offers more than residences; it combines art, culture, fine dining, and elite shopping—all within a leisurely stroll. “It functions as its own ecosystem,” affirm Howard Morrel and Leslie Hirsch from Christie’s International Real Estate. The combination of cultural offerings and unparalleled access to Central Park reinforces 57th Street’s reputation as one of the globe’s most coveted addresses.

Given its sustained desirability, properties on 57th Street remain resilient despite economic fluctuations, making it a safe investment for international buyers seeking stability. As buyers become more deliberate in their choices, an emphasis on timeless architecture and wellness amenities has emerged, shaping the future of luxury living in these esteemed neighborhoods.
