Once upon a time, the streets that we now refer to as ‘billionaires’ rows’ began as enclaves of architectural ambition – grand avenues offering unrivalled space, design and proximity to cultural or financial centres.
Over time, as wealth concentrated globally, these pockets became shorthand for exclusivity, attracting UHNW buyers seeking not only homes, but statements of identity.
Today, billionaires’ rows are defined less by geography and more by an unmistakable combination of scarcity, pedigree and global visibility – whether it’s The Bishops Avenue in London, the 16th arrondissement in Paris or the super-tall towers on Central Park South in New York City – each encompass prestige, security, space and privacy.
Yet their evolution has been shaped by the shifting priorities of UHNWIs. With rising concerns over surveillance and data breaches, privacy is becoming a luxury in itself. Demand is growing for homes with private entrances, underground parking and in-house security teams, while digital privacy services are gaining traction among family offices.
Increasingly, these streets must deliver not only prestige, but a lifestyle ecosystem tailored to a mobile, discerning global elite whose expectations continue to redefine the meaning of ultimate luxury.
London: The Bishops Avenue

The Bishops Avenue is a wide verdant street that has long been one of London’s most prestigious addresses.
From its 19th-century origins as part of the Bishop of London’s hunting park, to first being coined Millionaire’s Row’ in the 1930s, after the Second World War, the character of the road transformed, evolving into what became known as Billionaire’s Row – attracting ultra-high-net-worth individuals globally.
The international super rich, including the last king of Greece, Constantine II, the Sultan of Brunei and Lakshmi Mittal, helped elevate this status change. This reputation endures today, with detached houses on the avenue averaging £10.4m, reaching highs of £24.5 million – 1.7 times more valuable than properties in the surrounding area, according to Savills.
Property: Bishops Avenue Gardens
To meet the evolving needs of modern buyers, traditional single dwellings along The Bishops Avenue are being thoughtfully repurposed into multiunit new homes that offer world-class amenities, 24-hour security, and the convenience of having everything under one roof.
At the forefront of the street’s contemporary evolution, Bishops Avenue Gardens sets a new standard for living. Bishops Avenue Gardens is a landmark new development introducing 36 meticulously designed residences.
Set in 2.5 acres of Arts & Crafts-inspired grounds, the homes span lateral apartments, duplexes and penthouses that all celebrate the interplay between nature, craftsmanship and contemporary living. The development offers a new type of residence that appeals to a broad spectrum of discerning buyers.

Paris’ answer to a billionaires’ row is not a street at all, but a gated enclave in the 16th arrondissement, Villa Montmorency. Established in 1853 on former aristocratic lands, it comprises around 100 private homes across winding tree-lined lanes in Auteuil village.
Strict regulations prohibit rentals and subdivision, while minimum house and garden sizes preserve space and privacy.
In an era where UHNWI individuals value discretion, Villa Montmorency offers complete anonymity. Properties of approximately 400sq m requiring renovation have recently transacted between €7m-€9m, while exceptional 1,000sq m properties featuring indoor pools and expansive gardens can reach tens of millions of euros.

Singapore: Nassim Road
By Harmeet Bedi, Managing Director, Christie’s International Real Estate Singapore
Nassim Road is Singapore’s premier Good Class Bungalow (GCB) enclave.
With the nation capping GCB supply at around 2,000 nationwide, the road is one of the city’s most coveted addresses.
Long regarded as a symbol of wealth and status, the street attracts tycoons, international investors, and diplomats.
Large, regular plots with redevelopment potential, coupled with its prime District 10 location near Orchard Road and the Botanic Gardens, reinforce long-term capital preservation.
Nestled within the Tanglin/Orchard precinct, Nassim Road offers close proximity to elite schools, embassies, and exclusive clubs, while remaining a quiet, low-traffic street sought by those who value discretion, privacy, and security.
Property: Oxley Residence
While non-Singaporean citizens are generally not permitted to purchase GCBs on Nassim Road, luxury condominiums and boutique residences nearby remain highly attractive to international buyers.
An example of this is a strata-titled townhouse at Oxley Residence. Spanning 8,966 sq ft of mostly covered space over four levels, it is a rare freehold offering of a substantial size. Following a $3m interior design renovation, the home features five bedroom spaces – one of which has been converted into an entertainment area with walk-in wine cellar, stylish bar and pantry, and the other into a home theatre plus home office, five bathrooms, a designer kitchen, two dining room areas and plenty of common spaces.

Deep Water Bay has distinguished itself as the definitive billionaires' row for Hong Kong's most prominent business dynasties.
Its magnetic pull goes beyond the tranquil environment and stunning coastal scenery. Deep Water Bay offers an exclusive, self-contained lifestyle anchored by prestigious amenities such as the Hong Kong Country Club and the Hong Kong Golf Club.
Recently, mainland buyers demand total and unwavering confidentiality, willing to go to extraordinary lengths to conceal their identity and protect their family's seclusion.
In response to this discerning clientele, focus has shifted from the tangible to the experiential, with concierge services, wellness facilities, and lifestyle management reaching five-star hotel standards. This evolution is blurring the line between a private residence and a managed, exclusive club.

Swire Properties
During the recent sale of 6 Deep Water Bay Road by Swire Properties, our team participated in the bidding on behalf of a client and witnessed an exceptionally competitive process, with multiple high-net-worth parties vying for one or both of the houses on offer.
The intensity of the interest was a clear signal of the market's depth. Swire ultimately selected a buyer who acquired both houses in a single, record-setting transaction valued at HK$147,010 per sq ft.
It was only later that we discovered many of our own clients were among the under bidders, underscoring the immense, yet carefully guarded, demand for this new breed of ultra-exclusive, amenity-driven address on Deep Water Bay.
New York: 57th Street
By Howard Morrel and Leslie Hirsch, founders and leaders of the Christie’s International Real Estate Trusts & Estates Division
What distinguishes 57th Street is that it functions as its own ecosystem. It’s not just beautiful residences; it’s art, architecture, culture, hospitality, and flagship retail layered into a single corridor.
Buyers can step from a private residence into world-class galleries, concert halls, Michelin-level dining, and iconic retail within minutes.
Very few streets globally offer that density of cultural and lifestyle capital, and 57th street also pairs this with direct access to Central Park.
Over the past several years, sales above $20 million have continued to close consistently, even through shifting macroeconomic cycles. Trophy properties with exceptional views, layouts, and provenance continue to command global attention.
Property: 66B at 157 West 57th Street
The ultra-prime segment of 57th Street continues to operate in a market of its own. According to Christie’s International Real Estate’s January 2026 57th Street Market Report, the $5m+ market currently includes around 50 active listings, with six properties in contract and 43 sales recorded over the past 12 months. Average prices stand at roughly $5,340 per square foot, while the median price sits just above $5,170 per square foot.
The average luxury sale price across the corridor is approximately $25.6m, with a median of around $17.6m. Even at this level, negotiation remains part of the process, with buyers securing an average of 8.6% below asking price and properties spending around 114 days on the market.
A recent example is residence 66B at 157 West 57th Street, which sold for $24m — a reminder that trophy homes overlooking Central Park continue to attract sustained global demand.
