UK Sotheby’s International Realty, a name synonymous with luxury property, has recently unveiled its latest endeavor tailored exclusively for the world’s wealthiest individuals. The new service, named The Family Office, is designed to cater specifically to global ultra-high-net-worth (UHNW) individuals and multi-family offices, offering them unparalleled access to some of the most desirable properties on the planet.
The Family Office aims to be a one-stop-shop for the affluent, providing not only investment advice but also a suite of related services that include financial management and staffing solutions, all reinforced by expert legal guidance. Spearheaded by Marcus O’Brien, this initiative promises a seamless experience for clients seeking to buy or sell top-tier real estate assets. O’Brien, a prominent figure in luxury real estate, is part of The Market Leaders Group—a select circle within Sotheby’s International Realty, composed of 50 agents renowned for their market-leading transactions across a network of over 26,500 colleagues.
Global Network and Exclusive Access
The Family Office distinguishes itself through its exclusive network, The Market Leaders Group, which handles over $8.2 billion in annual transactions for its clients. This network provides a unique platform for showcasing luxury properties and fulfilling the sophisticated acquisition needs of its clients. Additionally, the office maintains a strategic relationship with both Dubai Sotheby’s International Realty and Saudi Arabia Sotheby’s International Realty, enhancing its capability to serve prominent family offices in the Gulf Cooperation Council (GCC) region with their real estate portfolios and investment strategies.
A Look at the Global Wealth Landscape
Highlighting the breadth of its target market, The Family Office points out that there are over 28,420 centi-millionaires and around 2,350 billionaires globally, predominantly concentrated in 10 countries. These countries include the United States, China, Hong Kong (SAR China), Singapore, the UK, France, Japan, Switzerland, India, and the United Arab Emirates. Furthermore, the primary residences of these ultra-wealthy individuals are largely clustered in 16 key cities known for their opulence and economic clout—New York, San Francisco, Los Angeles, London, Beijing, Shanghai, Singapore, Hong Kong, Chicago, Paris, Tokyo, Geneva, Houston, Zurich, Mumbai, and Dubai.
Commitment to Enduring Value
George Azar, chairman and chief executive of UK, Dubai, and Saudi Arabia Sotheby’s International Realty, emphasised that The Family Office is focused on creating lasting value for its clients. According to Azar, the service will facilitate the acquisition and management of the world’s most coveted real estate and luxury assets, which are often not available on the open market.
