The World’s Most Expensive Houses And Their Ultra-Rich Owners

The names and faces behind the world’s most iconic pieces of real estate.

By Nagidmy Marquez August 3, 2017

Have you ever wondered where the world’s most expensive houses are? Furthermore, who are the ultra-rich owners? For real estate enthusiasts and experts some of these houses are familiar. For the rest of the planet, a total mystery. provides the infographics of the world’s most expensive houses comparing the home values to Buckingham Palace. Not nearly as ornate as some other palaces in existence: the Saudi royals, for example, tend to style more opulently in comparison to their European neighbors. An important factor to remember: the property’s value in its entirety is not only the structure itself but who resides within it, meaning the Queen herself is more prized than the Palace, making it one of the most valuable structures on the globe.
