Husband and wife Jay Z and Beyoncé recently purchased a beachfront mansion in Malibu for $200 million, and it currently stands as California’s most expensive home ever sold.

The property spans 30,000 square feet, and the structure itself is made of almost entirely concrete – one of the most expensive construction materials currently on the market. And guess what? This home was designed by an architect with no college degree and no formal education in architecture.

It was designed by the self-proclaimed “urban guerrilla” aka the samurai architect: Tadao Ando.
