Insurance and real estate magnate Eli Broad put his retreat in Malibu up for sale on the open market this winter. The billionaire is asking $75 million for the beachfront modern, which sits on a half-acre of some of the most valuable real estate in the world.

The property—which includes a main house as well as a guest house—was custom designed for Broad by architect Richard Meier, and constructed in 2002. From the street, the house is hyper-modern; entirely white, with a unique sectional design that connects the two structures, and is formally reinforced by its segmented cosmetic flourishes.

On the ocean side, its plentiful glass gives the interior living style an intense feeling of nearly limitless continuation. It also sneaks a little Streamline into the architectural mix, evoking a classic ocean liner sensibility with its dramatically sculpted exterior and balustrades.

The 5,374 square-footer contains five bedrooms and seven baths. It is warm and uncluttered inside, with natural-toned hardwood floors, and smooth, plane-like walls that are occasionally sculptural. The act of entering the home and stepping into the great room is an act of liberation, as the hallway transitions into a soaring space with a massive, floor-to-ceiling bank of glass bringing the metaphor of the ocean and endless horizon inside. The master suite is similarly affecting, with a private balcony that overlooks the expansive deck on the main floor.

The guest house is open, and overlooks the lawn. It has a private patio, and upper-level deck.

Broad co-founded his first company—Kaufman and Broad—in 1957. His net worth is nearly $7 billion.
