Karlie Kloss and Josh Kushner just dropped $29.5 million on Malibu's legendary Wave House. Take a look inside.

Before crooner Rod Stewart scooped it up in the 1970s, or record executive Mo Ostin bought it from him in 1980s, the so-called Wave House of Malibu was owned by Glenn and Gerry Cooper.

The Coopers were friends with Gesner, a California architect, and commissioned him to design a house for their family that epitomized their love of the outdoors. 

After the group found the site — a hidden cove with good surf up the coast from the famous Malibu Colony neighborhood — Gesner spent two days on a surfboard bobbing out at sea, peering back at the parcel.

It was on a 12-foot balsa wood surfboard that the architect first sketched the house with a grease pencil, the lore goes.

"It was exactly as it is now, in every way, thrusting out into the surf at high tide and nestled back in the sand at low tide," he told Lisa Germany in her 2012 book "Houses of the Sundown Sea: The Architectural Vision of Harry Gesner."

"It was as if we lived within, not apart from the forces of nature, and surged with her changing moods," Glenn told Germany.

"Such immediate challenges of nature caused all of us to be always responsive, alive, and aware. Such constant change of the tides reminded us of the fragility of life, of the moods and forces of nature," she added. "And the powers of nature drove us all to go farther, to be better, to meet the challenges of each day with undaunted bravado."

For its quirky exterior that mirrors the swells of the Pacific Ocean it faces, Wave House has become an icon of California midcentury architecture since its completion in 1963. 

According to the listing, the primary suite is also located close to the beachfront deck.

Five other bedrooms, most of which have their own views of the ocean, are located on an upper level of the property. 

A smaller structure that doubles as a guesthouse and garage also houses other bedrooms. 

The original material remains under the stucco that was added on in later years.

"Oftentimes, you can have too much view and you need a foreground to look around or an inner view to rest your eyes and thoughts on," Gesner said of the fireplace.

Another focal point in the room is its sunken conversation pit, a favorite midcentury design convention.

"For me, as a mother, I experienced the inner space as an overreaching large bird with its body and two wings covering and protecting me and my brood, especially significant when the vagaries of tidal forces and storms brought the ocean surging under the deck," Glenn told Germany.

To that, Harry replied, "I wish people would not insist that something looks like something else, but they do. It's human nature and a bore."

The Journal reported that Ostin, who died in 2022 at age 95, oversaw Frank Sinatra's Reprise label and signed acts like Jimi Hendrix, Prince, and Madonna.

He bought the Wave House from the original owners in 1987.

Gesner, the architect, died in 2022 at the age of 97.

After designing Wave House, Harry bought land next door and built himself and his family a home inspired by sandcastles. 

Completed in 1974, the aptly named Sandcastle house hit the market in May 2023 for $27 million. The six-bedroom, six-bathroom property sold in February 2024 for $13.5 million. 

Zen Gesner told the outlet he feels confident buyers would not want to tear down the homes.

"It's our hope that nobody ever has that intention," he said.
