“My work requires me to put on many different hats and costumes. I love slipping into these various characters, so I wanted my home to reflect lots of different themes and moods,” says the unapologetic voluptuary.

Architect Nicolò Bini of Line Architecture, Delevingne’s accomplice/enabler in decorative extravagance, fulfilled his client’s mandate with gusto. First there’s the nature theme, explicated in countless design gestures: walls sheathed in a Gucci wallpaper of overscaled herons; a massive snake carpet in the billiards room and a climbing-leopard carpet on the stair to the upper-floor fun house; a flock of bird sculptures by Mexican artist Sergio Bustamante; and a king’s ransom in ferns, palms, topiaries, and other houseplants.

Then there’s the fun-and-games theme, represented by a tented poker room; a jolly ball pit; a display wall of kooky hats and a costume room for dress-up parties; and two trampolines set into the ground near the floaty-stocked pool. “I love games—charades, beer pong, poker, Cards Against Humanity, tug-of-war, whatever feels fun. When my friends come over, the house turns into an obstacle course. It’s like an indoor/outdoor playground by way of Alice in Wonderland,” Delevingne observes. “If I’m having a bad day, I just hop in the ball pit. You can’t really cry in a ball pit,” she adds.

The white-brick residence, nominally English-country style, was built in 1941 for members of the Von der Ahe family, founders of the Vons supermarket chain. A deeply religious clan, the Von der Ahes are said to have hosted Pope John Paul II at the house when he visited L.A. in 1987. It’s unclear what His Holiness would have made of Delevingne’s vagina tunnel, a secret passageway concealed behind a low, painted panel, which leads from the living room to an adjacent bunk room. One enters the so-called rebirth canal through a vulval soft sculpture (think Judy Chicago on acid) and then proceeds to crawl out of a round washing-machine door suggestive of a rectum.

The pontiff also might have done a double take, if not a full-on spit take, at the sight of Delevingne’s attic party bunker, replete with a mirrored ceiling, a tasseled swing, serpentine soft seating inspired by the Courrèges logo, wrist and ankle restraints, and, of course, the obligatory stripper pole. “Cara is a creature of pure delight. This place is her ultimate expression of home—a Cara-style fantasy filled with references to the many things that turn her on,” Bini explains, emphasizing the joy he found in indulging the madcap desires of his free-spirited client and her circle of international glamour-pusses.

Yet despite all the blingy accoutrements—the Chanel surfboard, the David Bowie memorial bathroom, the Chemical X bull’s-eye sculpture made of thousands of Ecstasy pills suspended in acrylic—Delevingne insists that her house is more than simply a louche theme park. “It still feels like a home. There’s a proper dining room and living room and a great kitchen. But it’s also a kind of journey. The deeper in you go, the more treasures you discover,” she says.
