“Khloé’s house was a giant play palace built for a boisterous young man. We decided to give it some romance, bringing it back to its Mediterranean roots.”

For Kourtney, on the other hand, the focus was her three children: sons Mason and Reign, ages six and one, and three-year-old daughter Penelope. “We wanted to make it sophisticated but family-friendly,” notes the decorator. “She’s all about her kids.”

So there it is—one’s a little bit cozy, one’s a little bit rock-and-roll. Khloé, in characteristic fashion, puts a finer point on the distinction:

“Our tastes are very specific and completely different,” she says, laughing.

Bullard provided all the exotica Khloé coveted, dressing her home in a kaleidoscopic array of Moroccan, Turkish, and Middle Eastern flourishes. His coup de théâtre is the tented living room—an ethereal white fantasy presided over by a massive Levantine mirror with silent-film-era allure. That parlor opens onto a vine-covered terrace, where hanging daybeds sway gently in the Pacific breezes. As Bullard explains, “Khloé wasn’t interested in a traditional take on Moroccan style, so we cleaned up the lines and gave it a more vibrant, contemporary feel.”

When we go furniture shopping, I stand there tapping my foot while Kourtney shows me modern pieces. Then we head somewhere full of exotic, beautiful things and all she can say is, ‘I like nothing here.’

Yet for all the drama of these spaces, the room that perhaps best reflects Khloé’s vivacious spirit is her gargantuan closet—a treasure chest of ensembles meticulously organized by color and style—devised from two erstwhile bedrooms. “I don’t have kids, so why not?” says Khloé, who recently debuted her talk show, Kocktails with Khloé, on the FYI channel and is working on a new makeover reality series for E!, the same network that has made Keeping Up with the Kardashians a sensation. “I was very hands-on in the design process. I’m obsessed with details, so I can be a bit controlling, but it’s only because I’m genuinely curious.”
