When Woodwyn Koons and Dmitri Siegel relocated from Philadelphia to Ojai, California, four years ago, they were excited to try on an entirely different design aesthetic, one more befitting their newly adopted state. “The 19th-century houses we lived in on the East Coast have so much ornament, and then you come to a place like California, where minimalism really makes sense,” Koons says. The kitchen of the midcentury ranch home they share with their two young children became the epicenter for their experiment in modernism. With the guidance of Los Angeles– based architect and designer Barbara Bestor, they set about transforming the kitchen into an open living area—a relaxed one-stop room in which to cook, eat, and gather. Four wall knockdowns later, their vision of a colorful, family-friendly home was achieved. “I do a lot of cooking, and I don’t feel isolated in the kitchen anymore,” says Siegel, a creative director. “It just seems like there’s now more of a connection with everybody.” Including their inner child: Instead of restricting bright hues to the kids’ rooms, Koons and Siegel worked them into the color scheme throughout the open living area. (“I don’t like the idea of fragmenting out design,” he says.) This democratic, nonrigid style extended to the materials they considered; they made thoughtful choices, opting for inexpensive and nontraditional where it made sense (a mirror backsplash behind the stove) and high-end and classic where it was called for (a marble backsplash everywhere else). The end result: a beautifully blended kitchen.
