These two are pros of new ventures. Bill, an entrepreneur and real estate developer, is also an author and recently a Food Network host. In addition to her work on E!, Giuliana designs a clothing line for HSN, has introduced her own wine collection, and has written three books, including a new memoir, Going Off Script. Did we mention they also own Chicago restaurants RPM Italian and RPM Steak? Doing it all in their work lives meant they could use a hand when it came to reinventing their new house. Giuliana knew exactly who she wanted for the role: Lonni Paul, the designer behind the welcoming interiors of their home in the Brentwood neighborhood of Los Angeles. Paul’s first challenge was to address the brownstone’s narrow, vertically driven architecture and delineate space so excessive trips up and down the stairs were eliminated. Paul’s solution was to reinterpret the couple’s beloved blue color scheme to suit the sometimes-cloudy Chicago weather, so unlike the L.A. sunshine that the Rancics were accustomed to. “I used blue in California to tribute the water,” Paul says. “But in this rowhouse, which doesn’t allow light to pour in from either side, the blue functioned as a tool to create light and airiness that wouldn’t read heavy and dull when the sky turned cold and gray.” Pale blue infuses the living room, decorated in traditional fabrics that include floral linen for the window panels, windowpane-plaid on a pair of wing chairs, and wide blue-and-gray stripes covering an ottoman. The soft color scheme, which also includes plenty of mood-lifting white, allows a bold, graphic Tony Tasset painting hung above the fireplace to command attention. Artwork by Hunt Slonem features bunnies that are painted on a base of indigo-colored diamond dust. The piece adds shimmer to the room and nods to the grand sparkle of a floating chandelier from Windfall Contemporary Crystal Lighting. “When I began collecting, it was suggested to me that I start with artists from my generation,” the 41-year-old says. “In my youth, the limousine represented wealth and status. It was chic to pull up in a stretch limo. Now, the limousine is somewhat archaic, and high-profile event transportation happens in a black SUV.” A Lee Industries tufted ottoman contrasts the geometric chevron of the rug. The floor lamp is by Ralph Lauren. "We debated between glass or mirror fronts on the cabinets," says Giuliana, who dresses to the hilt for her lavish E! assignments. “But I don’t keep pieces that I don’t wear. I edit my things often, and knew that the cabinets would be visually organized.” The two-story primary bath/closet features tile from Walker Zanger. Plumbing fixtures are by Hansgrohe. Wing chairs from Bernhardt are covered in blue linen. Custom wallpaper featuring vintage planes adorns the walls in Duke’s room. Books, toys, and artwork decorate the bookcase.
