Where the Living is Easy

With Christian's—and Felicitas's help—Katleen has created a symphony of texture, finish, tone, a getaway for her family in the otherwise hectic Hamptons. Here, having fun doesn't mean attending an evening fund-raiser, but watching the kids gallop across the yard on a horse-shaped tire swing or cooling off beneath the outdoor shower. "I'm a very calm person, and this place just oozes calmness," Katleen says. "That's a real reflection of who I am—we really feel at home here."
