In life, you either have charm or you dont. But in a house, you can always add it. That was the task at hand for Ariel Okin with this young familys home. Even though it wasnt old by architectural standards, it had been a little unloved, she says of the center hall colonial, built in the early aughts in Oyster Bay, New York. The mandate was to channel the homeowners free-spirited sensibilities while maintaining the houses traditional bones. Its classic prep meets traveling bohemian, Okin says.Related StoriesThe house didnt need a complete overhaul, but we definitely did a cosmetic gut, she says. The designer brought in warm yet slightly unexpected hues: coral, plum, and marigold, often in varying tones, to create tension. She wasnt afraid of pattern, which was amazing and so fun, says Okin of her client. It also helped to layer in some unpredictable touches: A sitting room got a ceiling more lustrous than a mollusk shell, and an existing built-in bar was painted a lush purple. The glossy aubergine bar definitely tied into my clients love of jewel tones, says Okin. The finishes throughout are hard-wearing for a growing family with a rescue dog. (For example: The polypropylene rug in the breakfast nook looks like sisal but can be cleaned like vinyl.)Its classic prep meets traveling bohemian.Okin balanced the bolder choices with design elements worthy of The Official Preppy Handbook, layering in stripes, woven natural fibers, scallops, and plates as wall artdecidedly orthodox touches beloved by generations. In the family room, the stripes on the rug really anchor that space because it is so vast, Okin says. The final result is exactly what the homeowner originally conjured. Its a traditional home, but it also has a curated assortment of things from all over the globe, Okin says. Its warm and collected and lived in.
