No more dated decor for two teenage boys who had outgrown the “Jack and Jack” bathroom they shared between their bedrooms. “The space was not age appropriate and my goal was to design a space that would appeal to them both now and in the future,” Mimi said. “I wanted to give it a traditional feel, but with a modern edge to it.” The extra touch? The teens were body builders and very conscious of tracking their progress: note the ingenious niche for a scale hidden beneath the folded towels.
