Filled with imaginative storage solutions, improvisational uses of color, and undeniably cool details, many of our favorite outside-the-box spaces belong to kids. We've rounded up our favorite young guns in the décor department to convince you that keeping it young is the way to go. These adventurous, soulful rooms boast some serious style. From putting a cheeky spin on important vintage to letting a trapeze bar take center stage, we're totally smitten with their joyous energy and boundless creativity. Meet to the rooms that makes us never want to grow up.
