Every child deserves to have a space of their own in a house. Even when siblings have to share a room, it is important that the kids have at least some control over the look and feel of the space. The rooms featured in this post take from the idea of child-like whimsy and playfulness, then add a hefty dose of sophisticated style. The end results are rooms that, of course, beautiful, but also fun, colorful, and even practical. These rooms are more than a place for a child to lay her head, they are a slice of style that can grow with their occupants.
