Stylish Children's Playroom

Joy and Cole Portis and their three children live in a 15-year-old brick colonial home in Montgomery, Ala. Joy has decorated most of the house with sophisticated colors and styles. When it comes to designing a playroom for the children, she's drawing a blank. Joy and Cole would like to transform their upstairs den and enclosed porch into a functional, stylish children's den and play area that can also double as a guest room. Their budget for the project is $25,000.
