Remember when your home was decorated with mom and dad's hand-me-downs? That's what two hip Trading Spaces designers faced when they arrived in Washington, D.C., for this episode.

Designers Dez Ryan and Douglas Wilson assist two lovebirds as they trade spaces to make their digs more millennium friendly. Carpenter Ty Pennington assists.
