When the new season begins, these special guests will contribute far more than special appearances - they'll be part of the design team. In each episode, the iconic "EM:HE" bus will pick up a new volunteer to join the team and help during the build, providing a rare chance to visit America's heartland and connect with real people who need help. Celebrity volunteers will pull up their sleeves, create a design project and put their personal stamp on the home. They will get to know the family's circumstances and needs one on one. In between pouring foundations and framing walls, some of the celebrity volunteers will jump right into the center of the town -- connecting with the locals, hanging out with the design team, spearheading a community project and bringing their unique personality and talents to the project. It's not all hard labor and sweat -- every episode has plenty of room for good times with good people. Getting on the bus will allow America to get to know the celebrity volunteers in an entirely new way -- as a real person who wants to make a real difference.
