Host Kevin O'Connor shows landscape contractor Roger Cook some local color on Austin's Town Lake, while back at the project house, green builder Bill Moore demonstrates how he's using a French drain and moisture barrier to try and lower the water table around the house to partially stabilize the foundation of the house. Inside, Kevin finds that the reclaimed flooring has arrived from Virginia, the new French doors are installed, and the kitchen cabinets, made from sustainable MDF and Lyptus, are going in. On a trip to the Lady Bird Johnson Wildflower Center, Roger and homeowner Michael Klug find creative ways to use native plants in residential landscaping. A new composite decking, made from 100% recycled wood and plastics, goes down on the deck off the master bedroom, while sustainable lighting designer Mark Loeffler shows Kevin how he'll use compact fluorescent and LED lighting to increase the energy efficiency of the house. In the upstairs bath, master carpenter Norm Abram finds tile contractors Robbie and Bryan Hawkins applying a "mud set" to the shower wall that will be tiled with 50% recycled-content subway tile.
