Work on the Dutch Colonial Revival continues as master carpenter Norm Abram recaps the progress on the addition, then turns his attention to the kitchen where general contractor Tom Silva and host Kevin O'Connor are working to reframe the existing walls to accommodate new door and window openings. Upstairs, Tom installs a large new window in the library that is really six individual window units grouped together, while downstairs, kitchen designer Tamara Raymond helps homeowner Gillian Pierce envision her new kitchen with the help of paper mock-ups. Kevin pays a visit to former This Old House architect Treff LaFleche to see how he renovated his 1906 Gambrel-style Victorian to achieve superior energy efficiency and a LEED green building certification. In the second half of the Hour, on Ask This Old House, landscape contractor Roger Cook joins plant expert Carrie Kelly at a nursery to learn about container gardening. Then, up in the loft, Tom and Kevin discuss different types of flooring, including solid wood, engineered wood, ceramic tile, vinyl, and linoleum. Next, Roger, Kevin and Tom, along with plumbing and heating expert Richard Trethewey ask, "What is it?" Afterward, Kevin and a television antenna expert help a homeowner install a new rooftop antenna for his digital TV.
