Landscape architect Gregory Lombardi shows host Kevin O'Connor the final design for the entry courtyards and water feature, as landscape contractor Roger Cook shows the formwork, rough plumbing and rough electrical on the structure. General contractor Tom Silva removes the old single-pane steel slider in the living room and replaces it with a more energy-efficient, insulating glass unit with a low-E coating. Master carpenter Norm Abram travels to Keene, New Hampshire, to meet artisan tile manufacturers Stephen and Kristin Powers for a tour of their showroom and factory. Custom pool specialist John Fitzgerald shows Roger and Kevin how his eight-member crew forms the bed of the water feature out of gunite.
