Master electrician Allen Gallant installs PVC conduit two feet below the surface of the driveway to allow the 200-amp service to reach the cottage. Using a ""mouse,"" a string, a pull rope, and a vacuum (known to the trade as a ""fishing system"") his crew hauls the heavy electrical lines underground from the street to the cottage, a span of more than 200 feet. Architect Sarah Susanka shows Kevin a 3,000-foot-square house that illustrates the fundamental design principles outlined in ""The Not So Big House,"" her best-selling book. On the second floor of the cottage, carpenter Jason Wood sisters new 2x8s to the existing 2x4 rafters and cuts a hole in the roof to accommodate the new dormer. Norm and Tom push the old roof section out and let the light in upstairs for the first time in almost 100 years.
