On the North Shore of Massachusetts, homeowners Bill and April Harb begin building their dream home on a plot of raw land. The traditional farmhouse will look like it's been there for 200 years, but the building methods are at the forefront of innovation. Bill shows Kevin and Roger the site plan and walks them around the property, pointing out the first steps in the process. Norm and Tommy tour other factory homes built 5 years ago and 105 years ago, learning about the methods used for assembly. Back at the site, Kevin meets general contractor Erik Kaminski, who is leading the tree-removal process. Richard meets town official Brendhan Zubricki, who's performing a perc test to assess the soil.
