Structural and pest roblems at the project house, anatomy of the new landscape walls, challenges in hiding the necessary ductwork, and a visit to a utopian neighborhood of modern houses.

Master carpenter Norm Abram shows host Kevin O'Connor the newly discovered problems at the project house, most of them caused by the poor workmanship of a previous contractor. In the living room, one structural fix is already underway as general contractor Tom Silva prepares to install a flush frame beam made from LVLs that will carry the load of the second floor. Pest management expert Dan Fleicher shows Kevin the extent of the termite and carpenter ant damage, and suggests possible treatment options. Landscape contractor Roger Cook reveals the anatomy of new landscape walls; they'll be natural stone veneer over reinforced concrete. Kevin visits Six Moon Hill, a utopian neighborhood of modern houses created by the Architects Collaborative in 1948. Plumbing and heating expert Richard Trethewey shows Kevin one of the challenges he's facing in this minimalist modern house - no place to hide necessary ductwork.
