As work winds down and winter winds up, Kevin and Roger assess the exterior transformation. Erik Kaminski and Kevin build a custom closet from off-the-shelf piping. Norm and Tommy walk through the mudroom and living room to see Kristina 's designs. Richard shows Kevin the brand-new geothermal heating and cooling system. April and Kristina give Kevin a tour of the second floor. Downstairs, Norm and Tommy chat with Erik and Mike Connor about the building process. The entire team meets in the kitchen to celebrate another job well done.
