Host Kevin O'Connor arrives to find homeowner George Mabry moving out and general contractor Tom Silva moving in. With a building permit in hand, Tom starts with the carport, dismantling it piece by piece on order to gain better access to the house. Kevin meets landscape architect Gregory Lombardi to evaluate the existing landscape, and finds that while much of the back yard is worth saving, the rest of the site will need to be completely reworked. Master carpenter Norm Abram meets project architect Will Ruhl at another modern house he recently designed on the island of Martha's Vineyard. Then, back in Cambridge, Will presents his design for George's house with the help of computer renderings and a 3-D model. The new house will still be Modern, but tempered by a warm palette of natural materials. The expansion allows for a combination library/dining room on the first floor (along with a powder room, mudroom, and wet bar), a new master suite upstairs, and a private guest suite housed in the new third-floor loft. Certified arborist Greg Carbone arrives to begin clearing the lot of the overgrown and dying trees
