The Billerica House - 12

We arrive at the house to find the last of the wallboard shipment being loaded into the basement. In the rest of the house, it's already hung and plastering has begun, homeowner Dick Silva gives a tour of the top floor, where the rooms are taking on their final shape. The building has been insulated with an open-cell polyicynene foam, earlier Steve met with its Canadian inventor. Tom and Norm are in the workshop building the last of the kitchen and bath cabinet carcasses, while landscape contractor Roger Cook works with stonemason Roger Hopkins to shape granite steps for a new walkway up from the driveway. Tom shows Steve the cementitious shingle panels being used on the garage walls, and metal fabricator Tom McGregor works on a lead-coated-copper flat-seam roof over the kitchen bay window. Finally, Tom and Norm build a fir face-frame for the bathroom vanity using pocket-screw technology.
