Host Kevin O'Connor arrives to find general contractor Tom Silva meeting with building inspector Michael Grover. At the front door, Tom shows Kevin how he's installing the brushed nickel mortise lockset on the custom oak door. In the basement, plumbing and heating expert Richard Trethewey shows master carpenter Norm Abram the mechanical room —highlights include a gas fired boiler, three different temperatures of radiant heat (for ice melt, under floor, and over floor), an HRV for fresh air, and a fine mist humidifier to add a touch of moisture to the building. In the kitchen, Norm finds carpenter Charlie Silva installing the custom cabinetry and scribing the base trim to the irregular bluestone floor. Out back, irrigation system specialist Ed Marchant shows landscape contractor Roger Cook the features of the new irrigation system. Kevin sees the new modern closet systems from Italy being installed in the master suite.
