At the project house in Weston, landscape contractor Roger Cook installs a berm and fence in the front yard to screen out the busy street. Landscape architect Wes Wirth and homeowner Amy Favat review the native plants they've chosen for the new planting beds. Amy takes host Kevin O'Connor to a showroom and workshop in Florence, Massachusetts, where they both lend a hand in making the concrete countertops and sink. Back in Weston (after a 30-day cure time) master carpenter Norm Abram finds the countertops being installed in the kitchen. Plumbing and heating expert Richard Trethewey shows Kevin how the house is being cooled, with an a la carte, split-type air conditioning system featuring outdoor heat pump units and indoor wall mounted units. These provide zoning control in the different areas of the house. Upstairs in the master bedroom, Kevin finds Amy and designer Carole Freehauf putting down eco-friendly carpet tiles that are easy for DIY-ers to install.
