On our last day in Key West, viewers get a look at the new pool, its cleaning system and the heat pump that both heats and cools it. (Key Westers have to chill down their pools during the brutal summers.) Inside, we see the handiwork of tileman Tom Lapp, who is putting the finishing touches on a beautiful entryway of black and white, concrete Cuban tiles. Outside, painter Perry Fergus and crew are using a latex topcoat for the house's body and trim, and a high-gloss oil for the new shutters. Vierers then visit the local shop where they were made. Back at the house, lead carpenter Bev Horlick installs the first of several mahogany French doors made by the same shop, using heavy brass hinges and tarnish-proof handles. Our host checks out the new lanscaping with contractor Mari Blair, who has used a variety of native plants, an irrigation system and low-voltage lighting. Our master carpenter agrees with homeowner Michael Miller that rushing the cabinetry in the library is not a good idea,
