Seasons & episodes

After a trip downtown to Tucson's Hotel Congress, built in 1919 and the site of John Dillinger's hideout back in 1934, we return to the Meigs' house, concrete pavers are laying the driveway - consistent in size but varied in color, they form a hard-wearing cobblestone-like surface.

As the Tucson project enters its final days, our host takes viewers to Biosphere 2 in nearby Oracle. Site of two experiments in self-sustained living, Biosphere 2 is now part of Columbia University's earth sciences program, serving as a laboratory for research into the effects of so-called greenhouse gases thought to be causing global warming. At the house, the finishing coat of the re-stuccoing system is going on, as well as a water-based highly reflective and waterproof roof coating. We check out a termite control system that uses insect growth hormones rather than poison, then tour the Meigs' beautiful new kitchen, complete with mesquite cabinets, black concrete counters, and gleaming stainless-steel commercial-grade appliances. We find cabinetmaker Tom Klijian behind his new library shelves-cum-powder room door. On the final day, Richard Trethewey arrives to check out the master bath, with walk-in closet with custom shelving, whirlpool bath, separate toilet/bidet room and a mahogan
