Richard tours a neighborhood curiosity: a water tank disguised as a Greek temple. Tom and Kevin make some dramatic discoveries while demolishing the kitchen and baths, Roger moves a massive rhododendron and Norm checks out one of the finest surviving examples of the Italianate Style: the over-the-top Victoria Mansion in Portland, Maine. In the second half of the hour, on ASK THIS OLD HOUSE, Roger visits New Mexico to install an irrigation system designed to work in a desert climate. Richard installs a new style of heat-pump water heater. Tom shares a viewer tip about re-using an old garden hose reel. And the guys ask, "What is it?"
