The show begins with the TOH guys antiquing and then heading over to the jobsite on Monterey Square. With demolition of the rear porches complete, the Turner Construction team, led by Mark Fitzpatrick, has moved on to framing, using engineered lumber where possible. Mark tours the project from garden-level apartment to roof. We visit the next door twin of the Flemings' house for clues about its original floors, lighting, mantlepieces and archway between front and rear parlors. Homeowner Mills Fleming and designer Jeff Verheyen review some of the changes - mainly in bathroom placement, number and design - that have occurred since the original blueprints were drawn up. Meanwhile, plumbing contractor Ernest Hutson shows us how to vent an understairs powder-room toilet with an air-admittance valve that precludes the use of a through-the-roof vent. Viewers then tour the architectural and plumbing splendors of the Owens-Thomas House, an outstanding example of the English Regency style built
