The show opens with a walk along a newly restored natural corridor lining the banks of the Charles River in Watertown. The result of years of hard reclamation work by the Metropolitan District Commission, it forms part of an unbroken systems of walk and bikeways stretching from the mouth of the river west to Waltham. Back at the house, the crew opens up a water-damaged corner of the building to find rot, carpenter ants, and termites, Homeowner Christian Nolen is presented with a plan to heat and cool the building efficiently, while still using the existing ductwork. Our host visits the Browne House, circa 1690, the oldest house in Watertown, and one of the first restoration efforts by the Society for the Preservation of New England Antiquities. At the site, historic preservationist Andrea Gilmore explains the architectural features that make our subject house a Queen Anne Victorian, and she reveals its original colors.
