This Old House - Season 27 Episode 4 Cambridge | Longfellow's House
5.20 30 minutes Host Kevin O'Connor and master carpenter Norm Abram visit the independently owned neighborhood shops of nearby Huron Village. Back at the house, Kevin lends Norm and general contractor Tom Silva a hand jacking up the old floor joists of the future library to make it level with the floor of the new addition. Landscape architect Gregory Lombardi presents a plan for the front yard featuring stone walls and courtyards organized around a water feature. Certified arborist Jack Kelly shows landscape contractor Roger Cook a treatment of horticultural oil that will protect the property's hemlocks from a fatal infestation of wooly adelgid. Down the street, Kevin meets curator Nancy Jones for a tour of the legendary Longfellow House. Built in 1759, the Georgian-style home has been lived in continuously for 250 years by luminaries such as General George Washington and poet Henry Wadsworth Longfellow.
