Jacking up the old floor joists of the future library to make it level with the floor of the new addition, a plan for the front yard and a treatment of horticultural oil that will protect the property's hemlocks.

Host Kevin O'Connor and master carpenter Norm Abram get a feel for the neighborhood by visiting the independently owned 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.
