This Old House is in Cambridge, Massachusetts, where the crew will turn the inside of a dark, divided 1887 two-family into an open, Scandinavian-style one-family. Kevin O'Connor tours the house, while Roger Cook finds surprises outside. Richard Trethewey does an eye-opening energy audit. Architect Marcus Gleysteen shows Kevin his Scandinavian-style home. Tom Silva brings in deconstruction experts to remove unneeded parts, carefully peeling back the layers.
