Plot: It's a wrap for the This Old House East Boston project! After a short ride on the Blue Line - the first subway in the world to run underneath a section of the ocean - master carpenter Norm Abram and host Kevin O'Connor arrive in East Boston to find furniture being delivered, a tent going up, and flat screen TVs being installed. Upstairs, custom cafe shutters complete the casual, cottage look for homeowner Chris Flynn, while downstairs, the grout on the glass tile backsplash is being finished in the first floor unit
