This Old House Season 29 Episode 4 Newton, MA 04

With the new framing in, Tom and Kevin remove the temporary support beam. Norm talks with an expert about engineered dimensional lumber. Tom and his crew open up the kitchen, removing walls and replacing them with posts and an engineered beam. Master electrician Allen Gallant discovers some very poor wiring in the attic (perhaps a handyman special) and decides the best solution is to rewire the third floor. Kevin visits a kitchen showroom where he learns about trends in kitchen design: the 'unfitted' kitchen and kitchen workstations for specialized tasks. He returns to discuss the kitchen for this home with designer Donna Venegas. Before extending the master bedroom into the former porch space, Tom and Kevin cut out the old joists (which are too few and have a pitch) and replace them with engineered joists.
