General contractor Tom Silva removes the temporary support beam that has been holding up the back corner of the house. Meanwhile, engineered lumber specialist Craig Smith shows master carpenter Norm Abram the "green" framing materials to be used in t... (more)he new kitchen. Norm, Tom, and host Kevin O'Connor remove the old kitchen walls and install a new 16' beam to open up the space. Master electrician Allen Gallant shows Norm how the shoddy wiring installed over the years has created unsafe conditions and code violations throughout the house. Kitchen showroom co-owner Yael Peleg presents her vision for an "unfitted kitchen," while kitchen designer Donna Venegas shows Kevin and homeowner Maddy Krauss how the concept is incorporated into the floor plans and design choices. Back in Newton, Tom and Kevin reframe the structure of the floor under the master closet to strengthen, level, and tie it in with the rest of the floor in the new master bath.
