In the basement, plumbing and heating expert Richard Trethewey gives an update on the mechanical systems. To learn more about the home's Milford Pink granite foundation being a sign of wealth at the time the house was built, architect Treff LaFleche takes Kevin to see how the same stone was used on the Boston Public Library, and also how the granite is quarried and split to best match the home's existing stone.

Host Kevin O'Connor arrives to find most of the demolition complete, and the house entirely opened up. General contractor Tom Silva shows him the progress and then they get to work taking the dip out of the old kitchen floor by working from below, down in the basement. Inside, master carpenter Norm Abram frames up the new mudroom and powder room on the first floor using Tom's preferred method of framing up new walls: cutting all of the stock to length; assembling the walls on the floor; and standing them up one at a time. Plumbing and heating expert Richard Trethewey meets Massachusetts State Director of Flood Control, Bill Gode, to see how the Charles River has been literally formed and shaped by several major engineering projects over the years, including three major dams.

The morning starts with the arrival of a 17-foot-long steel beam that weighs 900 pounds. It will carry the load of the house over the 16-ft. opening that was made in the rear foundation wall.

On the roof at the project house in Weston, plumbing and heating expert Richard Trethewey shows host Kevin O'Connor the new solar hot water system that makes use of evacuated tube technology—the perfect solution for a cold climate. General contractor Tom Silva gives homeowner Amy Favat a progress tour of the house. The rough plumbing and electrical are nearly complete, the cabinets are in, and the concrete countertop fabricators are on site to template for the tops, which will take four to six weeks to make and to cure. At the Bensonwood shop in New Hampshire, Tom lends a hand to finish carpenter Dennis Wright as he installs "home slicker" and pre-stained white cedar shingles to the exterior wall panels.

Three weeks into the new house raising in Weston, Massachusetts, and the building envelope is almost complete. The Bensonwood crew places the last of the roof panels and sets the five-thousand pound cupola to cap off the house. The roof panels are made in the Bensonwood workshop from over fifty different structural insulated panels while crews work to apply shingles and a standing seam copper roof to the cupola before it flies. An important part of the energy efficient story with the Weston project is the new windows. General contractor Tom Silva shows host Kevin O'Connor how the windows are properly flashed and installed in the Bensonwood workshop in New Hampshire.

The second week of the house raising begins with a ceremonial timberframe raise on the first floor—by hand. The rest of the job will be done with a crane including lifting a forty-eight foot long assembly of Douglas Fir timbers and live Oak crucks that will run the length of the entire first floor. Timberframe captain Mark Roentsch shows host Kevin O'Connor how the assemblies are joined together and flow into place. Homeowner Pete Favat shows Kevin the new kitchen space, while master carpenter Norm Abram travels to Claremont, New Hampshire, to see the custom kitchen being fabricated and finished using hand-applied milk paint and distressing techniques used to make the new cabinets look at home in an "old" barn. Back in Weston the first floor exterior walls featuring windows and some finishes already installed are craned into place.

Host Kevin O'Connor arrives in Weston to find homeowners Amy & Pete Favat in the backyard, cutting back the spring overgrowth so the workers can get through. General contractor Tom Silva begins building the new house by setting the pre-cast foundation walls that are poured in a factory then trucked to the site and lifted in by crane. In New Hampshire at Bensonwood, builder Tedd Benson shows Kevin the work in the timberframe office, and demonstrates how his crew is using sophisticated software and computer-controlled cutting machines to begin fabricating over 300 timbers for the project. Back in Weston, the next step is to pour the slab for the basement and garage floor, so plumbing and heating expert Richard Trethewey installs a new insulated in-slab radiant heating system. Landscape architect Wes Wirth presents a plan for the new yard that helps deal with the wetland setbacks, excessive road noise, challenging topography, and existing garden beds.

Landscape contractor Roger Cook installs 200 running feet of pre-cast concrete to create a retaining wall that will define the perimeter of the new backyard. Inside the house, wallpaper historian Richard Nylander helps host Kevin O'Connor date and evaluate the historic wallpaper throughout the house, while general contractor Tom Silva frames for a new window in an old wall. Kevin makes a trip to Cambridge, Massachusetts, to see how three 19th century buildings are being moved as part of a construction project at Harvard Law School. The million-dollar move, which has been planned for five years, requires the buildings to be lifted and rolled down Massachusetts Avenue on hydraulic dollies steered by remote control.

Progress is made on the interior and exterior of the house. New beveled pine siding is weaved into the old. Tyler Perry Studios is toured. The house gets lightning and surge protection. In MA, The Dracut Centre School restoration is complete.

Kevin, Tom, and Charlie install a five-layer Flitch beam. Jenn watches a tree company attach a cable on an old Hemlock for support and then prune an overgrown Crabapple tree. Tom and Charlie prepare for a footing to support the corner chimney.

Richard learns about the invention of the Stillson wrench, and Mauro repairs old plaster. Norm then repairs broken balusters, and Heath installs a new panel. Venetian plaster goes on the dining room ceiling.

Kevin meets mason Mark McCullough as he starts laying blocks for the mudroom foundation. Tommy builds a custom bay window for the new kitchen. Norm visits the shop where the original windows are undergoing restoration. Tommy shows Kevin how he uses a Dutchman's patch to cover the holes left from abandoned electrical outlets in baseboards. Kevin meets homeowners Katherine and Murat at the Boston Design Center, where we meet their interior designer Amanda Reid and learn about her plans for the formal living room. Kevin finds Tommy putting in another beam to open up the front entryway.
