At the project house, master carpenter Norm Abram meets contractor Michael R. Streaman and homeowner Karen Shen to see how the framing is progressing and to hear about their thoughts on the kitchen layout. To learn more about how brownstones were used in the past, architectural historian Charles Lockwood takes Kevin to Manhattan's East Village to see a perfectly preserved rowhouse dating to 1832, including the original intact kitchen in the basement. Then, to see how the old-fashioned spaces can be updated, they visit a restored brownstone in Park Slope, Brooklyn, to see how former kitchens were often converted into rental apartments, and how modern kitchens and baths can be either carved out or bumped out from existing spaces.

For the first time in the show's history, host Kevin O'Connor and master carpenter Norm Abram take This Old House on the road to New York City to restore a neglected 1904 brownstone in Brooklyn. Homeowners Karen Shen and Kevin Costello will convert the former rooming house into a three family home while preserving and restoring period detail wherever possible. In Brooklyn, Norm meets veteran brownstone remodeling contractor Michael R. Streaman at a similar job down the street to see how he transformed one of these rooming houses into a beautiful, modern family home. Back at the project house, Streaman gets to work on demolition and also starts stripping the paint off the back of the house to prepare the brick for re-pointing and eventually the installation of new energy-efficient windows.

At the project house in Weston, landscape contractor Roger Cook tends to the last efforts on the landscaping front, which includes fresh sod, a bocce court, and a new irrigation system.

In the master bathroom, tile contractor Mark Ferrante lays the last of the handmade tile over the new cast concrete vanity sinks. Finishing touches are put on the security system and industrial light fixtures, and the signature "harvest table" (designed by architect Chris Adams) is delivered for dining room.

At the project house in Weston, landscape contractor Roger Cook installs a berm and fence in the front yard to screen out the busy street. Landscape architect Wes Wirth and homeowner Amy Favat review the native plants they've chosen for the new planting beds. Amy takes host Kevin O'Connor to a showroom and workshop in Florence, Massachusetts, where they both lend a hand in making the concrete countertops and sink. Back in Weston (after a 30-day cure time) master carpenter Norm Abram finds the countertops being installed in the kitchen. Plumbing and heating expert Richard Trethewey shows Kevin how the house is being cooled, with an a la carte, split-type air conditioning system featuring outdoor heat pump units and indoor wall mounted units. These provide zoning control in the different areas of the house. Upstairs in the master bedroom, Kevin finds Amy and designer Carole Freehauf putting down eco-friendly carpet tiles that are easy for DIY-ers to install.

At the project house in Weston, landscape contractor Roger Cook installs granite steps on the entry porch, precast footings for the pergola, and Goshen stone for the front patio.

Meanwhile, in Brookline, New Hampshire, master carpenter Norm Abram meets third generation lumber and paneling expert Tom Bingham to see how he is making custom wainscoting, chair rail, and horizontal wallboards for the Weston home. Back in Weston, Tom shows homeowner Pete Favat the new custom garage doors and how they are installed and operated.

Homeowners Amy and Pete Favat are on site in Weston for the first day of "raising" their new house but the excitement is soon tampered by unexpected rain. After a two-day rain delay, the Bensonwood crew begins by craning in and setting the mechanical room module and all of the walls for the basement level. In the New Hampshire workshop, plumbing and heating expert Richard Trethewey and mechanical systems manager Paul Boa fabricate the floor panels and add radiant heating and insulation in the comfort of a controlled environment. Back on site in Weston, the completed floor systems are craned into place. Despite continued rain, the crew manages to close in the basement level, and Amy gives host Kevin O'Connor a tour of the amenities on that floor—parking for two cars, a mudroom, workshop, powder room, kitchenette, and media room.

For the new season, host Kevin O'Connor and master carpenter Norm Abram reveal that This Old House will be building new—a prefab, eco-friendly home that will feel like an old barn. Homeowners Amy & Pete Favat love their land, but have outgrown their 1970s-era home, so they'll deconstruct the old house to make way for a new one that will better suit their active family. To achieve their vision of a vacation home "all year round", custom homebuilder Tedd Benson and his staff are designing and prefabricating the new state-of-the-art timberframe home, with general contractor Tom Silva pulling it all together on site. To see how Tedd's panelized system looks in the field, Norm and Tedd visit a recent project in Center Harbor, New Hampshire, while back in Weston, Tom works with deconstruction contractor John Grossman to take the old house apart by hand, in a way that saves landfill space, and allows the reuse of building materials.

To replace the stairway he removed from the old kitchen, general contractor Tom Silva builds a brand new stairway to the basement. Then, plumbing and heating expert Richard Trethewey shows host Kevin O'Connor how to select a good quality faucet—discussing function, finish, construction and valves. Inspired by an existing arched door opening, Tom shows Kevin how he's making a vaulted ceiling in the hallway that connects the front of the house to the new addition out back. At the end of the day, insulation contractor Tony Trigler arrives to install spray foam insulation in the new addition.

After a brief stop at Johnny's Luncheonette for breakfast, host Kevin O'Connor meets paint color specialist Ann Pfaff to learn what colors might be appropriate for the Shingle- style house.

In the South End of Boston, Kevin visits stained glass designer Jim Anderson at his workshop to see the restoration and rebuilding of the home's four historic windows. In the home's backyard, under the new porch, landscape contractor Roger Cook uses a pay-as-you-go concrete truck to pour a small buttress wall that will support the exposed rubble stone foundation.

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 the 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.

Master carpenter Norm Abram and general contractor Tom Silva remove the old vinyl siding from the exterior of the house, exposing not only the original wood clapboards underneath but also lots of repair work that needs to be done. Inside, architect Paul Rovinelli takes host Kevin O'Connor and homeowner Gillian Pierce through the plan for the new kitchen, which calls for a modest expansion, building as Gillian puts it, "just what we need," and nothing more. One early proponent of that style of thinking was architect and author Sarah Susanka, so Kevin travels to her own "Not So Big" home in Raleigh, North Carolina, to see some smart ideas for restrained remodels that won't break the bank. Back in Newton Centre, landscape contractor Roger Cook breaks up the old porch slab to make way for the foundation for the new addition.

Master carpenter Norm Abram and host Kevin O'Connor open the show at Cambridge Common — the city's oldest public open space and a center of rebel activity in the early years of the American Revolution. Back at the project house, Kevin lends Norm and general contractor Tom Silva a hand framing in the "not quite flat" roof above the library — it has a slight pitch to shed water. Plumbing and heating expert Richard Trethewey shows Kevin a new software program that allows him to design the HVAC system on a laptop and run heat loss scenarios for the house while changing variables like windows, insulation, and various kinds of ductwork and heating. Landscape contractor Roger Cook brings homeowner George Mabry to one of the largest stone yards on the East coast to begin selecting hardscape materials for the landscape.

He then finds the homeowners meeting with architect Mat Cummings, who has put together a couple of color-scheme options for the exterior of the house. Richard travels to New Bedford, Mass., to see the claw-foot tub undergoing restoration. Electrician Allen Gallant shows Kevin the remnants of old knob-and-tube wiring and snakes new wires for new fixtures in the master suite. Tommy uses a custom-made knife to shape new molding that matches the existing exterior molding.

A basement door is concealed; the new Cararra marble island top is spotlighted; a PVC fence is installed on top of the retaining wall; the front steps are given new life with a grinder, a router, epoxy and non-slip exterior paint; and the salvaged marble mantel and surround are installed in the sitting room. Also: the transformation of a Boston lighthouses into a summer home.

Kevin and Roger dig the Essex clamming scene out on the flats, then are regaled with some world-famous fried clams where they were invented a century ago: Woodman's of Essex. Norm drives up to the project house to find the infrastructure work (finally) settling down outside, and reminds us that we're designing for one-level living. Inside, on the day before spray foam insulation, he reviews the floor plan while Richard provides an update on rough plumbing and ductwork progress. Challenges include running vents to the backside of the house and getting ducts up into the steeply pitched roof spaces. Radiant floor panels are going down on second floor. Back outside, Norm finds roofer Dennis Gannet and his daughter Sarah Gannet installing the standing seam metal roof. Back on the front side of the house, Kevin finds Roger halfway through the front walk.

Host Kevin O'Connor arrives to find the job nearing completion thanks to the dedication of general contractor David Lopes. Landscape contractor Roger Cook and the YouthBuild apprentices plant the final tree and spread mulch out front, while out back, fence contractor Mike McLaughlin installs the entry gate on the perimeter fence. Inside, designer Tricia McDonagh is readying the house for the wrap party, as the final light fixtures and window treatments are installed. Down in the basement, local HVAC contractor Abdul Barrie gives homeowner Lanita Tolentino a crash course on what she needs to know about the mechanicals in her basement. Boston Mayor Tom Menino stops by to see how the house turned out, and while work continues on the second unit, Lanita’s unit is ready for her to move in. Upstairs, she shows Kevin the tile and fixture choices in the bathroom, and also her spacious new bedroom and walk-in closet.

With just one week left in Roxbury, tile contractor Angelo McRae shows Kevin how to install meshed white subway tiles with a rail cap for the kitchen backsplash. Kevin visits our Washington, D.C. project house to meet the family that moved in and see how our last venture in non-profit development turned out. Then, general contractor Tom Silva lends a hand to lead carpenter Colin Paterson, who is customizing and installing the stair treads and newel post for the new stairs.
