This Old House opens a new season with work on a 300-year-old farmstead that is rich in Colonial history. Homeowners Joe and Becky Titlow plan to preserve the historic part of the house while adding space and modern amenities with two small additions. Architect Dan Quaile presents the plan using a remarkable model generated from a 3-D printer, while general contractor Tom Silva inspects the structure and historic window sash, which will be restored. In the basement, plumbing and heating expert, Richard Trethewey, finds the relic of an antique water pump system, and a newer mechanical system that contains some inefficient and unsafe aspects. Master carpenter Norm Abram is concerned about the high water table, especially when it comes to excavating for the new additions. Landscape contractor Roger Cook considers the half-acre lot and what the homeowners would like to add—a storage shed, raised garden beds, a new driveway, and stone walls. The bulk of the landscape work will be clearing a

Landscape contractor Roger Cook starts by transplanting the shrubs and plants from the front of the house to a place where they can be "heeled in" for safe keeping until the job is complete. Homeowner Joe Titlow shows host Kevin O'Connor how his company builds highly detailed architectural models (and a whole host of other useful items) by printing them with a 3-D printer. Then, Roger gets to work clearing the small trees and overgrowth that are in the way of the new family room addition. Near the oldest part of the house, Kevin and master carpenter Norm Abram dig in by removing the front entry porch and the accessibility ramp. Then, in accordance with the new EPA lead paint laws, they set up to begin removing the peeling and rotted clapboards. Out back, general contractor Tom Silva shows Kevin how he's laying out for the new addition, and excavation begins. As expected, water is discovered, and Roger gets to work setting up a drain and sump pump system to deal with it. Mason Mark McCu

Host Kevin O'Connor meets with landscape designer Jenn Nawada Evans to see her plan for the rambling site.

Host Kevin O'Connor arrives to find the new family addition framed up and sheathed using something fairly new – a coated OSB product that has the properties of a house wrap built in.
