Building Walls for a (Duplex) House | Paul Rea

Paul Rea teaches how to build walls for a residential duplex building using 2x6 exterior walls and 2x4 interior walls. He shows the orderly sequence of the wall layout: 1) Snapping out lines for the walls 2) Cutting top and bottom plates 3) Marking the walls for windows, doors, partitions, etc 4) Moving the plates to make room for wall framing 5) Nailing the studs to the top and bottom plates. He also discusses the components of an exterior wall, why a firewall is needed, and the importance of plumbing and lining the building. See actual video of the wall components being nailed together and 6 different walls being raised up. The building is a Single Family Residence with an attached Accessory Dwelling Unit (ADU) located in Springfield, Oregon. Paul Rea is a Construction Technology professor in Oregon at Lane Community College.
