http://www.AsktheBuilder.com founder, Tim Carter, shows a nifty trick when framing walls for a house. Did my video above HELP you? How about treating me to a mocha-chip ice cream cone? https://shop.askthebuilder.com/tims-tip-jar/
Don't allow an interior wall to touch an exterior wall. Leave a 3/4-inch gap so you can slide drywall in one giant piece instead of having to cut it at the corners.
This wall framing trick also helps prevent air infiltration because the vapor barrier and drywall are solid along the entire exterior wall surfaces of the entire house.
You save lumber too because there's no need for lathe catcher studs at the intersection of the two walls.
