The builder encouraged us to go gawk at a Modern house he's building over yonder on the east side to check out his framer's work. Pretty nice. It all looked straight. Not advanced framing, but it looked like some of the corners were two-stud corners, a tenet of advanced framing to minimize thermal bridging and air infiltration. Down below is a photo of four studs, side by side where you can see clean through a gap. That's one reason why advanced framing tries to minimize the use of multi-studs.
