Advanced Framing – 2 ft module from exterior or interior perspective?
Hopefully this has a simple and obvious answer, but nothing I’ve read so far has touched on this.
One of the cornerstones of “advanced framing” is that everything is built in 2 ft “modules”, that way so many thing just fit without having to be trimmed. But is the 2 ft module width from the perspective of the exterior or from the interior?
I’ve attached a quick mockup of what I’m talking about.
For the left and bottom walls, I prioritized the exterior and so you can see that all of the 2×6 studs are in 24″ O.C. The bottom wall is 8′ long and I could just grab a sheet of OSB and screw it into place without any cuts at all. Nice.
But look at the inside of that room. All of the dimensions are going to be off by the 5-1/2″ width of the wall itself and so now I’m having to have custom fitted drywall in every corner. It’s not a standardized module size at all.
If I did prioritize the interior, though, then it would look like the right wall. In that case, I have standardized 24″ O.C. widths for my drywall, negating any need to cut it… but now that extra 5-1/2″ is tacked on to the exterior sizes. Cuts are now mandatory there.
So… when we’re talking about 2 ft modules, it is standardized on the exterior or the interior?
(Or am I missing something fundamental and my entire question is moot?)
