A different way to frame. Is this a terrible idea?
I had this strange idea for a framing method that eliminates a lot of thermal bridging and makes it much easier to run pipes and electrical, eliminating drilling through studs. Just curious if it makes sense at all to ever do a wall like this.
It would consist of 2×6 top and bottom plates using 2×4 studs that stand across from each other, oriented perpendicular to the standard direction, 24″ OC.
This provides a 2.5″ gap that can be insulated and blocked where necessary for support and for required, deeper fasteners. The blocking could even be oriented like a standard stud using 2×3’s where needed, and obviously not spanning the entire height of the wall to allow for rough-ins.
Would orienting the studs like this make for a weaker wall? What are the biggest problems for a wall like this? I feel like it must have been considered at some point. Thanks.

Flat studs are not permitted by code.
It would certainly make a weaker wall. Also more warping. Greater minds than mine might justify it but I don't like it.
Flat studs are not permitted by code. Although you could stagger studs on each side like in a party wall.
Better idea - use metal studs. Someone, a lot smarter than me, has already done the research and design development.

There's now a product admitted by code (in some places) that uses flat studs and structural pieces between them at intervals. It takes into account the design positives you have here, and also also addresses the lateral strength. So I'd argue your thinking is good, but it needs additional engineering considerations.
My advice is to ignore those with the immediate answer to any new idea: "nope, no code" and continue to think about creative designs. Look for encouragement from the few, not the many.
tfarwell,
So glad somebody said it. The code is to try to limit serious mistakes, not to crush innovation.
I don't know about code as others have referenced. I have often framed plumbing walls using flat studs with 2x6 or 2x8 plates with a couple of plywood gussets tying the studs together and was never flagged.
The biggest reason for not using this system through out the house is simply that it would require twice as much material and labor.
Double stud walls are a reasonable approach to eliminating thermal bridging and they're used in a lot of high performance houses. However, as others have pointed out, flat studs aren't to be used in a structural situation. Here's a link to an FHB webinar from the authors of the article on double-stud walls in the most recent issue.
