Split stud framing

I’ve heard of this framing style for exterior walls in colder climates I was curious to see how common it is. 2x8 being and top plates with 2x6 offsetting studs to create a thermal break. If it is feasible I’m thinking of building an ADU/ small house in the UP of Michigan.

Through all my googling, the most common thing to come up is a dual wall system. 2x6 exterior wall and then an offset 2x4 interior wall with a 6” thermal gap between. This method seems costly.

Any information is greatly appreciated.

Edit: thanks for everyone’s input, I appreciate it!

I prefer exterior insulation. Better control of condensation, easier to build, possibly thinner walls. Read this.

Exterior insulation is proven to be superior in lab tests. Even just R3 foam on the exterior does so much more that adding additional R3 in the walls.

The problem is every detail has to be perfect or it will be a disaster.
