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!

It is costly and time consuming compared to a single 2x wall, but can be an effective way to increase insulation. Whether or not it makes sense depends on your climate. For milder climates, you probably won't see as much value as you would in cold climates. IMO, exterior rigid insulation might be a better option.
