Framing a walk-out basement

I've been reading on this forum that the preferred way of framing a basement wall is to just build a freestanding wall an inch from the exterior basement wall. This approach seems sensible, but I'm wondering whether it'll work for my application.

I have a walkout basement, so my south and west walls aren't entirely concrete. The east edge of my south wall is concrete up to the ceiling, but it shortly turns into 2/3 concrete with the top third being 2x4 studs and insulation -- then it drops to 1/3 concrete and 2/3 studs, and finishes as a fully studded wall on the west edge, complete with a couple of traditional windows built into the wall (at normal living-level height).

How should I finish that wall?

 

You have some choices here. You can frame it out so your walls are all the same, or just frame out the concrete, with a large shelf on top of your concrete. Since you have windows, I would not frame out the 2x4 portion unless you want to build your windows
out the additional width. Good Luck
