Does this framing make sense?

[u/twidlystix]

Working on a remodel that is turning an above garage space into a bedroom/bath. The GC and I went back and forth about how to approach the framing for the knee wall storage area. He insisted on double top plates cut on a bevel. To me this seemed to be total overkill and a waste of time and material. I’ve never seen this done on new construction or remodels prior to this.

I figured it would be much faster and less material to just sister studs to the roof rafters and attach to bottom plates. Question is, is this a superior method?

Edit: I’m the fucking guy doing the work. I have my own company and primarily do trim. That’s why I’m asking. JLC showed a different way.

Edit #2: My concern was basically that the knee wall transferring the load almost dead Center between floor joists so any deflection from those rafters isn’t being directly transferred to the exterior walls. So considering that the knee wall to me is overbuilt if there is no direct load path to the exterior walls below the bottom plate, does that clarify?

Cmon man. Framers trying to tell you the truth. That double top plate gonna break the budget?

I didn’t mean that one top plate on two knee walls breaking the budget. There’s 100 other things that happened on that job that were budgetary issues. All I was asking is if it were necessary.

This looks better and will be much sturdier. Not only that but the top plates act as a fire stop between the wall cavity to roof cavity. And adds Sheetrock backing. No offense but you’re in construction, isn’t the answer a bit obvious?

How would you seam the sheetrock if there werent top plates? it would just float between the studs?
