Hey y'all..
I'm working on an old 1 1/2 story house with a finished upstairs/ attic. The "knee walls" (if you can call them that) are rather tall (close to 6') and a lot of space is wasted behind them. The plan is to build a large closet that utilizes some of that wasted space behind the wall, but also extends (minimally) out into the room.
Here's the problem I'm facing. I'm worried about disrupting any load that the knee wall might be carrying. I'm pretty sure it's not designed to be load-bearing (I very well could be wrong). Why do I think that? Well, there is no top plate (let alone two) between the knee wall studs and the rafters. Also, while the knee wall runs in the same direction as the load bearing structures on the main floor and the basement, neither the knee wall I'm working with, nor the one on the other side of the room, are aligned over the load-bearers on the other two levels.
The knee wall studs are cut off at angles and attached directly to the underside of the rafters. They all sit quite snug between the rafters & a single bottom plate, and run the full length of the house/ upstairs. Obviously the movement/weight of the roof (add in wind, snow, etc.) is a load that these studs are dealing with. How much of an issue will it be to move the support of this section back about 2'?
The closet being built will open up about 8' of the knee wall's original stud support and will occur close to the middle of its run. It will come out from the wall at almost 3' and recess into the wall a little over 2', where the new joist-to-rafter wall will be built.
Am I over-thinking this or should I be concerned about some load shifting here? If "moving" the wall isn't much of a problem causer, how would you go about constructing that new closet back wall? The same way as original, with the studs attached directly to the rafters and a sole plate? An angle cut 2X6" top plate between the studs and the rafters? No angle cut, and just a 2X4" top plate with a gap in the rafter-top plate-stud connection?
I'm sure I haven't explained this very well and would be happy to clarify anything I've left out or have a different name for than someone else in another part of the country. So please ask.
Any help at all would be greatly appreciated.
Thanks. Holden
