Configuring stairwell openning for L-shaped stairs
I'm starting to plan for the next phase of the remodelling, and I'm thinking I may be working on ceiling joists. While I'm at it, the stairs to the second floor need new treads, so between these two issues I'm considering pulling ahead a change to the stairs that will be part of the eventual second floor remodel.
Anyway, the stairway is currently a straight stair, I'd like to make it an L-shaped stairway. The sketch I made isn't entirely to scale, but it relays the concept... Do I need to have a rectangular openning which would be open beyond where the stairway is, or can it be an l-shaped openning above the stairs - and if so, is there any way to do that other than supporting it with a load bearing wall?
