My master and guest bathroom are back-to-back (toilet-to-toilet). Both bathrooms have a tall skylight this size (~4' square). The skylights are about 5 feet apart from one-another.
I want to remove the four short walls to end up with one long smooth wall. Does the presence of a skylight nearby make these walls likely to be load bearing?
I searched and found: Are there ways to determine if a wall is load bearing?
Walls Though each wall shown runs perpendicular to the roof ridgeline, it occurs to me that taken together, they are parallel with the roof ridgeline and might constitute a supporting structure.
The closet walls have a double top plate, as shown. The East wall of the master bath is parallel with the roof ridgeline and just short of 20' long.
Attic This roof ridgeline is about 20' long here. On the South end of that ridge, the roof stair-steps down twice to an external wall. On the North end of the ridge, is a chimney and a vertical wall where this roof ends and stands above the living room roof by 2 or 3 feet. There are a few boards vertical boards in the attic that connect joists to the ridgeline, but they don't seem structural to me.
Foundation It's a concrete slab. There is no basement.
