Load bearing stair components

load-bearingstairsstoragetimber-framing

I've just opened up the under stair area with a plan to convert into storage.
Can anyone tell me what parts A and E are doing in the following images? They don't appear to be load bearing to me.

I want to remove A so I can fit a door between B and C.

all parts

A close up
Doesn't look to be doing much… maybe stop the stringers from splaying in/out?

E top
I can't see how this is doing much either…

Best Answer

None of those components appear to be load bearing.

I think that the following are the possible reasons for their existence.

BCD are for attaching drywall.

E is the same (with few additional 2x4).

A is for attaching drywall with a possibility of a door or access panel.
