Height is 30". I want to install some type of heavy-duty slide-out shelving, but I have the supporting 2X4 that splits the space in half. I prefer to have one shelf, not two, so can I remove the 2X4" and replace it with some type of additional support e.g. along the sides of the crawlspace?
The answer is YES. Anything is possible. The question relates to how far you're willing to go to remove the 2x4.
If it's supporting the middle of the top of the stairs - which it appears to be - you can do what others have suggested with jack studs and a header. It's also possible that you can shore it up by other means.
Any possibility you can shoot us a picture of the INSIDE of that nook - where the 2x4 actually attaches to the stairs?
