I just moved into a new place and really want to move my awesomely large (and somewhat expensive) sofa into the basement. The problem is that the stairs end in narrow hallway running perpendicular to the stairwell:
There is not enough room to get the sofa down the stairs and around the corner to the right without modifying the structure:
I'm wondering if it's (a) possible and (b) not entirely stupid to temporarily remove the bottom stairs and carpet cover to accommodate the size of the sofa:
The crawlspace floor is directly below the stairs, so I can access them from underneath if necessary. I'm also open to other suggestions. The only other entrance into the basement is through a window that is too small for the sofa.
Update:
Here is a picture of the underside of the stairs:
