I have a staircase leading upstairs directly above another staircase leading to my basement. I’m trying to find a way to remove or replace the center stringer of the upper staircase so I don’t have to duck every time I need to go to the basement. Both outer stringers are supported by walls or at least they will be once the project is finished.
Treds: 1′ x 10’x 28′
Risers: 3/4 x 8 & 3/8 x 28′
I may also distance the stairs below by moving them out and dropping them by one step. I’m looking forward to any advice or alternatives I can use for safe and sound results.
