Hello everyone, I hope someone can help me. I have divided a gallery floor into two rooms and want to build a staircase there (it is more of a storage chamber floor with rare use, so no proper staircase is necessary). It will be a straight 17/28 staircase, 70 cm wide (as mentioned, a staircase, not a structurally removable stair) with a quarter turn (intermediate landing) made of 25 mm and 35 mm spruce. The steps will be fully closed, and the space underneath will become a built-in cupboard (whose frame could also become the "stair feet"). One side stringer should actually be fixed to the wall - but now my problems:
1.) How do I prevent creaking in a fully closed staircase (components inevitably rub against each other)?
2.) Doesn't the built-in cupboard underneath act as a gigantic resonator?
3.) Is it acoustically better for a cantilevered (or standing on the cupboard’s frame structure) staircase than fastening the stringers to the wall?
4.) Is a complete structural separation of staircase (now planned as cupboard ceiling) and cupboard possibly recommended?
So how do I reasonably make this thing quiet - thanks for the help!
