Space under the stairs not buildable

Hello everyone!

We are currently in talks with two different construction companies. Both know about our wish to make the space under the stairs usable as a small storage room with a drywall partition and door. One company says: we’ll do it! The other says: it’s not possible, the drywall would warp significantly because the staircase (wooden staircase) will continue to work and move for a long time. With the company that says yes, we have planned a landing staircase, with the company that says no, a straight staircase (only if that should be relevant). I have seen such rooms many times and was surprised that it should not be possible.

What do you think?

Both can be correct. With company A, I expect either larger gaps so that there is enough room for the working wood. The idea would be to have the room built only after a year, then the worst of the settling will have occurred. However, wood always works, that much is true.

Two companies? – I seem to remember you were committed to the company with the "Coburg"? – which other model are we talking about? Check in with , there are some answers about storage space under the stairs as well:

We have found another plot in the same new development. I can't name the model, as the house was custom designed. Thanks for the link! I'll browse through it!

Am I mistaken?
A staircase is not connected to the walls with wood, not even to the drywall panels. That is sealed a bit with silicone and that's it.
However, they are of course afraid that defects will be noticed again, the client will complain that the room is not properly sealed, etc. I can understand that.
Still, have it done – the drywall installer is your friend ;)

It would be a staircase with risers. Also wooden. Could that perhaps make the difference? But your statement gives me courage, because we would really like to have that room under the staircase.
