I'm at a loss here (?)
Yes, when experimenting you can easily get the straight staircase right, but the basement access then quickly ends up in the living room or somewhere else. In any case, it's not easy, which the architect, if you can call him that, has probably already noticed.
I saw something recently, maybe that would work: once with and once without an office, where the door to the office could also be or better from the hallway.

The basement access is located under the other staircase with a 1/4 turn at the start.
Since we basically don't know anything here (building window etc.), it's just guessing. Here again is the questionnaire. Just copy and fill in the answers:
