Looking for ideas for stair solution/replacement

Hello,

we have bought a little house and now want to address some structural issues in addition to the energy renovation.

Regarding the attached picture, my question:

As it currently appears, the garage integrated in the basement is only usable to a limited extent. The picture was taken from the garage opening and it is only 3.86 m to the start of the stairs. Between the left wall and the stairs there are 2.35 m. This would mean that the car would have to be parked slightly diagonally and since the garage door opening is quite narrow, at least my wife would definitely have a problem with it.

The easiest solution in my estimation would be to tear down the side wall of the stairs and install a winder staircase rotated 180 degrees and then drive with the car hood under the staircase slope. But then I would run into the wall upstairs in the ground floor. So I need about 90 cm more space, but the stair opening cannot be enlarged due to the room layout on the ground floor.

The idea would be to install a U-shaped staircase with a 90-degree turn at the beginning and end with a somewhat longer middle flight and have the first two steps cantilevered into the space under the stair opening so that the head clearance of 2 m is still sufficient. I have found 2 online calculators at Treppenportal and Kalk. Are there any others, better ones, where I could try this out?

Does anyone have another/better idea on this?

Thank you,
Dirk

Does anyone have another/better idea about this?

1. Elevator
2. Why not just a simple spiral? Then the stairs would end at a 90-degree angle to the wall, but I wouldn’t find that bad. Could that work?
3. Spiral staircase

If it’s just about getting to the basement/the garage as simply and easily as possible, I would choose number 3. Takes up the least space.

Hehe, you forgot teleportation and fireman's pole..

No, elevator is out, I have agoraphobia in my wallet
For simple winding, the stair opening is probably too small. I have to check that after the purchase, when I have the keys and will check everything in detail.
Spiral staircase is also rather out, since the stairs to the upper floor are above and should be easily walkable for my parents (over 70). I really can't imagine a normal staircase over a spiral staircase.

What is in the room next door? Can't the staircase be extended there with a 90° turn?

That would probably be possible by inserting a new (wider) beam, but you don't gain that much space just from the turn alone. And more than 2 tapering steps don't fit because of the headroom anyway. So I would gain a maximum of 1m with that. But I still need to look at it in detail to see if the length would then be sufficient.

The staircase already seems quite steep to me... then adding a winding to it... hmm... where does it lead? Into your main hallway? Otherwise, I have to say as a woman: I don't see the problem with reversing into a parking space. You can practice something like that, especially if a rearview camera isn't installed. I think it's a load-bearing wall, as you can see.
