Hello,

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

Regarding the attached picture, my question is:

As it currently stands, the garage integrated into the basement is only partially usable. The photo is taken from the garage entrance, and it is only 3.86 m (12.7 ft) from there to the start of the stairs. Between the left wall and the stairs, there is 2.35 m (7.7 ft) of space. This means the car would have to be parked at a slight angle, and since the garage door opening is quite narrow, my wife would definitely have an issue with that.

In my opinion, the easiest solution would be to remove the staircase’s side wall and install a winder staircase turned 180 degrees, then park with the car’s hood under the stair slope. But that would cause me to hit the wall upstairs on the ground floor. So, I would need about 90 cm (35 inches) more space, but the stair opening cannot be enlarged due to the room layout on the ground floor.

The idea is to install a U-shaped staircase with 90-degree turns at the beginning and end, with a slightly longer middle flight, and have the first two steps cantilever into the space under the stair opening so that the headroom of 2 m (6.6 ft) is still usable. I found two online calculators on Treppenportal and Kalk. Are there any other, better tools where I could try this out?

Does anyone have any other or better ideas?

Thanks,
Dirk

1. Elevator
2. Why not just a simple winding staircase? It would end at a 90-degree angle to the wall, but I wouldn't mind that. Could that work?
3. Spiral staircase

If the goal is just to have a straightforward and space-efficient way to get to the basement/garage, I would choose number 3. It takes up the least space.

Hehe, you forgot teleportation and a fireman’s pole.

No, an elevator is out of the question—I have agoraphobia in my wallet.
A simple spiral staircase probably won’t fit because the stairwell opening is too small. I will need to check this after the purchase, once I have the keys, and examine everything in detail.
A helical staircase is also unlikely since the stairs lead to the upper floor, and it should be easy for my parents (over 70 years old) to use. I can’t really imagine a regular staircase over a spiral staircase.

What is in the adjacent room? Could the staircase be extended there with a 90° turn?

That would probably be possible by installing a new (wider) beam, but you don’t gain much space from just the landing. Also, more than two tapering steps won’t fit due to headroom restrictions. So, I would gain at most 1m (3.3 ft). I still need to look at the details to see if that length would be sufficient.

The staircase already seems quite steep to me... and then adding a spiral to it... hmm... where does it lead? Into your main hallway? Otherwise, as a woman, I have to say: I don’t really see the problem with reverse parking. This is something you can practice if there isn’t a rearview camera on board. I believe this is a load-bearing wall, as you can see.
