Outdoor stairs/Staircase entrance bungalow

Hello everyone, we are currently facing a problem. Our bungalow was built into the hillside, so our basement is at ground level. We have 2 entrance doors. The first leads to the basement + [Einliegerwohnung] and the second to the bungalow above. Now we are desperately looking for a solution to get to the 1st floor (bungalow). The house itself has more of a country house style, so a metal staircase – I already had a few designs on the table – looked like a fire escape. Wood is actually not an option for us, as it is too maintenance-intensive.

Does anyone have ideas on how to best design/plan the staircase to get to the 1st floor? We have also thought about a prefabricated concrete staircase with a landing, but we are really not making any progress here.

Suggestions with pictures are also welcome.

Thank you very much!

Floor plans and pictures would also help a lot to understand the problem and find a solution

Outdoor or indoor staircase? Construction already finished or still in planning?

This is the house and we would need to go up to the first floor via an external staircase.

Just ask the one who planned it that way. How do you currently get to the 1st floor?

Sorry, but who planned this? An internal staircase would be appropriate here or the front door for upstairs somewhere on the slope. An external staircase here will always look like an emergency solution and be impractical.
