Floor plan design for a two-family house on a slope

We have the belt-suspenders variant WU-wall, then bitumen coating, insulation outside, insulation inside Super if you have a staircase soon

And now the preparations for the ceiling KG are underway.

There it lies already! The ceiling on the basement. This week, the walls will then be filled about 2/3 with concrete. Then it's carnival time for now. Next Friday, the ceiling is supposed to be poured. Currently, the western outside staircase is causing problems. Originally planned as a precast concrete part, it apparently cannot be placed there using a crane. Now a cost comparison is being made against on-site formwork.

Yesterday we were able to briefly enjoy the view from the future terrace on the ground floor!

"There used to be more tinsel," but less iron. Attached is a picture before concreting the KG ceiling and a picture after the last concrete pour. If that doesn't hold, they are definitely calculating with a safety factor of 5.

Counted at least with 5. It was the same for us. I believe the retaining wall and the floor slab are sufficient for a bunker.
