Dear friends of housebuilding,
the basement has grown significantly again today. At the southwest corner, we have reached the target height of 2.5 meters (8 feet 2 inches).
Best regards
AxelAxel, it looks so small.
Does it just look that way, or is it a partial basement?

Size is always relative, as we all know. But to answer your question: The foundation slab measures exactly 85.71 m² (922 square feet). Above it are two full stories, almost identical in size. Additionally, the house will be extended on the south side by a single-story annex with a roof terrace and on the east side by an office extension. These additions also explain the question that will be answered in the next post.
Best regards
Axel

Why is there this narrow slit on the left?Hello lastdrop,
There are three narrow slits in total—one each on the south, east, and west sides. All of these slits serve structural purposes. They are formwork for pouring reinforced concrete columns, which provide the walls with extra stability when backfilling with soil.
Why is this necessary? Here’s how it was explained to me: Normally, the excavation is backfilled after the entire house is built. The structural calculations assume that the load from the walls and floors above adds additional stability to the basement walls. However, my house is designed with two extensions on the south and east sides without basements. To be able to pour the slab foundations for these extensions, the basement has to be backfilled before the upper floors are constructed. That’s why these reinforcing columns are needed.
Best regards
Axel
