Hello everyone,
I plan to build the unoccupied ground floor (storage area) with a height of 4.5 m (15 feet) so that the upper level has a ground-level exit. The property is on a slope. The project is still in the early planning stages.
Would you prefer double concrete walls, cast concrete walls, or concrete block walls?
Does anyone have experience with double concrete walls? What are the current costs? Unfortunately, I couldn’t find reliable prices online.
Cast concrete walls would also be great, but this would need to be fully contracted out.
Building the walls yourself with concrete blocks would also be a solution, but I think it would take too much time!
Thanks for your input!
Best regards,
Hickorie

@Hickorie that would be quite sloppy and has nothing to do with proper waterproofing.
With many compromises, your budget might possibly cover a 150 m2 (1600 sq ft) bungalow but not the basement, excavation, and other additional costs.
Especially in Bavaria, where, as in Baden-Württemberg, prices are highest.
A rough estimate for the basement alone is around 40,000 to 50,000 EUR by the time it’s completed.
What about the excavation? Will it remain on the property or does it need to be disposed of? Do you already have a soil survey?
It sounds like this is still just an idea and that no planning has been done yet....

It is often much cheaper to construct only the upper of these two virtual basement levels as a proper basement (using traditional masonry construction) and to fill the space below with a 2m (6.5 feet) high layer of mineral aggregate.
Basement walls in contact with the soil must withstand lateral earth pressure. The taller the wall, the more likely it is to buckle. This means either many internal walls acting as supports for the outer walls, multiple ring beams in between, or other solutions. I believe this could be beyond the capabilities of typical single-family home builders. This is industrial-scale construction.
