Hello, I’m new to the forum and we are currently busy planning our first house. For cost-benefit reasons, we decided against a basement and expect the building’s exterior dimensions to be about 11 x 9 meters (36 x 30 feet). We are still in the initial planning and decision phase and have not chosen a company yet, but we have already received some house offers.
Now to the problem:
On the plot where we want to build, there used to be a house with a basement that was demolished. As a result, there is quite a large “crater” with depths of about 1 to 1.5 meters (3 to 5 feet), although the ground is very uneven. The soil mainly consists of sand and some mineral concrete.
The question that comes to mind is: since we want to build with a slab foundation, a lot will need to be done with the hole first—backfilling, compaction, etc. I just can’t imagine what extra costs this might involve, whether it will stay within a reasonable range or quickly become a five-figure amount.
One construction company even said (they know the plot) why build without a basement if much of the soil is already removed.
We are now a bit uncertain.
Hope you can help me out a little.
Greetings from Franconia

Then your sand must be very expensive. I think a ton costs about 5.50 € here.We use the organic quality Goldkorn, harvested during the new moon in the southern North Sea near the Texel plate. This comes at a slight premium. But you do feel like you’re living much better afterwards, don’t you? [emoji851]
