ᐅ Realistic Costs for a Basement Near Regensburg?

Hello everyone,

I need your advice.
We have found a plot of land near Regensburg with a developer tie-in.

The offer includes a slab-on-grade foundation without a basement, valued at €25,000.
Alternatively, we requested a quote for a waterproof basement (WU) priced at €1,200 per square meter (including the ceiling).
Additionally, there are €18,000 for excavation work related to the basement.
With a basement area of 60 square meters, this would amount to €72,000.

So our costs would be:

€72,000 for the waterproof basement
€18,000 for excavation (soil class 6)
€25,000 for the slab-on-grade foundation
= €115,000 for the complete 60 square meter basement.

Is this realistic?

Best regards

So, we had a budget of 100k for the basement:
80k for the basement structure
21k for the earthworks

The slab foundation should be the alternative and not an additional cost, right?

The difference would then be
100k for the basement compared to 25k for the slab foundation + 5k for earthworks.
So, with a basement, it’s roughly 70k more expensive.

Thanks for the reply. Yes, that’s exactly what I thought as well, and that’s what’s making me suspicious 😕

Does it only seem excessive to me to pay 1200 per square meter plus groundwork? Or are all the construction companies just going crazy right now...?

What about soil removal? That should at least also be included in the additional construction costs when comparing slab-on-grade foundation vs. basement.

The concrete slab is not omitted; it is just positioned deeper (below the basement walls)???
