Hello everyone,
I am interested in whether it is possible to make general statements about costs in relation to the following cases:
1. Fully basemented vs. half basemented
2. A full upper floor vs. an upper floor that is only half the area of the ground floor
Please assume the same basic conditions in all cases, and an average single-family house with typical factors (location, soil, wall construction, etc.). I understand that many factors influence the exact costs, so I am not looking for precise figures. A rough estimate would already help, for example if it can be said:
“Half basemented costs about half as much as fully basemented.” Or is it more likely that the difference is not that significant because some costs are fixed and then spread over a larger basement area when fully basemented? So maybe it is more like: half basemented: 20,000 EUR, fully basemented: 30,000 EUR?
I would be interested in the same calculation for the upper floor. Is there a noticeable saving if, for example, in a Bauhaus style with a flat roof, you have a 100m² (1,076 sq ft) cube as the ground floor and place a 50m² (538 sq ft) cube as the upper floor on top? Compared to a 100m² (1,076 sq ft) ground floor with a 100m² (1,076 sq ft) upper floor?
Many thanks

Regarding “general statements,” I can share what I have often heard about basements:
Partial basement:
You either build with a basement or without. The additional cost for a partial basement is relatively small.
Basement or not:
If you need the extra living space and the lot size is limited, you opt for a basement. For storage space alone, a basement is too expensive.
Costs for a basement:
Highly variable depending on size and requirements (waterproofing, insulation, windows, etc.). When comparing, don’t forget that the alternative concrete slab also comes at a cost.
The additional cost for a basement in most single-family homes is probably between 30,000 and 50,000 euros.
We need the space, so we planned with a basement. It is cheaper than adding a full additional floor (if that is even allowed).

The statement "It will be cheaper than adding another full floor (if even permitted)" is, of course, nonsense. Sorry.
Best regards, Bauexperte
