100 square meters basement for 150,000 euros?

So we also wanted to have a basement.. about 70sqm.. with KFW 55 it would have cost 100,000 extra... we then decided against it because we didn’t want to spend 100,000 on "storage space"... however Schleswig Holstein...

The price indication, however, does not include the additional civil engineering costs (must the excavation material be disposed of?) as well as painting and flooring work

Depending on your circumstances, you can therefore quite possibly achieve or exceed the specified value...
