Can one get funding if building without a loan?

We are planning the construction of a new single-family house. Since we have the necessary savings, we do not need any loans. Does that mean that we will not receive any funding at all if we build according to the latest [Kfw] standard (particularly energy-saving)?

In addition to loans, there are also investment grants, for example KfW 430. Yes, there is also money available like that. Just take a look at the list on the KfW website.

(The interest rates are so low, I would still recommend taking out a loan.)

why take out a loan if he has the cash??? in the investment market for safe investments (fixed deposit) he moves around 0.1%
