Optimal height of finished floor level to street edge

The wording is ,

It is recommended to extend the height of the house by approximately 25 cm; an impairment caused by rainwater must be excluded.

I would follow the recommendation.

I would do the same, better safe than sorry. Weather extremes are generally becoming more intense, at least in the long term.

For what reason? An architect plans it as approved, and a clerk inserts the sentence, and everything before was wrong, In the end, I only have problems keeping the water away from the neighbors,

My water does not run to my neighbors. Only if I were lower could my neighbors' water run to me.

I meant, because you wrote you would like to be on the "mountain"

You are almost like my wife [emoji45]
