Optimal height of finished floor level to street edge

I would also follow the recommendation if someone logically explained to me where the water that could flow into the house is supposed to come from.

Do you sometimes watch the news???

Yes sure, but then I have to increase by one meter

Besides, I meant the water in my circumstances. The street is 10 m away from the front door, the door is 18 cm higher than the street, the lower terrain in front of the house would have to be completely flooded, even if that happens, it flows back to the other side of the street because the street has a slope of about 20 cm, on the other side the properties are even lower,

Well then, it's okay as planned? Others can recommend a lot; in the end, you live in Du and if you look at the surroundings with some common sense and think it’s okay, then do it the way you want. I also build the way I want and don't let others interfere.

I only think about the future. At first, my property was also almost at street level. I was a child then, and today I lie 60 cm lower than my neighbor. All the other properties have been filled up. The street has also been renewed and as a result higher.
