Height of top edge of base plate / street level

Hello,

we are planning a single-family house on a slab foundation without a basement.

How high should the top edge of the finished floor be above the street level at the boundaries?

Since our property has a slope, we do not want to raise it unnecessarily high to avoid a one-sided fill.

Is there a guideline for that?

Is there nothing in the development plan? For example, "According to § 9 (2) of the Building Code, the height of the top edge of the finished ground floor floor – measured in the middle of the building – must be at least 10 cm and at most 30 cm above the top edge of the finished access road."

How much additional workspace was excavated around the floor slab at your site?

1m more completely all around

Is 1m sufficient? Or is it advisable to excavate even larger?

I am surprised that you, as a "mason," are asking these questions
