Floor plan single-family house, ~180m², basement with gable roof

And otherwise, it was initially about the floor plan.

But that would be irrelevant.

Even if you don’t take the 75cm exactly, you can, upon request, remove or add more or less soil (or add another meter on the knee wall )
you build a basement with a garage visible from the front here, so you can go out on the west side, but in the middle go to the back, and in the southeast you then have the landscape level on the ground floor, which, however, cannot be accessed from outside at the front. Basement and ground floor would then be the full stories, attic then with 50 and 75 cm knee wall.
This is now very simplified, but building regulations can be interpreted positively for oneself, although as a layman that is hardly possible.

Not far from here, removals of 1.50m were approved upon request.
I believe that approval would not be a problem.

But that requires argumentation by the architect – as a layman you will probably get a negative decision.

You can’t put a complicated slope under a simple single-family house!

Apart from all the (more than justified) notes regarding the slope, one more thing about the kitchen planning:

If the refrigerator is supposed to stay as it is now, why does it have to go into this built-in niche? As far as I remember, it is supposed to be a stand-alone refrigerator anyway, so it can be seen. I wouldn’t make a built-in niche and limit myself regarding external dimensions (apart from the fact that dirt collects in niches in an unsightly and hard-to-reach way). Either leave the corner open or integrate the refrigerator (then not stand-alone but a built-in model) further back into the (extended) pantry.
Otherwise, I won’t say anything more about the current kitchen solution... I already did.

Garage:
Does it have to have a gable roof? Do you plan to use the attic? If not, I would consider a flat roof. That way, you have no restrictions for the windows in the upper floor.
Think about a roof overhang in the front that shades the pantry window; otherwise, it will heat up in the evening (it’s the west side, right?)

First about the slope: I don’t really think this is such a complicated slope.

The approach is, in my opinion, quite simple: Between the diagonals drawn in red, the height is approximately the same (about 510.25m). Now we simply transfer accordingly from [1] and use this to fill in at [2]. This already creates a 25x25m area (green in the picture) at a relatively even height level of 510.xx.

In the far southeast it remains a bit higher, which isn’t so bad because of privacy protection etc.

If I now look at the driveway from the north, in the northeast there are just 0.75m missing to 510.xx m, and in the northwest from the outermost point 2.10m over 10m length or 1.60m over 7m length.

That shouldn’t normally be a problem, right? As an amateur, I would say I’d make the driveway a ramp that rises comfortably (50cm?) and ends in the garage. For the rest of the incline, I would take, for example, an outside staircase to reach the level of 510.xx m and thus the entrance area.

oh yes, and a basement is also planned.....

Uh ... you have to place the garage on the left side of the plan - right?


Your green area starts about 8 - 9 m away from the street.

And, if you set the green area at around 510 m elevation, then you are missing about 220 cm in height from the top left, northwest. So the garage at ground floor level would have to overcome this height difference from the street, not 75 cm.

Above all, that would mean moving quite a lot of earth masses and making the ground stable again for building.

The planner should properly draw this out for you.

Garage at ground floor level would therefore have to overcome this height difference from the street and not 75 cm.

Somehow speaks in favor of parking with a lift.

As a layman, I would say I'm turning the driveway into a ramp that rises comfortably (50cm?)

50cm is a length measurement. What do you mean, how many percent incline?
