Floor plan design single-family house in L-shape

So now I have let some time pass (unfortunately we still don’t have an appointment with the architect, I have already tried to arrange one).

The whole thing with the upper floor and recessing was a bit exhausting to plan, so I have now tried a version with a living basement and only one floor. A big question mark is of course still whether the garage will work the way we want it to, or how much the fun will cost us if we do it like a "basement garage". In the end, the garage will cost us a lot no matter how we do it. Because if it is upstairs, it will probably still have to be basemented (due to the slope) or built up with a retaining wall then. I think both options will be quite expensive.

The current design actually already pleases both of us very much. What do you think about it?
The two windows in the living room will only be small basement windows here; by that place, we should already be somewhat above ground level to be able to make small upper windows there.

We might still want to make the garage/workshop smaller because we come to quite a few square meters overall. I would be interested to know whether this design would be more expensive than the previous ones with 2 floors + basement. Previously it was about: 100 sqm basement + 100 sqm ground floor + 50 sqm upper floor and now 150 sqm living basement + 90 sqm ground floor, so roughly the same in square meters. Are there still price differences? Is building "up" more expensive than building "wide"?

Please be so kind and draw it in such a way that one can see how the plan lies on the property. It certainly looks like that impossible driveway to the property is planned again. And now it should then become a staircase to the house entrance or something similar. You have to plan the house WITH the terrain.

Is building "high" more expensive than building "wide"?

Definitely, the building must be adapted to the planning imagination of the client rather than letting the architects implement "alone" whatever one wants. Architects also understand verbally formulated assignments; you don’t have to draw everything out for them.

There should be a kind of "pharmacy-only" regulation for plots: slope only with an architect ;-)

Slope properties are simply difficult. I often have trouble imagining them as well. And I then try to force my house designer to depict as realistic a terrain as possible, which is why site plans with elevation details, etc., are always necessary.

Slope properties are simply difficult.

Partly indeed, yes. Sometimes the greater part of the difficulty, however, lies (initially) in the meeting of a slope property and a flat-property mindset builder. Example garage: if it stands next to it, you have the freedom to place it neither in the basement nor in the ground floor but anywhere in between, as it fits the driveway. And suddenly it hasn't even cost any brains to make the cubature appear "dynamic."

The idea of a garage accessed from the side seems absurd to me here. I would take one of the roads, here the upper one. And would orient the gate towards it.

, you can no longer link images, but posts still work ;). The site plan in ... which street do you mean by "above"? I only see the street to the west and would rather approach from the bottom left.
