Is the garage driveway possible and somewhat practical for everyday use?

Show the entire structure…

Just like driver55 says, show everything or have the garage downstairs, then you still have a 2-meter distance to the house or even add a carport. Etc..

If the wall on the right is movable.. why not shift the entire garage as far to the right as possible? Then the terrace on the garage will be even bigger and you will have a covered passage.

Moving it further to the right is (of course) not possible, otherwise we would have planned it that way...

Garage moved slightly backward and a bit further to the right, I think that's the only option. Driving in that way is possible then (driving straight in would be nicer, but just not feasible given the environment/boundaries/wall).

I think that is the only option.

It is bad when you do not think through the options further yourself.

There are no "alternatives," except turning the garage 90° and placing it "downwards" against the wall

For me, the location of the garage according to the plan downwards would not be an alternative, but the first choice.

then it is in front of the front door and

You can change all that… usually the entrance area with wardrobe and hallway can simply be rotated… I don’t understand why you reject that for yourself.

Our garage is also, like in your alternative, right in front of the house and we think that's great. Short distance from the car to the house and no visibility when the front door is open. We don't see any problem. Your currently planned garage, on the other hand, would be too stressful for me to drive into and therefore only usable for junk and bicycles.
