Placement of single-family house and large garage on plot with sewage canal

I'm also stuck, because the most obvious thing, if the large garage = double garage, is this, even if there would be no sewage canal (of course you could still move the house and/or garage further towards the street, i.e. to the east)

Thank you for your consideration, we have also already thought about that. But we actually "fear" that there will be very little space left for the terrace and that we will not have a south-facing garden at all. And the garage would take away many possibilities for windows on the north side. And we don't really want to design the house narrower...
Are these concerns unfounded?

I would make the access from the south side, then right at the eastern boundary. The slope does not look too bad to me. Or the access directly from the east. The garage definitely in the northeast corner of the property.

A garage in the east would lead to a driveway from the south, which is not quite so easy due to the sloping street. (See pictures)

hm... can you insert a Google Maps screenshot? It's not exactly clear from which corner the photos were taken.
I would orient my terrace where I a) have sun and b) can somewhat shield myself from the surroundings, if necessary.
If there are taller houses somewhere or on one side a nice single-family house garden, then I would include it in the planning.
You now have a street/path around the property, right?

And we actually don’t want to make the house narrower...

Why not? A house is planned according to the plot, so all options are still open!

Are these concerns unfounded?

I think so, yes.

Look (the house is approximately 10 x 12 placeholder):
Approach from the west:

Approach from the south (or also from the east)

With every placement, you create a nice south garden, possibly also west... however, of course, the floor plan can have an impact.

P.s. I have now made the garage 7 meters wide. And I just noticed you want it 7 meters deep? Then in some variants you even have an extra meter of south garden, if needed...

hm... can you insert a screenshot from GoogleMaps? It's not really clear from which corner the photos were taken.

Of course, I can do that.

And first of all, thank you for your detailed response. I will take a closer look at your suggestions this evening and get back to you then.

My reply took a little longer than I thought. In the meantime, we had another conversation with our real estate agent and the associated architect. We have now worked out possibilities with the ideas from this post. We will definitely make the driveway from the west. I tried to sketch the 3 ideas. The garden should still be in the south and west (and thus "right outside the front door"). Opinions welcome! Variant 1: Garage on the north boundary and covered walkway to the front door over a corridor. Access from the north side Variant 1A: Similar to Variant 1 but without a cover and house set further back. Variant 2: Detached house with a gap to the north side of the property (in our view the placement with the "most garden")

- Access is actually planned from the street on the west, but could also be driven from the south side; however, I think this is not optimal, as there is a slight incline here (see pictures)

So definitely not from the east, as suggested?

Or the access directly from the east. The garage definitely in the northeast corner of the property.

Option 2: Detached house with a gap to the north side of the property (From our point of view, the placement with the "most garden")

Option 2 with a (north)east garage would create the largest (west) garden, right?
