Newly built semi-detached house 155 sqm - orientation & floor plan accordingly

If the is really like that, then the house should be at the lower building limit. The entrance should be at the front or on the side.

Do you know the neighbors?

Do you know the neighbors?

Yes!

What do you mean, you would leave the location as is? So the rear building boundary with the current plan?

Yes, I would leave it like that. Explanation follows with a little picture.

Here’s another question, why is the dining/kitchen area in the south and the living area in the north? Or was that just done quickly without paying attention?

Because in winter (from O to O) you catch the sun from the south and the light is needed and good during the day. The dark season is a long season.
And I can’t imagine that you fight on the sofa every day in winter like some TEs imagine here, who do nothing but couch in an apartment.
That’s also why I asked earlier.

It is important to us that it is connected to some extent.

Well, and since I have the day off today and it’s actually too warm for me in the sun, and I have paced the terrace/kitchen area many times (my husband too... to get drinks and ice), here is my suggestion:
Basically I am known for changing floor plans. In this case, I almost leave it. Partly because I like the house visually very much. It’s not a cube bunker without charm, and compromises always have to be made somehow. Whether you move the bay window or leave it as is... Whether you get a bit more out of what I consider a way too small and therefore uncomfortable staircase or whether you change something about the window situation, you can see. Personally, I would probably move the entrance a bit more forward. But I find the entrance situation with you quite exciting and generous. It’s not a fiddle like elsewhere. It’s comfortable without frills. Great. And the width of the house is also nice. By the way, the views don’t match the floor plans.

Anyway: here is my terrace and living area proposal. And I bet: if you implement the terrace in the north like this, then colorful lanterns will dangle there, bamboo will be planted, lights in between, and it will be the best place to lounge with your aperol in the summer evenings. A la Pinterest. And it will probably also be the favorite place during the day. Nevertheless, I would plan the house exactly like this towards the back because the north terrace benefits from the reduced size of the garden.
Long story short...

I unfortunately still haven't understood how to quote only individual sentences, so I always have to quote everything.

Move the cursor to the beginning of the passage you want to quote, hold the mouse button down until the "end," and then click on the "Quote" option. You can do this with several passages one after the other.

but we would actually align the upper floor (OG) to the ground floor (EG), since the ground floor is much more important to us. If it then turns out that you can't fit 3 rooms and a bathroom in the upper floor (OG), of course, it looks different.

That has nothing to do with "importance," but with weght. First, you create and qualify the room program, then you proceed to the, let's say, fine arrangement. This either starts in the more differentiated upper floor (OG) or you regret the "wrong" planning (bottom up) with structural-engineering struggles. The best positioning of load-bearing walls is on top of each other.

If the is really like that, then the house should be placed on the lower building boundary. The entrance should be to the front or to the side.

Do you know the neighbors?

Can you briefly explain why? Because nothing would then ever be allowed to be built there?

Well, and because I have the day off today and it is actually too warm for me in the sun, and I have already walked back and forth along the terrace/kitchen corridor dozens of times (my husband too... to get drinks and ice), here is my suggestion:
Basically, I am known for altering floor plans. In this case, I almost don’t. On the one hand, because I really like the look of the house. It’s not a cube bunker without charm, and compromises always have to be made somehow. Whether you move the bay window now or leave it as is… Whether you get a bit more out of the staircase, which in my eyes is way too small and therefore uncomfortable, or whether you change something about the window situation, you can consider. Personally, I would probably move the entrance a bit more forward. But I find the entrance situation with you quite exciting and generous. It’s not a botched job like elsewhere. It is comfortable without frills. Great. And the width of the house is nice too. By the way, the elevations don’t match the floor plans.

First of all, thank you very much for your efforts! You hit quite a few points well.

Why is the staircase way too small for you? Also in relation to the topic of enlarging the living space?
Why would you move the entrance forward and what would it look like then? If you find the entrance generous, do you mean it could also be smaller?
You mentioned that the elevations don’t match the floor plans? We have not noticed that yet.

Anyway: here is my terrace and living space suggestion. And I bet: if you implement the terrace to the north like this, then colorful lanterns will dangle there, bamboo will be planted, lights in between, and it will be one of the best places to lounge with your Aperol in the summer evenings. A la Pinterest. And it will probably also become the favorite spot during the day. Nevertheless, I would plan the house exactly like that to the back, because the north terrace benefits from the reduced size of the garden.
Long story short…

Did you also take the neighboring houses into account in your decision? I mean that to the south first there are 2-3 meters of a neighboring house on that side and that the neighbors to the north will first see our house?
Why does the north terrace benefit from the smaller size of the garden?
And you would put the kitchen in the south or swap it with the living room, since you’re only in the living room in the evenings to watch TV anyway, right?

Would you have any ideas on how to design it so that there is also a “living space” facing north? Since the door to the north terrace just goes through the hallway. I kind of find that “uncozy,” but I absolutely can’t think of any other solution on how to do it better...

Thank you for your help!

Can you briefly justify that?

Because I prefer to have my place of residence in a quiet area. Hence the inquiry whether you know the neighbors (especially to the north). Maybe they have a party every day.

Have you planned a patio roof in the south?

Because nothing is allowed to be built there?

Why not? You can always build up to the building limit.
