Floor plan new two-story single-family house 200 m²

Honestly? One word doesn’t fit at all in that sentence. And that is "I."
I am not a floor plan analyst. Therefore, I would never presume to design a floor plan myself.
And that is exactly what I recommend to you as well. Not "I," but an architect paid by you should plan.

YOUR architect is paid by you and acts in your interest according to your wishes.

That’s of course true. However, I don’t care about the "how" in the end as long as a floor plan comes out that we like. My suspicion is that my wife and I tend far too much towards micromanagement to just let an architect do his job, no matter how good. Also, the "Christmas holidays" currently lend themselves very well to doing our own drawings and one doesn’t have to wait for appointments. And working at night myself requires significantly less effort for me than organizing childcare again for a baby or sitting in the architect appointment with a potentially stressed baby.

Overall, I also find the design successful, although it is of course absolutely wasteful.

Yes, it could certainly be smaller, but it doesn’t have to be. As long as it fits the budget, we will probably keep it this large.

Especially the cloakroom behind the stairs seems misplaced to me and would be better located near the entrance. Maybe you could swap the guest WC with the cloakroom. Then however you would need access to the WC or study through the living room.

We are still considering that, but the WC at the study was originally the reason for the winding path/the labyrinth. The simple solution would be to center the front door on the north side. Then the WC can stay where it is and you’d still have cloakroom in front of it. But the idea of a main entrance through the carport causes unease for me.

Consider how you want to access the garden in everyday life.

As already written in post #17, ideally I don’t want to access the garden at all. But for the other household members and special occasions, a door in the kitchen would probably be quite good.

Personally, I’m not a fan of covered terraces. The corner will be pretty small and certainly won’t be enough for a large table with many chairs around it. With 2 meters depth, the terrace will probably only offer about 1 meter of shade around noon in the summer.

I have an example right here in front of the window that is similarly sized and we simply like it. Even combined with an external pergola, we find the covered terrace better than without.

Also, personally I don’t see the point of the walk-in closet. I can’t understand the trend at all.

A big advantage is the option to turn on a light and get dressed while the other person is still sleeping, without having to go into the bathroom or disturb the other.

Aside from the cramped situation at the dining area/counter/terrace door with 8 seats in any case, I would completely dismiss this floor plan at first glance, because with the currently planned situation of the house entrance/carport, it is only a matter of time before someone ends up under the car, even if it's just their foot. The driveway directly past the front door can only be seen by me as "unacceptable." In this respect, the floor plan will change anyway. I consider this to be a clear design failure, since one must at least consider a usable area for the front door, which then narrows the driveway to the point of uselessness. We have a similar setup but in front of the house door there is first an elevated platform with a step, where one can move "safely." I would never make a 3.85m wide carport including the house entrance situation.

3.85m wide carport incl. house entrance situation I would never do.

Maybe it was overlooked that only one car is supposed to park there, not two side by side? 4 m width (without outer wall) still leaves enough space for a runway next to the car. In the original plan the entrance was designed differently, but that just wastes even more space. Even if I were starting from scratch, I wouldn't really see any significantly different possibility on the property. We have ruled out an entrance in the middle of the east side (towards the street). We want only one entrance and it should be connected by short paths both on foot and from the carport. So at the north/east corner. I think if you slightly set off the footpath with different paving stones it will surely be good for everyone involved.

Apart from the cramped situation at the dining/counter/terrace door with 8 seats

The drawing shows the table extended. That might happen about 4 days a year. Normally, the table is 65 cm shorter and there are only 6 chairs. We set it up like that once and compared it with other houses and it fits well.

since you have to at least consider a usable area for the front door in front of the house and this then narrows the driveway to the point of being unusable.

I think if you slightly set off the sidewalk with different paving stones, that’s certainly good for everyone involved.

Yes, I’ve also had an eye on that. You just have a platform, preferably a nice platform in front of the front door – that should also have freedom of movement so you don’t tip over on it. You have options there, for example by placing the storage room between the carport and the house. Ultimately, you also try to realize an access to the garden there.

I’m currently sitting in almost the same living room (also with a recessed terrace) and I find that just fine, also regarding the light yield and the view.

Then please explain to me why you have to have a window above the sofa. You can say decoration or reading light. There must be some reason. I would prefer it if there were a closed wall on a sofa wall, which can’t reflect anything against the TV either.

Furthermore, the "Christmas holidays" can currently be used very well for own drawings

as long as a floor plan comes out that we like.

just doing their job

The thing is: the architect’s job is to plan the optimum based on the knowledge of their studies. A layperson simply doesn’t have that knowledge. And so you or you all just cruise around the usual repertoire of the model house and the house-building heroes – but not around the knowledge of individuality. Which then results in currently botched façades and also a non-functional entrance situation, especially when one repairs and straightens rather than considers something new. A layperson just dislikes deleting.

To be honest, I find the kitchen planning the most difficult in terms of spatial imagination and furnishing needs. You can see that in the design with the little kitchen island.

The one who uses the kitchen passionately is the expert. That can also be a kitchen planner.

In this case, I am the intensive user. But all the kitchens I have cooked in so far (and there have been quite a few) have been too small for me, especially regarding workspace and space for kitchen appliances. That's why I still don't know where my optimum actually lies.
