Window sill height 130 in the bedroom / study?

Yes, exactly! In my opinion, you now have too few of them. I wouldn’t control that through window position and size, but rather through privacy screens inside and especially outside. Why? My wife didn’t want that either, and for us it coincidentally worked quite well with our other wishes, which is why we are fairly symmetrical. But I didn’t understand that and I would have been completely indifferent about it. At some point, my wife wouldn’t let me ask further, for the sake of domestic peace. But with you, I dare! Why is the symmetrical or even identical arrangement of the windows from the outside so important when you yourself are inside?

There are also few examples of absolute symmetry in very good architecture. I am not a fan of houses whose façade completely lacks harmony because they were planned only from the inside out. But I would make the sill height as it fits the room. Not every room MUST be flooded with light.

@11ant By projections you mean the ones at the corner windows, right?

No, I mean the projections and recesses on the entire building structure, this jumble of indentations and projections of numerous sub-cuboids.

so I tried a little bit more...

Well, at least you’ve already taken off the smokey eyes.

As @11ant already suggests, one can recognize a number of costly details. No problem if the budget allows it, there is no law requiring cost-efficient building.

I only mentioned the costs to illustrate them. I find the cost (in)efficiency less regrettable than the fact that these lavish extra expenses are also aesthetically inefficient. Lots of sculpting on the overall building structure, and all completely “for nothing” (because the OP doesn’t even see the projections and recesses and asks me if I might mean the corner window mullions).

I would only do windows with a high sill height where there is a reasonable justification. For example, we have several windows at 1.25m: one behind a kitchen counter because we use the windowsill there as additional shelf space, one (we live on a hillside) on the hillside side to specifically direct the view upwards to the summit cross, and one in the entrance hall because the staircase runs along the wall and I didn’t want the sill too close to the stairs.

Sills don’t even have to be raised completely: kitchen herb pots can also stand on the fixed-glass lower parts of windows that aren’t raised higher...

We somehow don’t want a puzzle of windows on the house.

That is commendable, but it would be less disturbing than a puzzle of projections and recesses.

Why is the symmetrical or even identical arrangement of windows from the outside so important when you yourself are sitting inside?

Precisely a window distribution symmetrical from the inside for the individual wall would reliably result in breaking a rigid external symmetry. That doesn’t guarantee that alternating precedence for the inner and then the outer symmetry would be the golden mean – but it would be worth a try.

OK, I admit it – that was too much text :rolleyes:

Short version: I didn’t write "do it like in this picture," but rather advocated thinking completely freely when planning the interior. And if you manage that (and I’m afraid you’re somehow stuck right now), then maybe such a puzzle as an intermediate step can result. After that applies:

one tames the whole thing e.g. through repeating proportions or formats (which can alternate standing or lying), alignments between ground floor/upper floor, etc. But it is important that when planning the interior you think completely freely. Whether, and to what extent, you normalize that again for the exterior view is a subsequent step.

There are functional aspects in your post beyond the exterior view – that’s what this is about:

... don’t particularly like the floor-to-ceiling windows on the upper floor ... Of course it’s important to me that I have enough light ... occasionally a view from above ... so that not everyone can look into the house ... We somehow don’t want a puzzle of windows on the house.

Between floor-to-ceiling and 130 cm there are still 129 other centimeters. We, for example, mostly have 65 cm. With that you can look out, but others can’t look in. We didn’t want a puzzle either, so we standardized on 95 cm and 165 cm. So either 95x165 (portrait or landscape) or 95x95 or 165x165, all windows at a uniform top edge (225 cm).

You currently don’t have enough light, and regarding the view from above my wife at least has to stand on tiptoes to see out of 125 cm windows.

My recommendation is to initially completely detach yourself from the outside when planning and think exclusively functionally from the inside. Creative chaos is definitely welcome as an intermediate step, because the subsequent sorting and standardizing is much easier than the current approach. Just give it a try... you can always throw it away :)

We personally are not particularly fond of the floor-to-ceiling windows on the upper floor; I could never imagine having something like that in the bathroom.

You don’t have to. But just because you absolutely want to have window bands in the bathroom (which aren’t even really window bands, but just higher sills) doesn’t mean you have to do it the same way in all rooms. As I understood , he was just trying to convey the thing about the windows, their size and positioning to you. Ultimately, they are not only intended to structure the exterior, but to illuminate a room in a house that is lived in. YOU don’t just look at the house from the outside!

that everyone can peek into my house

Are you building on a marketplace? Or are you so important that PEOPLE stop in front of your windows to peek in? Yes, privacy and protecting private matters from view! But always keep things in perspective.

We somehow don’t want such a puzzle of windows on the house.

Nobody is saying that! Although it kind of looks like that: absolutely the window band, and if not in the bathroom, then at least kindly above the bed. When you then live in the house, you curse it because in summer you have to darken it extensively in order to be able to sleep because of overheating and light. Then small windows are collected and below some big ones – it’s almost like sorting puzzle pieces ;) As already said: in the south, some window surfaces are very sensible, especially if living rooms are to be illuminated there. But the crux here is that the rooms were not oriented in a way that would be more sensible.

We somehow don’t want to have such a puzzle of windows on the house.

When is something a puzzle? There is always something in between that wouldn’t deserve such a negative label. It has been said many times that you would do well to plan the windows from the inside, but you defend yourself against it. You don’t have to, apparently external symmetry is so important to you that you should just do it that way.

Parapets do not even have to slide up completely: kitchen herb pots can also stand on fixed-glass lower sections of windows that are not raised higher ...

They can, indeed. However, we oriented ourselves to the two neighboring 125cm windows to avoid a puzzle effect (by the way, I find countertops running into the window reveal excessive and impractical). And in the present floor plan, the problem is solved by having no window in the kitchen at all. Tough times for kitchen herbs ;)
