The thread is now almost a year old, so thanks for revisiting it! Even without this preparation, we basically find the external stairway to the upper floor sensible (among other things, more privacy). Unfortunately, the privacy of the guest WC has so far been neglected. At least for the missing space (sleeping/hobby), a later separation of the living room from the open-plan area would be conceivable. The WC, however, will probably have to remain that small. Placement of the kitchen east vs. west was a long-standing topic. For various reasons, the decision has now been made as it is (including proximity to the utility room). We chose standard windows in the living room since the sofa will probably stand there anyway. On the upper floor (bathroom and children's rooms), there are floor-to-ceiling windows with fixed glazing at the bottom. Good point. We want to move the south wall in the bathroom about 15cm, as suggested by ; this will probably alleviate the problem. Yes, with the current placement we also allow the terrace a bit of privacy from the street. We also weighed both options for a long time.

The architect also encouraged us to use floor-to-ceiling windows. Due to the very wide cladding at the ceiling (because of the roller shutter / venetian blind box), our windows still have a kind of "lintel."

There must surely be experience here with floor-to-ceiling windows and "invisible" venetian blind boxes. With our suspended ceiling, it should actually be easier to implement, right?

Is it possible to prefabricate a concrete lintel as thick as the suspended ceiling and put the insulation on the outside of the box?

If a suspended ceiling is planned, it should actually be possible according to the execution plan to make the windows appear flush with the ceiling. You definitely do not want it the way outlined in the alternative – classic thermal bridge. There is something similar for ETICS facades, google ROKA-SHADOW® 2 WDVS-SA.

Thanks , I’ve now recognized the error. The insulation on the outside of course does nothing if cold air comes into the concrete ceiling from below through the open roller shutter box.

But I’m still confused about how the windows are supposed to appear floor-to-ceiling in the planned version. What bothers me here is the ~15cm frame extension (marked in red in the picture). Although I have a floor-to-ceiling window opening, I do not have a floor-to-ceiling window. With accordingly less light incidence. I cannot see the advantage over a non-floor-to-ceiling window (classic with lintel).

I can only achieve a "real" floor-to-ceiling window by pushing the roller shutter box further up. And accordingly I have to recess the concrete ceiling to also accommodate the insulation between ceiling and box. Or we use an outwardly visually unconventional box mounted on the facade. Or am I missing something?

The suspended ceiling is lowered about 10cm as shown in the section.

Thanks again for your suggestion.
We are a bit reluctant to put in an extra hallway with a door. We are currently thinking more in terms of a "light separation" with a short wall without a door to soften the line of sight. But we are still not completely happy with the whole thing:



We have also adjusted the layout of the WC once again. We like the shower on the exterior wall best because that gives a bit more space in the entrance area of the WC/shower.

Advantage:

    [*]No dark mini hallway
    [*]WC visually somewhat separated (toilet no longer visible from the dining table)


Disadvantage:

    [*]No improvement in separating odors and noises


Are there any other ideas/opinions?
We had also considered having the WC door open outward into the living area. That would make the WC somewhat more private from view and give us a bit more space inside.

Well, if you are working with lightweight construction in the upper floor, I have this one:



However, if I were you, I would work with a slightly higher knee wall. So far, I haven’t understood why you are placing the slopes so low (Where exactly are they?). 1.30m is common. That is a typical dimension at which the back wall of most beds fits comfortably against the wall under the slope.
