ᐅ Floor-to-ceiling windows on the upper floor without a parapet or knee wall

Hello everyone!

I have been following the forum for a while, but now I have some current questions that I haven’t found answers to yet, so I have become a more active member.
I would like to avoid using guard rails on the lower edge of floor-to-ceiling windows upstairs to eliminate the risk of falling from the window sill.
Therefore, I plan to implement the following alternative measures:

1. Use safety glass corresponding to category A *

2. Lockable with a key, with the key stored elsewhere

3. Visible indicators on the window such as blinds or frosted glass stickers

4. Restrict access by placing furniture or plants in front of the windows

Has anyone here already received official building approval for something like this?

I would also be willing to remove the window handles if it came down to it.

For those who haven’t figured it out yet—I’m not a fan of French balconies, transoms, or divided windows.

Perhaps someone has done something similar with windows that are basically fixed?

Thank you for sharing your experience!

With the tilt lock, you can only tilt the window when it is locked, and for example, for cleaning, you can open the window using a key at the bottom frame.

Thank you!
By the way, I’m also impressed by this wonderful view and I envy you!

But do I understand correctly* or is it just my wishful thinking?* that you managed to find a solution WITHOUT a railing but WITH a key? Because I wouldn’t mind exactly WHERE the key is used, whether at the window handle or at the bottom edge of the window like in the hallway photo from Nordanney.

I don’t want to spread half-knowledge or (pun intended) overextend myself, but I think it doesn’t matter where and how you lock the window. Other factors are more important here: the state or region, the number of residential units—that is, the building classification—laminated safety glass, and certainly the interpretation by the building authority. For questions like this, I would ALWAYS contact them directly.

This was even approved by the German building authority (Baden-Württemberg).
Ah, Baden-Württemberg – from the view, I would have expected Switzerland. Although, in a way, it’s kind of “both” (BÜS) :-)

Try searching for "hausbauhelden ravenna Helma" on YouTube. Then go to minute 21. Is that how you want it?

I can't imagine that this is such an unusual request or that there are any building regulation issues if they even install it like that in the show home.

Yes, that would be fine for us. Thanks for the link.

If I were a building inspector and open to a homeowner’s idea, I would always prefer, in cases where some discretion is involved, to not receive a very detailed explanation at the critical moment or to not look too closely, rather than explicitly issuing a written permission in response to a citizen's formal request that I would then have to be accountable for over many years. I have nothing to gain from it.

The examples in this thread show that even among citizens/homeowners, there are widely different interpretations of the same regulation.

It would be interesting now, in addition to the few EXPERIENCE reports of successful implementation of windows without a parapet, to receive at least one where the building authority did NOT cooperate—where there were issues during the acceptance inspection.

In the commercial sector, we have already had to retrofit windows. However, due to occupational safety regulations, inspections are naturally more thorough.
