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!

At the final inspection, there was a very simple temporary railing in place.
A temporary railing is quite different from a planned one that hasn’t been built yet. 😉 For our planned roof terrace, we will also have a temporary fall protection, since the terrace itself doesn’t yet have any guardrails. However, the door leading to the terrace is already installed. So, a baby gate will be clamped into the door frame. That will be sufficient.

Honestly? How crazy is it to build a patio door that leads to nowhere? If the window isn’t fixed, it will always open somehow. And then having a full door opening into the interior? Better to have the lower part fixed and the upper part operable. That’s not such a big issue.

The main problem is that a closed window alone is not sufficient. The intended use case for the safety check is always: an intoxicated guest standing by the window. They can probably still open it (if it can be opened) – and thus fall out. Therefore, some form of mechanical protection against falling out must be in place.

If you lack imagination, you might think that way. For us, the deep window proves very effective—both visually and for ventilation. A sill height of about 30cm (12 inches) fits the room perfectly. Installing a fall protection would spoil the nice view.

It almost always does, but for that reason, it can hardly ever be omitted. 😉

I have plenty of imagination 😉 . Your window is also just "deep." In our previous house, we had a 40cm (16 inches) parapet height next to the sofa on the ground floor for a view into the forest. But that is somewhat different from a balcony door on the upper floor opening onto nothing.

In the original poster’s case, there are also several (or all?) windows on the upper floor.
