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!

According to building regulations, this can be achieved by installing a restrictor that prevents the window from being opened fully. It can then only be tilted. This is common in some hotels.

However, you need to ensure that escape routes are not blocked by this.

Why not have a French balcony on glass? For example, we have one. It is more or less invisible. Or even simpler, since you mentioned removing the handles, just fixed glazing.

The idea of the barrier is brilliant!
The second emergency exit would be possible because there is still a window left on the other side that can be fully opened.

I find French balconies to be quite impractical. They are relatively expensive considering the negative impact on the appearance and slightly reduce the view.
I am more willing to accept the forced additional investment if I can at least expect better burglary and sound protection from the expensive panes.

Is there anyone here who can actually look back on having received their official building permit / planning permission under the same conditions?
I’m afraid of complications and feel I would have achieved less if I were ultimately forced to install a parapet after all. Especially without scaffolding and proper support. 🙄
