ᐅ Are there special regulations for porthole windows? Single-family house with 1.5 stories.

Dear community,
My family and I are considering building a new single-family house. According to the current plan, the house would have one and a half floors. In the bedroom on the upper floor, the knee wall height is about 1.70m (5 feet 7 inches). Please don’t laugh, but I’m someone who likes to be able to look outside on all four sides of the house. Unfortunately, with a knee wall of 1.70m (5 feet 7 inches), a roof window wouldn’t make that possible. Now I’m looking for a solution.
- Dormer -
To be honest, it’s too expensive for me.
- Roof window with fixed glazing -
That’s an option, but with shutters and so on, it’s also quite costly.
- Window slit -
According to the architect, the glass pane for the window slit would only be about 15cm (6 inches) high. That seems very small. Not really worth it, right?
Would a porthole window be an idea? Are there any special regulations for that? Could a small porthole window of about 60–70cm (24–28 inches) be installed with a knee wall height of 1.70m (5 feet 7 inches), or is that too tight? How much would a round window like that typically cost?
I’m grateful for any advice. Maybe you have other suggestions to solve my window problem?
Best regards,
Marple

I somehow find porthole windows a bit 90s, but the 90s are actually making a comeback right now.
We have both a "corner window" and strip windows on the eaves side, knee wall 1.89m (6 ft 2 in) with a 20° roof pitch.
We really like both, even though you can’t really see out of the strip windows while standing. But they do bring in a lot of light.

A recessed upper floor cannot be denied to you.

Two full stories would definitely be my preference, but unfortunately, the building regulations in our residential area do not allow that.

Thank you for all the tips and advice! I’ll have to look up the stepped roof story (setback story) right away. Maybe that’s our solution?!
A folding balcony isn’t necessary for us since we have a knee wall of 1.70m (5 feet 7 inches). In my opinion, a folding balcony makes most sense directly under the roof.
I like Elina’s option. It’s the combination of fixed glazing and roof windows. However, our builder said that with a roller shutter, it’s quite expensive (over 3000 EUR).
@One00: What do your light strips look like? At what height did you install them and how tall are the openings? Can these light strips be opened? Or can they be darkened? Thanks!
@ypg: Do you have grilles in front of the deep windows? Or are they fixed glazing? Our architect said there must be a 30cm (12 inches) roller shutter box above the window and about a 20cm (8 inches) concrete lintel above that. Also, the window cannot be installed lower than 90cm (35 inches) above the finished floor level; otherwise, it can’t be opened or must have special fall protection. That put me off.
Thanks and best regards,
