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

that a narrow window, 45cm (18 inches) high, looks really great at the corresponding width. You can really enjoy the view of the garden. Fantastic!

Kitchen: the 45cm (18 inches) refers to the rough opening size; the window itself is 28cm (11 inches) high! @One00 should have similar dimensions.
The window ends at 150cm (59 inches) at the top. Try sketching your garden and house layout like I showed above as an example, and position the window with the sill lower—then you can see all the views you’ll get.
