Single-family house, single storey, knee wall, upper floor window

Floor-to-ceiling? Where did I write that? You can place the window band higher than 30 cm, for example 60 cm, window 70 high, lintel... That fits on a 160 cm knee wall. You plan the terrace with gravel covering or a permeable surface. The roof overhang must be under 50 cm. I know that a gallery, meaning an opening in the upper floor slab, reduces the living area, but that would be nonsense, since this area would then be subtracted again from your upstairs living area. But actually every architect should know with which legal means one stays within the number of floors.

I just interpreted it that way! I'm also putting gravel on the terrace! The thing with architects is always a bit tricky! Some say one thing, others another! That's why I asked about the problem again here! On one side I have a dormer, with a knee wall of only 1.60m it gets very tight, probably not feasible. That's why I'm asking about peak wind speeds!

Try to raise a possibly lower knee wall with built-in cabinets. Simply mount sliding doors in front, with shelves and clothes rails behind them, then the lower slope visually disappears without any real loss of quality.

What is a friendly civil servant?

The extremely high knee wall is only important to me because of the windows! That’s why the maximum exploitation! Since you also belong to this area in the second part of your job title, at least as an employee, you surely know this professional field and can definitely interpret it! Will you tell me your LK in Ni?

I don't believe any terrace will be taken off you - but okay. Our house has a footprint of 131 m² and we have 190 m² of living space - so your 121 m² should certainly be enough for 150-160. We have no dormers... with dormers and no tricks on the ground floor, a knee wall height of around ~1.2 m is more realistic - maybe 1.3 m. What kind of "architects" do you have there? Find one who actually charges money; they will surely know exactly and take responsibility for it.

The extremely high knee wall is only important to me because of the windows! That's why we're pushing it to the limit! Since you also belong to this field in the second part of your job title, at least as an employee, you surely know this professional branch and can surely interpret it!

Uh, what does it say about me? I am in the north, the extreme north
