Windows & window size: what to choose? Double-leaf windows?

it is completely fine. Brainstorming, different aspects, opinions, criticism, tips, etc. are valuable things needed to find a solution.

Hello everyone, I also think 01 is the best solution so far. Today I combined the ideas a bit, so the windows of Child 2, Work and Bathroom are 151 cm and double-leaf, the toilet window has the same sill height as the bathroom and instead of 63.5 I made it 76 (about half the size of the bathroom window) and I personally don’t think that’s bad at all. What do you think?

I would not make the window (Gäste-WC) next to the front door so small and square, but simply at the railing height of the other large windows. After all, such a window is also supposed to serve the purpose of making the room bright. Our Gäste-WC window is 1m x 1.38m and it is nice and bright.

Best regards

Yes, you can also bring uniformity into it that way, and I like the result too. I would then do the bathroom window with a mullion and those in the living areas with a French casement, so that they can be opened in full width (which would also be relevant if they need to be escape routes).

, you are right, it would be even more harmonious if the distance between the bathroom window and the front door were greater. But that probably isn’t possible because the interior layout doesn’t allow it. However, I have to discuss that with BU on Monday.
, that is also a good idea.

You could still win an architecture prize with the next house, for living with the family this one is now beautiful enough. By the way, the rhythm should roughly match up to the middle of the side section.
So leave it as it is.
