If a so-called "new" plan resembles its predecessors so much that you can only see differences with a magnifying glass, apparently most of the comments have not been taken into account – how many of those were from me is irrelevant. Nevertheless, a statement implying that no concrete comments have yet come from me is quite cheeky.
I have not claimed that no concrete comments have come from you. I was only referring to this comment.
Well, no light from the west and east in the living room – only 2 south terrace doors – the sofa is in front of one, the table in front of the other.
The window width in the children's rooms is only 1.50m. The frames take away some of that. That leaves more or less a narrow strip on the west side. Although it is nicer when they are floor-to-ceiling, the amount of light changes only slightly because of that. Upstairs hallway completely dark – not even a double casement window. Bedroom only a narrow door on the east. If you only slept there, okay. But when the wife puts on a dress, she already no longer knows if the color of the shoes really matches. The nicest room upstairs will probably be the office.
They make wide windows and use almost the entire gable width. If the rooms are bigger (like here), double casement windows are installed. I find your fear of wear or thermal bridges of the same strange. I don’t have double casement windows because the house is two stories. In the holiday home we have several; I can confirm zero problems there, but I’m only there 2 weeks a year. Maybe someone else can say something about it. In my opinion, the concerns are quite unfounded, or the wear is no different than with other windows.
I find the statement "The whole house will be quite dark overall." simply wrong. I also wish for clear suggestions for improvement, like from you.
Regarding the criticisms to consider.
1. With this floor plan, I have to decide between a shed or windows in the west. I choose the shed. Also because there is an apartment block ("Plattenblock") in the west. I cannot place the garage on the east side because of the street narrowing.
2. Regarding the gable width windows: I cannot give the gable windows more than 2m. So you mean that 2x1m wide windows on the gables bring more than 1.5 x 2m wide windows that go to the floor? Purely mathematically, I have more window area with the latter. Therefore, I cannot understand your argument.
3. We only sleep in the bedroom. Installing a roof window there would probably cause noise that you don't want while sleeping.
I agree with you about the hallway upstairs. Maybe recess the bathroom/storage room and create a narrow strip beside the stairs and install a double casement window there? Then you access the double casement window and have light in the hallway.
