Enough daylight in the children's rooms?

Hello everyone,

we are about to start our construction project. We are satisfied with the floor plan of our gable roof house, but we have been reconsidering whether the window size in the two children's rooms (upper floor) is sufficient. Therefore, I would like to get your opinions.

In the attachment, you can see the floor plans and all house views. The specification for all 4 upper floor windows was "floor-to-ceiling with a fixed lower part" and "single-leaf." Currently, the bathroom on the north side and the guest room on the south side have a roof window. Somehow, we feel that the two children's rooms could use more light so that the rooms do not appear too dark. Widening the windows does not fit from the outside view, at least on the east side.

Now the question: Would adding another roof window in each children's room make sense, or is there something speaking against it? The house would then have 4 roof windows, and that seems quite a lot to me. Or is the window width and height perhaps sufficient after all?

I would be very grateful for your opinions.

"Enough" is it. But I would simply widen the windows to 1.76 m or at least 1.5 m.

Hmm, well, I would tend to go for roof windows...

It's sufficient... nevertheless, in my opinion, it's simply better with roof windows...

How high is your knee wall and what is the roof pitch? And why shouldn't a wider window fit? Ours are 1.26 meters wide (about 2m high) and I think they shouldn't have been any smaller (room size 16m2). One reason that, in my opinion, speaks against skylights is the southern location. In summer, they would be shaded all the time anyway.

"Sufficient" is it. But I would simply widen the windows to 1.76 m or at least 1.5 m.

On the west side, that doesn't work because the chimney in the bedroom limits the space for an additional window width. On the east side, it wouldn't fit because then the children's room window would no longer visually fit between the two small windows on the ground floor.

We would then have 3 roof windows on the southern window side. Would there still be space for solar thermal panels on the roof? Are there any other disadvantages when "sacrificing" roof tiles with insulation for a roof window?

Ok, those who can read are clearly at an advantage. Knee wall height and roof pitch found :-)
