ᐅ Window Planning for the Attic – Larger Gable Window or Roof Window

Hello everyone,
we are in the final stages of planning our semi-detached house and have designed a fairly large window with a slope in the attic.
The standard window planned here is a gable window measuring 1.54 x 1.14 meters (5 ft 1 in x 3 ft 9 in).
This seemed a bit small for the room, so we now have two options:
Option 1: A roof window measuring 0.94 x 1.18 meters (3 ft 1 in x 3 ft 10 in) (Velux GTU) for 1575 EUR
or
Option 2: Just enlarge the gable window by 40 cm (16 inches) for 803 EUR
The glazing of the frame would of course be the full 40 cm (16 inches) wider, but the visible area at the upper part would only be 22 cm (9 inches) wider, due to what remains limited by the frame and other elements.
What would you do?
The room will be used as a bedroom/children’s room, and I’m not a big fan of double casement windows. Also, photovoltaic panels are planned for this side of the roof, so the double casement window would take up space needed for that.
What would you do in our situation? Is it worth enlarging the gable window, or would you choose the double casement window?
Thanks a lot for your input!
Best regards

We are building to KfW55 standard and using a ventilation system. But the tip about using a single-leaf window is really good, Who are you responding to? From 1 meter (39 inches) width, people usually go for double-leaf.

But with double-leaf, don’t I lose even more window area because the sash takes up frame space? That’s actually the reason why the window was proposed like this. Let’s ask the question differently: what does the south facade look like otherwise?
A double casement window can now be very well shaded, optionally with automated systems. A standard-sized double casement window including motorized external shading costs around 3,000 at the time of new construction, but retrofitting is typically between 4,500 and 5,000. If the reveals can be angled, it lets in incredibly beautiful light. Only skip this if finances are tight; otherwise, definitely include it.
And what is really loud anyway? The sound of rain hitting the glass can be calming (similar to the sound of ocean waves); you just have to associate the noise with something positive (I do this with the baby crying in the apartment below me—I now always feel cheerful when the baby cries 😀).

Thank you all for the lively discussion!
What about the aspect that the window reduces the solar panel area? I can’t quite assess that yet, since we don’t have any quotes at the moment and don’t know how the area will be utilized. However, we would like to be able to produce a full 10 kW.
