This is the answer to the question What kind of windows have you chosen for your homes?
Revision 1
First of all (ideally this is done by an architect, but often construction is done without one), I would determine the lighting requirements for individual rooms. Depending on the size of the room there are (minimum) window areas, which can now be expanded as desired. Children's rooms need to be lighter, but for the guest bathroom it's somehow not as important.
In my opinion, especially beautiful corner windows or rooms with windows on two adjacent walls. This process needs to be coordinated again and again with the views of the house (which are more or less determined by the floor plan).
Whether there will now be one or two casements depends primarily on the width of the window. Very wide windows result in heavy sashes that also protrude far into the room when the window is open. It makes sense that you would have a lot of double casement windows (because you identified large window areas for lots of light in the first step).
With or without a center window (no means double sided window) is a matter of taste. Without a post, the possible free opening will be larger, but the second sash cannot be tilted and can only be opened when the first one is open (so you need to decide which sash should be first; turn-and-tilt). In the case of French windows, the center bar is narrower (lighter), but one or the other will find it asymmetrical.
Floor-to-ceiling elements are in vogue, giving lots of light but, in my opinion, extremely limiting possible furniture. If you don't like the view at the back of regular desks (with all the WiFi cables and extension cords included).
One more thing: large windows are more expensive than small windows. Windows are more expensive than regular walls.
We chose all double casement windows as double sash windows. There are no floor-to-ceiling elements on the top floor.
I like the 40 cm parapet height too. If it fits in with the overall concept, it is especially good in a child's room (little people playing can still look), or in the bedroom (lying down to see the beautiful garden), or in the bathroom (lying in the tub to see the beautiful garden). We decided not to do this for a variety of reasons, but we are also building more of a model home rather than an architect-designed home.
