In our homes (where there is no terrace on the main floors) often only narrow floor-to-ceiling windows are installed. In my opinion, if these windows are half-closed by pleated blinds, they produce less light than, for example, a double-wing window.
Well, that’s not surprising. More transparent surface, more light. I find that hardly surprising. Comparing apples to oranges makes fruit salad, which is healthy and tasty, but doesn’t help here [emoji4] If it’s about the case you described: narrow floor-to-ceiling or significantly wider window with a parapet, I’m completely with you. In my home, the floor-to-ceiling elements are at least 1.01 m wide, 2.56 m high, and the rooms are large enough to have placement areas. In the bedroom and dressing room, our architects planned windows with a parapet, which makes sense for us. The choice also depends in my opinion on the local conditions, so it’s hard to generalize, I think. A bedroom facing a park-like garden without visibility from outside: I would find floor-to-ceiling, wide windows very nice because of the view, or conversely, windows with parapets are not ideal.
