We have only 2 floor-to-ceiling elements in our "old-fashioned" house, namely the patio doors. We were laughed at and sometimes put down because we didn’t want floor-to-ceiling windows everywhere but windows with a parapet.
In the meantime, many of those who first laughed at us have changed their minds because they now either stick the windows shut, put blinds in front of them, or have furniture in front of the windows.
Upstairs, we simply took 55 cm as the parapet height, with dimensions of 1.70x1.60 or 1.20x1.60, and we have wonderfully bright rooms; the boys love sitting on their windowsill and putting things on it.
And downstairs, it’s simply cozy for us that the sofa completely disappears behind the parapet, and in the kitchen and bathroom a parapet is also practical ^^
But in the new development areas here, you almost only see floor-to-ceiling windows as well, but I’m not surprised when I remember what we sometimes had to endure during the planning.
