10 foot ceilings on first floor, living room is about 18x20 if you include the hall by the stairs (purple line). We can't figure out how to make it work to make the coffers look recessed- do we drop the kitchen ceiling height and the hallway by the stairs to 9 ft and make the attached dining area a tray ceiling? But would that make the ceiling over the hallway look more like a soffit?

Or should we extend the coffered ceiling to the hallway (purple line) but then what do we do with the asymmetry at the fireplace? But that would at least make it so we could so a wall-like entrance so it looks like we ran the coffers to each "wall"?

Thanks for any thoughts or pictures!
