I love love love these two Italian properties thought i would give you a passport for inspiration...enjoy
I love the way the tile detail creates a visual map of the space. With such high ceilings the space would feel vacant and the weight of the low couch would anchors the eye to bottom of the room. I amusing this same effect in a bathroom redo where the room is narrow but the ceiling is super high.
Notice the ceilings with the exposed beams and the heavy plaster on the walls...both of these design inspirations can be highlighted in different genres of interiors.
