Looks like it’s going to be an area with an overhang for seating. Could you add storage or something useful? Yes, probably, but there are going to be high top chairs blocking it most of the time.

The only thing I could think of is that there’s more cabinets to be added, and that one is like a central pillar - that is, it’s surrounded by cabinets yet-to-be-added on all four sides.

Otherwise, yeah, I’d think it was really bizarre not to have a cabinet in there.

It’s dead space
