Studio S Squared Architecture, Inc. yes, they are. there are other photos in this book that show the view from the dining room, wtih these same cabinets on the other side. There is a pair of doors at the marble countertop that serve as a passthrough or a buffet counter.
Another design move gaining popularity is flanking an opening or pass-through with two hutches. Often this design incorporates cabinets across the top of the opening, connecting the pair of hutch cabinets.
like this hutch. needs bottom drawers but what if..... 3 window pane cupbds across the top and then put garage door in center of bottom cpbds to contain mixer. make baking center.
Not sure if this is similar to what dining area crown molding/trim would look like, but thinking it might be too much? Know ours wouldn't be as thick... ???
