That particular kitchen was the result of the collaboration of a custom kitchen designer and the owner, who was an interior decorator. Both are very successful in the high end market.
The dimension and location of the window at that desk ties, visually, across to the other side of the kitchen to a matching door, then across the foyer, past the basement stairs/bed hall, through the music room door (same dimension) and to a matching window on the far side of the music room, 70' away. The string straightness of corners and edges, looking from one window to the other is breath-taking.
There is a grace of "placement" that uncomplicates what one sees, yet, when one "looks", there is great depth and nuance.
I don't like modern design, but this one kitchen is the best "design" I've ever been involved with in my opinion. It was a bear to accomplish, mechanically.
Speaking of
wall space, and whether a window is a wall for the purposes of kitchen counter outlets, note the window at the sink. It is a triple pane light, 16 feet long and 18 inches high, un-interrupted glass for the entire 16 feet. This wall also carries the roof load.
