breakfast nook
I like this concept - imagine if the kitchen extends this far in the room having a similar bench on the end of the counter, the bench on the east wall as well. this could extend to the south wall (where you have put the window in the southeast corner) or it could end earlier in the room. actually nix that. then the people on the bench would have their backs to the kitchen - better to have the bench on the south wall so people are facing the front of the house when sitting on it
or something like this - against the south wall below the window
