On the rant about this fashion of putting the room with the most potential mess factor right on top of a room you might want to keep even slightly formal...
What is it with this anyway? "Oh, I want to be with my guests while I'm preparing my special paella and drinking a crisp cold AlbariƱo while wearing a white linen tunic."
Yeah, that's an everyday thing.
For God's sake, at least make an attempt to separate what is essentially a work area. Or take your woodcrafting out of the garage and put it on the coffee table.
Now these are nice, and not completely cut off...
