Here is a pic of my stone mansion ground floor layout.
As you can see, I prefer room to move around as opposed to cramming. Like Burg said, I'd rather just build another stone mansion if I need more cupboard space. For my cellars, I usually just line up one wall (north side usually) with cupboards and then use the rest of the room to store tools and barrels.
Second floor is usually fairly simple as well, with a bed in the corner + some chests. Anything else (for farming, etc) can be put into stalls outside my house or be put into chests (which can be put into wagons).
Also, I'll post the layout for the storage area that I shared with DatOneGuy in world 3 if I can find it. It had a crapton of cupboards in it, and I really liked the layout.
