Sokoban lessons - Three boxes (with rooms)

How many puzzles of 3 boxes are there? Probably several hundred. To carry out a selection in this jungle of puzzles, I have classified them into two big groups: "compact" puzzles, and puzzles with "rooms". I define a "room" as a structure minimum of 6 floors, connected to the rest of the puzzle for one or more passage ways (non-adjacent). For example, the following puzzle has 3 rooms (A, B, C):


This definition is operational only, and has no heuristic claim.
 
I publish below which are, in my opinion, the most beautiful puzzles of three boxes (with rooms), in chronological order. All are very simple, and with few exceptions, relatively easy.

I love this simple puzzle of unknown author! It's a recurring theme, repeatedly treated by many authors, but this one is my favorite.

This puzzle comes from the Japanese game 倉庫 ("Souko", 1999, for Windows), with 48 puzzles, all easy but very interesting.
