It you moved the bunks facing port and starboard with the head of the bunks towards the center line, would that give you the room?
Think of it this way.
In a 2x2 squares stateroom, 1 of those squares needs to be walk space, so you've only got 3 out of 4 squares that can have "stuff" in them inside the room.
In a 3x2 squares stateroom, 1 of those squares still needs to be walk space, but the extra 2 can be fresher facilities.
In all my deck plan research, communal freshers start making more (deck plan) sense once you've reached 6-8 staterooms minimum, but doesn't make enough sense when dealing with 2-5 staterooms ... primarily because you're just not saving enough space by making smaller staterooms to pool together into a common fresher for everyone to use.
I know I've said this elsewhere, but it bears repeating.
If you make the simplified assumption that 4 tons=8 deck squares, then a 3x2 stateroom is 6 out of those 8 deck squares. Add in the corridor hallway outside the door and you're quickly up to those 8 squares of allocated space.
This is why I've moved in the direction of a 2.5x2 squares spacing for staterooms facing each other across a common corridor running between them.
3*4*14/1.5/1.5/3=24.88888888888889=25 = 5x5 deck squares
Which then makes
THIS possible ... with only 3 staterooms
25 deck squares
15 squares for 3 staterooms (with 2m long single beds in them)
5 squares for common galley/laundry/lounge space or medical autodoc office
5 squares for common access hallway running between them (only 20% of the total available volume is "lost" to access corridors).
4 tons * 4*14/1.5/1.5/3=33.18518518518519=33 = 5x5 plus 8 more squares ... or 6x5 plus 3 more squares ... which no matter how you slice it isn't going to look that appealing/elegantly symmetrical once you finally get down to carving up the spaces on a deck plan. Take the freshers out of each stateroom so you can have a communal fresher facility for all and your deck plan budget turns into 4x5 plus 13 more squares (of which 2-3 are going to have to be the communal fresher).
- 5x5 with individual freshers plus 8 more squares for common area including necessary walk space.
- 4x5 without freshers plus 13 more squares for common area which must also include a communal fresher and walk space.
In other words, the communal fresher is only "saving" you all of 2-4 deck squares relative to the private freshers in every stateroom option, and a significant portion of that savings is going to get eaten up by needing to allocate addition corridor walk space ... so in the end, you're really not saving a a truly useful amount of deck area/volume by going with a communal fresher. You're saving some space to add to a common room, but in a lot of configurations adding only 1-3 squares isn't going to make but so much difference in the context of the rest of the design scheme.
How you "stack" the bricks you're using is just as important as the shape of those bricks (as any Master Builder of LEGOs).
