The fridge will pop open on moderate stops.
I'm not sure what the vertical garden is, however don't underestimate the space the front seat consumes in anything other than an upright forward position. That includes spinning the seat.
The square table position doesn't look possible with a modern console.
Your awning window crosses the side barn doors, so without reading I'm assuming you have a sliding door.
Consider access to the side storage units when the bike is in place- nothing like needing a pair of socks by the footpeg and having to move your cycle out to get them. If the forward parts are tanks and plumbing, access to the back and/or a mini pantry type slide might help. Include top access as well.
I'd question the full shower/marine toilet. You can get further with a slide out portable toilet and outside shower. For example above the porta-potty space you could fit a fridge and microwave, using the entire vertical space as the full shower would do.
I agree with mocking up the interior with boxes and masking tape, and placing the motorcycle.
Overall I think you're not trying- I mean really, just ONE bike?
Look forward to photos!
