Personnel Transmat Station

The core hull has been specced to include two levels of corridors. However, it is entirely possible by the time the Spaceship BR is constructed, the core hull will have been redesigned (for structural integrity purposes) and will no longer provide a practical method for the crew to move between sections of the ship (in other words, it will be either solid LEGO or so full of beams and crossbeams and girders, I won't be able to put a corridor in it).

In the case of extreme hull redesign, each ship module will be provided with a matter transmitter station. Each transmat station will be of adequate power and quality to serve the needs of transporting crew members and personal equipment intra-ship distances.

I think this design looks too much like the shower (not yet documented), so it could change.) Either make it a free-standing raised platform, or at least replace the wall with the four scanners/emitters with an entire wall of such devices.
