"Plaza", love it! In my original diagram, I ran a big column down the primary hull (next to a turbolift shaft), I think
with the intention that it was a computer core. Your image makes me realize that I've already made space for the same plaza in my schematic, hooray!
Still, my biggest challenge remains trying to figure out how Spock got to the bridge so fast in the beginning of the 2009 film
Because turbolifts move at plot speed
