An idea for "Office Complex" came up but it requires me to delete the upper half I built already so I can proceed to make it like a multi-story building.

That has me removing the upper building's hallway and deleting the rooms on the copied lower one and changing the rooms up to give the impression of multiple floors.

But this also has me make the impression of a staircase and maybe elevator that goes "up" and "down" via switch teleport, if Boom has SR Teleport functions.
