In regards to the architects:
The height of a deck is not a fixed value, as far as real world military ships go. Most of the decks on my ship were about 3 meters apart, but even on the same deck you had some variation. SOme decks were as far as 5 meters apart! (Maybe more, I never measured it.)
In general, the Navy doesn't have that many people higher than 6.5 feet tall (call it 2 meters). So ceiling height needs to be at least 7 feet. However, what you aren't like aware of is all the air ducts, wiring, water pipes, and bracing that runs across the topside of just about every space, most especially P-ways (passageways). Berthings will have a little more of this than usual, due to the need to connect with the Head (bathroom). Several showers, toilets, sinks, drains, hot and cold water... Not to mention firemain, fuel lines, and God knows what else.
So about 2-3 feet of the top part of a space is going to be all this CRAP. Call it Life Support, since that's pretty much what it is. That's why most decks are bout 10 feet apart.
Some electronics spaces have a raised decking, or false-decking, and the extra cables for the gear is under that. This deck is usually a foot high or so, and there's rarely room to crawl in there comfortably, but it could be done. I don't think it goes between bulkheads though, so your PCs can't use it as a secret passage, only a secret hiding place.
Some of these spaces also seemed to have a lower ceiling than the usual; I think that may be because of armor and protective waste-spacing. But in general, you can draw your designs the way you want; there's no hard rules to it, and there are even spaces where a 6-foot person has to duck.
