OK, this seemed like the most reasonable place to post this, considering it had to do with architecture.
In a lot of Team Rocket fanfiction I read, it seems like everyone writes in Team Rocket Headquarters as having a pseudo-hotel-type quality. There are always rooms for members and sorts of things where they hang out and do whatever. Does anyone else just picture it as a sort of business building?
I think they've got Giovanni's office, offices for elite members, labs, and research / information libraries, and that's pretty much it. It reminds me of a science building in a college. The training facilities are different, they have quarters for recruits, but other than that, the people on Team just have to find the random cabins to stay in.
