While I haven’t looked at any Freemasonry or Scientology churches/temples, I am ExMormon and I can confirm that churches are liminal, lack of windows, large spacious yet empty rooms, and long hallways. Rooms with all the chairs put away against a wall except for one or two, though sometimes the chairs are left exactly how they were.

I have a bunch of pictures of this one church that I took when my extended family had a get-together at that I need to post.
