[@Dark Cloud] that's absolutely fine, you can just say something like: 4 x 3 room to the north or even just: add a midsize room to the east or a Z shape room next to the guard post. Or even just ' I want a pit trap somewhere'. I know this is a weird task for a writing site and I don't expect anyone to spend a bunch of time actually drawing the dungeon. I can mock it up quickly enough and I enjoy doing so.

I also should of stated earlier: If people are not comfortable with this level of control over finicky dungeon design, I'd be happy to simplify/abstract the parts of it people don't enjoy.
