Simply Build It

Toilets do not have to be against external walls. If you have bends, junctions etc in you waste pipe then you may need a manhole, we have one with a trap door above it for access. If you need a manhole it will need a double seal to stop any smells. I would suggest you ask your building inspector (if he/she is any good) but if the run is straight then I doubt you will have to do anything special.
