Expand Minecraft automatic storage system?

The following problem: I have a large Minecraft camp and now I would like to expand it, but I think that I will break it down so that the camp does not work anymore. What do I have to do to expand a warehouse with new items?

Depends on the technique, show ma pictures. That's the only way anyone can explain you anything.

As someone has said before you have to show some pictures of the camp, otherwise you can help a lot.
