Hello Witebeam;
If you made each section as an individual module, you could connect modules together as your colony grows. They might already be separate, I can’t tell. Have you made provision for escape-free feeding and cleanup?
The outworld is probably big enough for the colony you have now and maybe one more season. You’ll probably only need a nest module and the outworld to that point. If each module is separate, you could add nest modules and increase the outworld as your colony grows. The setup in the photo is probably big enough for one of my four year old colonies. It would work well if you could add modules together and eventually as your colony grows, get to the setup you picture, with a larger outworld.
I soon realized when I started making Formicaria; I can build them much faster than my ants can fill them!
