Cage planning with pictures

Almost all the water is cleaned up, there is new carpet in the flooded room and hallway, and stuff is being put back so we can actually walk through the apartment. We moved the bedroom to the room with new carpet instead of putting the pigs and fish tank back in there. The new guinea pig room is wider than the other one so I want to do wider cages instead of longer ones. This room is about 10'x12' but if you want exact I have to measure it again. It needs to fit the 4' fishtank, 2' book case, Chris' desk, and all 9 guinea pigs. I think we have decided the best fit for everything now we just need to decide how to build the cages. I'm willing to do small 2nd levels but I've had it with stacked cages so all of these will sit individually in their own space. I have outlines setup but ran into trouble.

Girls' cage first:
Needs to fit 6 guinea pigs.
I put a 2x3 section from the corner to the fish tank and connected it by a 1grid wide, 2grid long section to a 3x3 area along the middle of the wall. That gives the girls(and Licorice) around 20sq ft and still allows us to reach all areas of the cage.
Ignore the stained floor. This carpet obviously needed replaced even before we moved in.

I think this is the final setup for this cage except maybe a small 2nd level. Any wider and it runs into Chris' computer chair and any longer I won't be able to clean it easily. Suggestions are still welcome.
