Here is an idea for a vertical garden in a classroom (plus a fish tank). This could also work in other places -- homes, places of worship, community centres, etc. Maybe even outdoors? With a mesh covering over the fish tank, the cats couldn't get in.
Clever idea: Steal some space from the garage, and create a great outdoor cooking area. Create some architectural interest by covering it with barn-like doors. Gauntt Hickman( I actually just like the doors on this garage!
