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.
To include as much sunlight as possibly into this home, the designers included a large internal courtyard with skylight. Architecture firm MORIQ have designed this modern home with a huge master suite that sits facing the ocean in Amwaj, Bahrain.
