Recycled trampoline, so cool! @ Home Designer Ideas
Raised Strawberry patch, this could be waist high and rain gutter could be used for the bed. I will put gravity drip system, and a shade cover to control water loss in hot summer, could also be moved indoors or in the garage in winter. This is idea.
The column is open on the bottom so that the fish can swim up out of the pond and be at eye level if they want to.
PVC pipe structure with potted plants (squash or cucumbers) growing on it. You can walk under to pick. Nothing on the ground to get buggy or fungus, and you control your soil. Brilliant!
