Tire climb, fun for the grandkids! I also see a raised garden. Place large platters or ply wood in the bottoms, fill with potting soil or soil substitute and have at it. Would look nice with trailing plants.
Tent filled with play sand–shade for the little, zip up to keep out cats, rain flaps to keep dry!
Small garden design perfect for an urban garden or small spaces. I never thought of putting a trellis on a balcony!
Planting for privacy - another unique idea for a living bamboo screen. White wall could be painted any colour to highlight the varigated trunks
