Bolt this shed onto your high-rise apartment, and suddenly it's like you're living down on terra firma. Not only does it give you a lush patio garden, but it solar-heats enough water for one person, collects rainwater in a tank, and shades your apartment to keep things cool on those roasty toasty summer days. Is that grass growing on the top of each one? Maybe that's the worm farm touted by the designer.
