It’s law in Switzerland that, if the slope of a roof allows it, to make it a “living roof.” In order to meet the country’s drastic environmental goals, all buildings must replace the amount of potential meadow they take up with an equal amount on the top of their building. It does a lot of great things for the cities too; endangered orchids are flowering, the lack of hot asphalt expanses in the city means negligible urban heat-island effect, which combined with the better insulation the soil provides lowers air conditioning costs by up to 20%.

Not to mention it looks great. And reminds me of Minecraft in the best sort of way!
