Solar panels, LED lighting, swamp coolers: Many of the hallmarks of sustainable construction aren’t particularly aesthetically pleasing. This eight-by-4.5-foot living wall is a stunning exception. Designed by Boulder’s Perpetua Modern Garden Systems, the installation automatically feeds and waters the plants and herbs, including golden pothos, sword ferns, basil, and mint, which improve air quality. Plus, the leafy canopy brings a verdant, organic element into the contemporary LoHi home—a collaboration from Architectural Workshop, Urban Green Development, Re.Dzine, and Studio 2b—which is nicknamed the “Green Cube” not only for its LEED Platinum certification, but also because of a chartreuse Rubik’s Cube–like feature on its facade. If only going green always looked this good.
