Thinking about how ecology plays a role in urban spaces is a re-emerging trend in design. The Symbiotic Green Wall takes the idea of wall beyond its dividing role. It provides a vertical system for an entire ecosystem to exist. The wall collects, purifies and redistributes water around the site using natural processes. A digital monitoring system sheds light on water usage and overall health. It even cleans itself with purified water. I would love to see more of these sculptural installations in big cities around the world.
