A new subdivision near where I live has added The Living Wall as part of their fencing/sound barrier.

The Living Wall is a sound attenuation/privacy screening solution that incorporates ecological principals with engineering practices.

The vegetation used in The Living Wall, willow shrubs native to Canada and the US, has the ability to grow rapidly and thus provides an almost instant landscape. The construction is carefully planned to ensure the controlled growth of roots and shoots. As the vegetation spreads over it’s biodegradable wooden framework, it matures into an integrated unit that is able to withstand harsh winters and hot summers; maintaining it’s aesthetic appeal in all seasons.

Once the plants have time to grow, it will look a lot more green.
