For low maintenance areas.


A low maintenance system that requires little to no irrigation as it is a made up of recycled materials mixed into the growing medium. This type of living roof is intended to create a natural wasteland that becomes the basis for local fauna and flora to intervene into the self-germinating substrate. The system begins as a blank canvas but over time along with the building life, the top of the substrate will slowly develop with local vegetation through the influence of its surroundings. The main benefit of this build up is that it requires very little maintenance as it is self sustained and self germinating.
